                           PROSPECTUS SUMMARY

     This summary highlights selected information that we present more
fully in other sections of this prospectus.  To understand this offering,
you should read the entire prospectus carefully, including the risk factors
and financial statements.

                                ENTROPIN

     Entropin, is a development stage pharmaceutical company that has
developed Esterom(R) solution, a topical formulation for the treatment of
conditions involving impaired range of motion.  Impaired range of motion
often accompanies injuries and disorders of the shoulder and lower back, as
well as other conditions of the joints.  Esterom(R) solution is derived
from a process involving the chemical breakdown of cocaine into new and
different molecules, three of which have been patented by us.   We have
completed four preclinical animal studies and Phase I and Phase II human
clinical trials for Esterom(R) solution. These trials indicated that
Esterom(R) solution was well tolerated at the dose used. Moreover, the
range of motion with patients suffering from shoulder and back conditions
was improved significantly when compared with patients receiving a placebo.
The trials also indicated that Esterom(R) solution did not appear to have
any potential for addiction or abuse.  We began Phase III trials for
treatment of impaired range of motion due to shoulder injuries and
functionality in November 1999.  We expect to complete our Phase III trials
and submit a new drug application to the FDA in early 2001.


OUR MARKET OPPORTUNITY

     If we obtain FDA approval, we believe that there will be a substantial
market for Esterom(R) solution based on the following:

*    40 million Americans suffer from lower back conditions, according to
     a 1999 report by the American Academy of Orthopedic Surgeons.

*    Over 7 million Americans suffer from shoulder injuries or disorders,
     according to a 1996 report by the Center for Disease Control, National
     Center for Health Statistics.

*    Nearly 17.5 million Americans seek prescriptive drug therapy annually
     for the treatment of painful shoulder, acute back strain or related
     conditions, according to the National Ambulatory Medical Care Survey
     1998 report by the National Center for Health Statistics.

*    In its most recent report on lower back pain issued in 1994, the U.S.
     Agency for Health Care Policy and Research indicated that back pain
     was the second most common reason, after the common cold, for seeing
     a doctor and costs associated with back pain, including lost
     productivity, exceeded  $50 billion a year.

*    Treatments for impaired range of motion for lower back and shoulder
     conditions include steroidal drugs, non-steroidal anti-inflammatory
     drugs such as ibuprofen and muscle relaxants, all of which reduce pain
     but do not necessarily improve impaired range of motion.

                                    1
<PAGE>
OUR STRATEGY

     Our initial goal is to complete the commercialization of Esterom(R)
solution.  If we succeed, we will seek to develop products for related
muscle and joint disorders.  In order to achieve our goals, we plan to:

*    Seek FDA approval to market Esterom(R) solution for the treatment of
     impaired range of motion associated with shoulder function;

*    Seek FDA approval to market Esterom(R) solution for the treatment of
     impaired range of motion associated with lower back sprain;

*    Identify and develop other related medical applications for Esterom(R)
     solution, such as the treatment of arthritis and other joint disorders;

*    Identify and develop international markets; and

*    Minimize our fixed costs by outsourcing clinical studies, regulatory
     activities, manufacturing and sales and marketing.


     Entropin is a Colorado corporation. Our corporate offices are located
at 45926 Oasis Street, Indio, California 92201, telephone number (760)

                              redeem the warrants for at least one year
                              after the date of this prospectus.  After
                              that date, if the closing bid price of our
                              common stock on each of the 10 consecutive
                              trading days preceding our notice of
                              redemption is greater than or equal to
                              $_____ (200% of the closing bid price of our
                              common stock on the effective date of the
                              offering), we may redeem some or all of the
                              outstanding warrants upon 30 days' prior
                              written notice to the holders.  The
                              redemption price will be $0.25 per warrant.
                              If we give notice of redemption, holders of
                              the warrants will have 30 days during which
                              they may elect to exercise the warrants,
                              sell the warrants or allow the warrants to
                              be redeemed for the redemption price.

                              not consider purchase of the shares and
                              warrants  unless you can afford to lose your
                              entire investment.

                              RISK FACTORS

     The offering involves a high degree of risk.  You should carefully
consider the risks and uncertainties of this offering described below and
other information in this prospectus before investing in our common stock.
If any of these risks occur, our business, results of operation and

trading price of our common stock to decline, and you might lose part or
all of your investment.

     Many of the statements in this prospectus constitute forward-looking
statements.  These statements involve known and unknown risks,
uncertainties, and other factors that may cause our results, levels of
activity, performance or achievements to be materially different from those
implied by these forward-looking statements.  In some cases, you can
identify forward-looking statements by terminology such as "may," "will,"
"should," "expects," "plans," "anticipates," "believes," "estimates,"
"predicts," "potential," "continue" or the negative of these terms or other
comparable terminology.

     Although we believe that the expectations reflected in the forward-
looking statements are reasonable, we cannot guarantee future results,

looking statements after the date of this prospectus.


WE HAVE A LIMITED OPERATING HISTORY, A HISTORY OF LOSSES AND EXPECT FUTURE
LOSSES.

     We have no operating history upon which an investor can base an
evaluation of our company and our prospects.  Our auditor's report for year
end December 31, 1999 expressed doubt about our ability to continue as a
going concern.  We have had losses from operations since our inception in
1984 to December 31, 1999, totaling $12,518,064, and we expect to incur
future losses from operations.  At December 31, 1999 we had a total
stockholders deficit of $1,985,313.  We expect our operating expenses to
significantly increase over the next several years due to clinical testing
and other expenses related to seeking FDA approval.  Our ability to achieve
profitable operations is dependent on obtaining regulatory approval for
Esterom(R) solution, entering into agreements for product development and
commercialization, and expanding from development into successful
marketing, all of which require significant amounts of capital.  See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" beginning on page 14 and "Use of Proceeds" on page  10.



WE ARE DEPENDENT ON THE PROCEEDS OF THIS OFFERING AND MAY REQUIRE
ADDITIONAL CAPITAL.

     We have financed our business through the sale of securities and
advances from stockholders and have had no revenue from operations.  We are
dependent upon the proceeds of this offering to fund continuing operations
and management has broad discretion as to the application of the proceeds.
We may require additional capital to fund our operations.


                                    5
<PAGE>
WE WILL NOT BE ABLE TO MARKET ESTEROM(R) SOLUTION UNLESS WE OBTAIN REQUIRED
REGULATORY APPROVAL.

     The FDA approval process generally takes years and consumes
substantial capital resources with no assurance of ultimate success.  We
cannot apply for FDA approval to market Esterom(R) solution until the
product successfully completes the required Phase III clinical trials.
Several factors may prevent our  successful completion of the Phase III
clinical trials including:

     *    insufficient capital resources;
     *    inability to obtain the required number of patients to complete
          the trials; and,
     *    insufficient proof that Esterom(R) solution is safe and
          effective.


     The regulatory approval processes differ among foreign jurisdictions
and approval in one jurisdiction does not ensure other approvals.  As a
result, we may be required to undertake additional trials and incur
additional expense in order to obtain foreign approvals.  Even if we
complete the trials, we may be unable to obtain FDA approval of Esterom(R)
solution. Failure to obtain FDA or foreign jurisdictional approval would
negatively impact our business.  See "Our Business - Government Regulation"
beginning on page 19.


IF WE LOSE OUR ESTEROM(R) SOLUTION MANUFACTURER, WE WILL BE UNABLE TO BRING
ESTEROM(R) SOLUTION TO MARKET.


     We are dependent upon Mallinckrodt, Inc., our sole supplier, to
provide us with cocaine as a raw material from which the active ingredients
in Esterom(R) solution are derived.  If Mallinckrodt is unable or unwilling
to supply us, we may be unable to bring Esterom(R) solution to market.  See
"Our Business - Outsourcing" on page 18.



OUR SUCCESS DEPENDS UPON ESTEROM(R) SOLUTION'S ACCEPTANCE BY PHYSICIANS,
INSURANCE COMPANIES  AND THE PUBLIC.

     Sales of Esterom(R)'s solution depend on acceptance of the product by
physicians, insurance companies who provide pharmaceutical coverage and the
public as an alternative to, or in combination with, other therapies for
the treatment of impaired range of motion associated with painful shoulder
and other conditions.


ESTEROM(R) SOLUTION'S CLASSIFICATION AS A CONTROLLED SUBSTANCE MAY LIMIT
SALES AND INCREASE COSTS.


     As a controlled substance, Esterom(R) solution will be subject to
expensive and burdensome administrative requirements which will increase
our costs.  Moreover, these administrative requirements may discourage
Esterom(R) solution's use and acceptance by the medical community.  See
"Our Business - DEA Status" on page 21.


WE WILL BE DEPENDENT UPON THIRD PARTIES TO MARKET ESTEROM(R) SOLUTION.


     We have no experience in the sale or marketing of pharmaceutical
products and will be dependent upon third parties to sell and market
Esterom(R) solution.  If we are unable to enter into satisfactory marketing
arrangements, our sales will be adversely affected.  See "Our Business -
Outsourcing" on page 18.


                                    6
<PAGE>
IF WE ARE UNABLE TO DEFEND OUR ESTEROM(R) SOLUTION PATENTS OR IF OTHERS
DEVELOP SUBSTANTIALLY EQUIVALENT PRODUCTS, OUR BUSINESS COULD BE IMPACTED.


     Our patents, trademarks and other intellectual property rights are
important to our success.  Patent litigation can be extremely expensive and
time consuming.  If we are unable to defend our existing patents or if
others develop similar products beyond the protection of our existing
patents, our business could be impaired.   See "Our Business - Patents" on
page 19.


WE WILL BE EXPOSED TO PRODUCT LIABILITY CLAIMS.


     We will be exposed to potential product liability claims which are
inherent in the testing, manufacturing, marketing and sale of
pharmaceutical products, and product liability claims may be asserted
against us.  Product liability insurance for the pharmaceutical industry is
expensive.  There can be no assurance that adequate insurance coverage will
be available to us at acceptable costs, or that a product liability claim
would not adversely affect our business or financial condition.    See "Our
Business - Product Liability Insurance" on page 21.



A LARGE NUMBER OF OUR SHARES OF COMMON STOCK ARE ELIGIBLE FOR FUTURE SALE
WHICH COULD LOWER OUR MARKET PRICE.

      Sales of common stock after the offering, or even the potential for
those sales, are likely to lower the market price of our common stock.  In
addition, these sales may negatively affect our ability to raise needed
capital through the sale of our common stock.  The table below indicates
the number of shares outstanding, the number of shares issuable upon
exercise of options, warrants and convertible securities and which of such
shares are free trading and restricted.


     NUMBER OF
     SHARES         DESCRIPTION

     7,382,280      Common stock currently outstanding

     6,028,082      Free trading common stock outstanding

     3,621,182      Common Stock issuable upon exercise of currently
                    outstanding options and warrants

     2,000,000      Common stock issuable upon exercise of warrants
                    outstanding upon completion of offering

       230,500      Common stock issuable upon conversion of Series B
                    convertible preferred stock

     1,354,198      Common stock available for sale under Rule 144 of the
                    Securities Act



     Other than 65,000 shares, all remaining 4,179,564 shares owned by our
directors, officers, and 5% or greater stockholders, and substantially all
of the shares underlying the outstanding options and warrants are subject
to lock-up agreements which expire one year after the date of this
prospectus unless released sooner upon the written consent of the
representatives.  When the lock-up period expires, the 4,179,564 shares
subject to lock-up and the shares issuable upon exercise of options and

                                    7
<PAGE>
warrants, and conversion of preferred stock will be eligible for sale which
will have a depressive effect on the market price of our common stock.  See
"Shares Eligible for Future Sale" on page 34 and "Description of Securities
- - Other Options, Warrants and Convertible Securities" on page 33.



INVESTORS WILL EXPERIENCE DILUTION OF BOOK VALUE OF SHARES PURCHASED IN THE
OFFERING.

     Net tangible book value per share at December 31, 1999 and prior to
the offering is $(.31) per share.  Upon the sale of 2,000,000 shares of
common stock at $_____ per share, net tangible book value per share after
the offering will be $_____ per share, resulting in dilution of $_____ or
____% to investors in the offering.  Current shareholders purchased their
shares at a price below the price of the shares being offered.



OUR CONTROL WILL NOT CHANGE AFTER THE OFFERING.

     After the completion of this offering, the officers, directors and
other principal shareholders will continue to own a majority of our common
stock, and have voting control over us.


OUR STOCK HAS BEEN THINLY TRADED AND IS SUBJECT TO PRICE VOLATILITY.

     Before this offering, our stock traded on the NASD OTC Bulletin Board.
Historically:

     *    our Company has not been covered by regular reports from
          financial analysts of established standing;

     *    the limited amount and distribution of our stock has exacerbated
          the effect of relatively small imbalances in supply and demand;
          and

     *    the number of stock brokerage firms trading our common stock has
          been limited.

     Due to these factors, the trading price of our common stock could be
subject to wide fluctuations in response to quarterly variations in
operating results, changes in financial estimates by securities analysts,
announcements of technological innovations or new products by us or our
competitors or other factors.  In addition, the stock market has
experienced extreme price and volume fluctuations that have particularly
affected the market prices for many biotechnology and small capitalization
companies.


OUR STOCK AND WARRANTS MAY BECOME SUBJECT TO "PENNY STOCK" RULES.

     If our common stock were to trade for less than $5.00 per share, then
our common stock and warrants would each be considered a "penny stock"
under federal securities law. Additional regulatory requirements apply to
trading of penny stocks by broker-dealers. This could adversely effect the
trading market for our common stock and warrants.


                                    8
<PAGE>
OUR WARRANTS CAN BE REDEEMED ON SHORT NOTICE.


     At any time after one year following the date of this prospectus, we
can redeem the warrants for $0.25 per warrant on 30 days' written notice,
provided that the closing price of our common stock has been at least $___
for the ten consecutive trading days immediately preceding the notice of
redemption.  If we give notice of redemption, a holder would be forced to
sell or exercise the warrants or accept the redemption price.  See
"Description of Securities - Warrants" on page 31.



WE CAN ISSUE PREFERRED STOCK WITHOUT THE CONSENT OF OUR SHAREHOLDERS.

     Our Board of Directors may issue shares of preferred stock without
stockholder approval on such terms as the Board may determine. The rights
of the holders of common stock will be subject to, and may be adversely
affected by, the rights of the holders of any preferred stock that we may
issue in the future.  See "Description of Securities - Preferred Stock" on
page 33.


A CURRENT PROSPECTUS AND STATE BLUE SKY REGISTRATION IS REQUIRED BEFORE
PURCHASERS MAY EXERCISE THE WARRANTS.


     Purchasers of our warrants will be able to exercise the warrants only
if a current prospectus relating to the common stock underlying the
warrants is then in effect, and only if our common stock is qualified for
sale or exempt from qualification under applicable state securities laws of
the states in which the holders of the warrants reside.  Although we have
undertaken to maintain the effectiveness of a current prospectus covering
the common stock underlying the warrants, there can be no assurance that we
will be able to do so.  The value of the warrants may be impaired if a
current prospectus covering the common stock issuable upon exercise of the
warrants is not kept effective, or if the common stock is not qualified or
exempt from qualification in the states in which the holders of warrants
reside.  See "Description of Securities - Warrants" on page 31.



WE HAVE NO AGREEMENTS WITH OUR MANAGEMENT WHICH SECURE THEIR CONTINUING
SERVICE.

     Our management members are employed at will.  Therefore, a management
member may terminate employment at any time.  See "Management" beginning on
page 23.



WE ENTERED TRANSACTIONS WITH RELATED PARTIES WHICH WERE NOT SUBJECT TO
INDEPENDENT DIRECTOR APPROVAL.

     Past transactions with related parties were ratified by disinterested
directors and believed to be on terms at least as favorable as obtainable
from third parties. However, until recently, we did not have independent
directors. Future related party transactions will be subject to independent
director ratification.  See "Related Party and Other Material Transactions"
beginning on page 30.

                             USE OF PROCEEDS

     After payment of underwriting commissions and other expenses of the
offering, the net proceeds of the offering are estimated to be $________
million, or $______ million if the over allotment option is exercised.  We
expect to use the net proceeds approximately as follows:


*    Phase III clinical trials                    $              55%

*    New Drug Application for Esterom(R)          $              20%
     solution

*    Research and development of additional
     applications of Esterom(R) solution          $              10%

*    General office and administrative expenses
     and working capital (includes salaries,
     rent, travel, professional fees)             $              15%



     There may be changes in our proposed use of proceeds due to changes in
our business. Proceeds not immediately needed will be invested in treasury
bills, insured bank deposits or similar investments.  No proceeds will be
used to redeem preferred stock.



                             DIVIDEND POLICY


     We have never declared or paid dividends on our common stock and do
not intend to pay dividends on our common stock in the foreseeable future.
Instead, we will retain any earnings to finance the expansion of our
business and for general corporate purposes.  We are obligated to pay
dividends on our Series A and Series B preferred stock, although we may
elect to pay the dividends on the Series B preferred stock in shares of our
common stock.  We have paid no dividends on our Series A preferred stock.
As of December 31, 1999 we have issued 24,550 shares of common stock as
dividends on our Series B preferred stock.

                  MANAGEMENT'S DISCUSSION AND ANALYSIS
            OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW


     We were incorporated in California in 1984 as Entropin, Inc. ("old
Entropin"), and in 1998, completed an agreement and plan of merger with
Vanden Capital Group, Inc. to exchange all of the issued and outstanding
common shares of old Entropin for 5,220,000 shares of Vanden's common
stock. We were merged into Vanden, and Vanden changed its name to Entropin,
Inc.  For accounting purposes, the acquisition was treated as a
recapitalization of old Entropin based upon historical cost, with old
Entropin as the acquirer.  In conjunction with the merger, Entropin, Inc.
became a Colorado corporation.

     From our inception in August 1984, we have devoted our resources
primarily to funding our research and development efforts.  We have been
unprofitable since inception and have had no revenue from the sale of
products or other resources, and do not expect revenue for the next two
years, or until Esterom(R) solution has received FDA approval.  We expect
to continue to incur losses for the foreseeable future through the
completion of our Phase III clinical trials and the new drug application
process.  As of December 31, 1999, our accumulated deficit was
approximately $12.6 million.


PLAN OF OPERATION


     We have raised sufficient funds in 1999 to complete the first part of
a two part Phase III clinical trial program associated with the FDA
approval process for the treatment of acute painful shoulder.  The trials
began in November 1999 and the first part is scheduled for completion in
mid-2000.  We intend to use a substantial portion of the net proceeds of
our secondary offering to fund our Phase III  clinical trials through our
new drug application process related to the treatment of acute painful
shoulder and to provide funds for research and development and  working
capital.  In the future, we plan to seek FDA approval to market Esterom(R)
solution for the treatment of impaired range of motion associated with
lower back pain, and identify and develop other medical applications for
Esterom(R) solution such as applications for arthritis and other joint
disorders.  We intend to minimize our fixed costs by outsourcing clinical
studies, regulatory activities, manufacturing and sales and marketing.  We
have engaged the services of a full-time chief executive officer and
president beginning November 29, 1999 which will increase our general and
administrative expenses.


RESULTS OF OPERATIONS


     Year ended December 31, 1999 compared to year ended December 31, 1998.
Our research and development expenses were $1,743,837 for 1999, as compared
to $906,719 in 1998.  The increase in research and development resulted
primarily from initiation of Phase III clinical trials, and approximately
$200,000 from non-cash compensation expenses associated with stock options
granted to Western Center for Clinical Studies (Western).  Our general and
administrative expenses were $3,211,809 in 1999, as compared to $1,844,575
in 1998.  The increase in general and administrative expenses relates
primarily to our preparation costs for the start of Phase III clinical
trials and fund raising activities.  Moreover, the 1999 increase resulted
from an increase of approximately $1,200,000 in non-cash compensation
expense associated with stock options.

                                   14
<PAGE>
     Our interest income was $64,888 in 1999, as compared to $24,738 in
1998.  The increase was primarily a result of larger temporary cash
investment balances in 1999 from proceeds of private placements.


LIQUIDITY AND CAPITAL RESOURCES


     We have financed our operations since inception primarily through the
net proceeds generated from the sale of our common and preferred stock, and
through loans and advances from stockholders that were subsequently
converted into equity securities. From inception through December 31, 1999,
we have received net cash proceeds from financing activities aggregating
approximately $6.8 million from these transactions.  As of December 31,
1999, our working capital was $1,937,721.

     Our liquidity and capital needs relate primarily to working capital,
research and development of Esterom(R) solution, and other general
corporate requirements.  We have not received any cash from operations
since inception.  Based on our current plans, we believe the proceeds from
our secondary offering will provide sufficient capital resources to fund
our operations for at least the next 20 months.  Expectations about our
long-term liquidity may prove inaccurate if approval for Esterom(R)
solution is delayed or not obtained.  We will not generate revenue from
sales of Esterom(R) solution unless Esterom(R) solution is approved by the
FDA for marketing.

     Net cash used in operating activities was approximately $1,480,000 in
1998 and $1,617,000 in 1999.  The cash used in operations was primarily
related to funding expansion of research and development activities as well
as establishing an administrative infrastructure.  For the year ended
December 31, 1999, cash used in operating activities principally represents
the net loss for the period of $4,939,262 adjusted for non-cash stock
option compensation and an increase in accounts payable.

     As of December 31, 1999, our principal source of liquidity was
approximately $2.3 million in cash and cash equivalents.


     In April 1998, we entered into an agreement with Western to assist us
in obtaining FDA approval for Esterom(R) solution. We are required to pay
management fees of approximately $880,400 through January 5, 2001 and
$76,400 per quarter beginning January 2001 and continuing until a new drug
application is filed with the FDA. We also issued to Western stock options
to purchase 450,000 shares of our common stock at $1.50 per share.


     In August 1999, we entered into an agreement with Therapeutic
Management, Inc. to provide us clinical trial management services and
monitor all aspects of Esterom's Phase III A and B clinical studies.  In
November 1999, we entered into an agreement with Western to assume our
obligations under the Therapeutic Management Agreement.  We will pay
Western approximately $350,000 based upon completion of certain project
goals.


     In November 1999, we entered into an agreement with Western to assume
our obligations under our agreement with Therapeutic Management, Inc. to
perform tasks required to comply with FDA regulations applicable to the
conduct, coordination and management of the first Phase III trial.  Among
other things, WCCS is to select investigators, train clinical site
personnel, maintain the master file of

                                   15
<PAGE>
all pre-study and study documents, and prepare the Study Report to be
submitted to the FDA.  We will pay Western approximately $350,000 based on
completion of certain project goals.


     Our operating expenses will increase as we proceed with the two part
Phase III clinical trials through the new drug application and other
related FDA approval process.  We also expect that our general and
administrative expenses will increase significantly with the addition of
our full time chief executive officer and president.  The 20 month period
estimate for which we expect available sources of cash to be sufficient to
meet our funding needs is a forward looking statement that involves risks
and uncertainties as set forth under "Risk Factors" and elsewhere in this
prospectus.  In the event our capital requirements are greater than
estimated, we may need to raise additional capital to fund our research and
development activities.  Our future liquidity and capital funding
requirements will depend on numerous factors, including the timing of
regulatory actions for Esterom(R) solution, the cost and timing of sales,
marketing and manufacturing activities, the extent to which Esterom(R)
solution gains market acceptance, and the impact of competitors' products.
There can be no assurance that such additional capital will be available on
terms acceptable to us, if at all.  If adequate funds are not available, we
may be forced to significantly curtail our operations or to obtain funds
through entering into collaborative agreements or other arrangements that
may be on unfavorable terms.  Our failure to raise capital on favorable
terms could have a material adverse effect on our business, financial
condition or results of operations.


YEAR 2000 ISSUE


     To date we have not experienced any material difficulties or incurred
significant expenditures in connection with Year 2000 issues.  All of our
expenses have related to the opportunity cost of time spent by several of
our employees identifying and evaluating the Year 2000 compliance matters.
The agreements with Western and Therapeutic Management represent that their
software systems are Year 2000 compliant.  We contacted all other major
vendors, suppliers, financial institutions and service providers to ensure
they are Year 2000 compliant.  Key third party vendors provided a statement
in writing that their software or systems are Year 2000 compliant.

                              OUR BUSINESS

     Entropin is a development stage pharmaceutical company that has
developed Esterom(R) solution, a topical formulation for the treatment of
conditions involving impaired range of motion.  Impaired range of motion
often accompanies injuries and disorders of the shoulder and lower back, as
well as other conditions affecting body joints.  Esterom(R) solution is
derived from a process involving the chemical breakdown of cocaine into new
and different molecules, three of which have been patented by us.  We have
completed four preclinical animal studies and Phase I and Phase II human
clinical trials for Esterom(R) solution. These trials indicated that
Esterom(R) solution was well tolerated and did not appear to have any
potential for addiction or abuse.  Moreover, the range of motion with
patients in the Phase II trial suffering from shoulder and lower back
conditions was improved significantly when compared with patients receiving
a placebo.  We began Phase III trials for treatment of impaired range of
motion due to shoulder injuries and functionality  in November 1999.  We
expect to complete our Phase III trials and submit a new drug application
to the FDA in early 2001.

     Esterom(R) solution is derived through a manufacturing process
involving hydrolysis and solvolysis of cocaine in a propylene glycol and
water solution.  Hydrolysis and solvolysis are  chemical processes in which
a substance reacting with a solvent such as propylene glycol and water
solution, is changed into one or more other substances.  Through this
process, we have identified three new molecules, derivatives of
benzoylecgonine, ecgonine and ecgonidine, which form the basis of our
formulation of Esterom(R) solution and are claimed under two of our eight
United States patents.  A third United States patent claims a method for
preparing Esterom(R) solution.

REGULATORY HISTORY

     In March 1987, we filed an investigative new drug application with the
FDA which incorporated the results of our four pre-clinical animal safety
studies in which no significant toxicity was noted.  Our subsequent human
Phase I clinical safety trial for Esterom(R) solution was completed in
1991, and involved 24 healthy male subjects.  The results of this trial
indicated that Esterom(R) solution was well tolerated and showed no
significant toxicity.  Based on these results, the FDA allowed us to
initiate Phase II clinical efficacy and safety trials in 1992.

     Our Phase II clinical trial, completed in 1994, was designed to
determine the safety and  efficacy of Esterom(R) solution in patients who
had impaired range of motion due to acute lower back strain, acute painful
shoulder or the removal of a cast. The Phase II clinical trial involved 97
patients, each of whom received two topical applications of Esterom(R)
solution or placebo, with the second treatment applied 24 hours after the
first.  The results of the trial showed that Esterom(R) solution provided
statistically significant improved range of motion in both back and
shoulder conditions which was sustained for at least seven days.  There was
no clinically observed local anesthetic or analgesic effect.  The range of
motion for each condition was measured by the number of degrees to which
the subject could move the affected part in one direction or another. The
results for patients who had impaired range of motion resulting from cast
removal were inconclusive and we did not pursue this indication further.

     In 1996, we submitted our Phase III Protocol to the FDA, and a revised
Phase III Protocol in 1999.  Our Phase III studies will include two trials
in multiple clinical study centers in differing

                                   17
<PAGE>
geographic areas of the U.S.  The trials will be double-blind and placebo-
controlled in which neither patient nor doctor will know whether the
patient receives Esterom(R) solution or placebo.

     We began the first Phase III trial in November 1999 and we expect to
begin the second trial in several months.  In each of the two studies 300
patients will be enrolled for a total of 600 patients.  Of the 300 patients
in each study, 100 will receive single strength Esterom(R) solution, 100
double strength, and 100 placebo.  The second trial has a longer patient
follow-up period than the first trial.

     Our Phase III trials will test Esterom(R) solution for improved range
of motion and functionality associated solely with shoulder injuries.
Functionality involves a patient's ability to perform everyday functions,
such as hair combing  or removing a pullover sweater.  Subsequently, we
intend to seek FDA approval for treatment by Esterom(R) solution of lower
back sprain.

OUTSOURCING


     In January 1997, we entered into an agreement with Mallinckrodt, Inc.,
the only company authorized by the Drug Enforcement Agency (DEA) to provide
cocaine for medical and research purposes, and to supply and manufacture
Esterom(R) solution.  Due to federal restrictions, Esterom(R) solution
cannot be manufactured outside of the United States for sale in the United
States.  Due to DEA licensing requirements, Mallinckrodt is our sole source
for  cocaine and for producing Esterom(R) solution.  In addition, our
agreement with Mallinckrodt provides that it will comply with the Good
Manufacturing Practices  imposed by the FDA through its facilities
inspection program.  In exchange for the services, Mallinckrodt was granted
the right to be our exclusive supplier in North America and a right of
first refusal to be our exclusive world-wide supplier.


     In April 1998, we entered into an agreement with Western, to assist us
in administering the clinical trials necessary for obtaining FDA approval
of Esterom(R) solution.  Daniel L. Azarnoff, M.D., a director of Entropin,
is a director of Western.

     In August 1999, we entered into an agreement with Therapeutic
Management, Inc., a clinical research organization, to provide
comprehensive clinical trial management and monitor our first of two Phase
III clinical trials for Esterom(R) solution.

     In November 1999, we entered into an agreement with Western to perform
and assume our obligations under our agreement with Therapeutic Management
for compliance with FDA regulations.

     We do not intend to establish our own direct sales force to market
Esterom(R) solution.  Instead, we are actively pursuing strategic
relationships with pharmaceutical companies to whom we can outsource the
marketing of Esterom(R) solution.

                                   18

PATENTS

     We hold eight U. S. patents issued between 1984 and 1998 with
expiration dates ranging from September 2001 to June 2014.  These patents
include two material composition patents covering the molecules contained
in Esterom(R) solution that expire in 2012 and 2013.  Our three initial
patents were based on methods of treatment of rheumatoid arthritis using
benzoylecgonine and related compounds.  Our five subsequent patents include
compound, composition and method claims involving derivatives of the
compounds represented in the earlier patents.  Since the formula for
Esterom(R) solution contains the derivatives protected by certain of the
subsequent patents, the expiration of the earlier patents in 2001 and 2002
will not permit a replication of Esterom(R) solution by a competitor.   We
believe that some of the patents to which we have rights may be eligible
for extensions of up to five years.

     In December 1993 we filed an International Patent Application under
the Patent Cooperation Treaty claiming compounds present in the Esterom(R)
formulation from which eight separate patent applications were derived --
Australia, Canada, Europe, Hungary, Japan, New Zealand, Norway and Poland.
In addition, we have filed patent applications in China, Israel, Mexico,
South Africa and Taiwan.  From these foreign applications, nine patents
have been issued to date.

GOVERNMENT REGULATION

     The research, development, testing, manufacturing, promotion,
marketing and distribution of drug products are extensively regulated by
government authorities in the United States and other countries.  Drugs are
subject to rigorous regulation by the FDA in the United States and similar
regulatory bodies in other countries.  The steps ordinarily required before
a new drug may be marketed in the United States, which are similar to steps
required in most other countries, include:

     *    Preclinical safety studies in animals and formulation studies and
          the submission to the FDA of an Investigational New Drug (IND)
          application for a new drug;

     *    Adequate and well-controlled clinical trials to establish the
          safety and efficacy of the drug for each medical indication;

     *    The submission of a New Drug Application (NDA) to the FDA; and,

     *    FDA review and approval of the NDA.

     Preclinical animal tests include laboratory evaluation of product
chemistry, stability, pharmaceutical properties and formulation, as well as
studies to prove the product is safe in animals.  The results of
preclinical testing are submitted to the FDA as part of an NDA.   The FDA
may halt proposed or ongoing clinical trials until it  allows the trials to
continue under specified terms.

     Clinical trials to support new drug applications are typically
conducted in three sequential phases.  During Phase I safety studies, the
initial introduction of  the drug on healthy human subjects, the drug is
tested to assess how the drug is handled in the body and the level of drugs
in the body over time,  as well as side effects associated with increasing
doses.

                                   19
<PAGE>
     Phase II usually involves studies in a limited patient population to:

     - assess the efficacy of the drug in specific, targeted indications;

     - assess dosage tolerance and optimal dosage; and/or

     - identify possible adverse effects and safety risks.

     If a compound is found to be potentially effective and to have an
acceptable safety profile in Phase II evaluations, Phase III trials (also
called pivotal studies, major studies or advanced clinical trials) are
undertaken to further demonstrate clinical efficacy and to further test for
safety of the  product within an expanded patient population at
geographically dispersed clinical study sites.

     After successful completion of the required clinical testing, a NDA is
generally submitted.  The FDA may request additional information before
accepting a NDA for filing, in which case the application must be
resubmitted with the additional information.  Once the submission has been
accepted for filing, the FDA has 180 days to review the application and
respond to the applicant.  The review process is often significantly
extended by FDA requests for additional information or clarification.  The
FDA may refer the new drug application to an appropriate advisory committee
for review, evaluation and recommendation as to whether the application
should be approved, but the FDA is not bound by the recommendation of an
advisory committee.

     If FDA evaluations of the new drug application and the manufacturing
facilities are favorable, the FDA may issue either an approval letter or an
approvable letter.  An approvable letter will usually contain a number of
conditions that must be met in order to secure final approval of the new
drug application and authorization of commercial marketing of the drug for
certain indications.  The FDA may refuse to approve the new drug
application or issue a not approvable letter, outlining the deficiencies in
the submission and often requiring additional testing or information.

     The manufacturers of approved products and their manufacturing
facilities are subject to continual review and periodic inspections.
Because we intend to contract with third parties for manufacturing our
product, our control of compliance with FDA requirements will be more
complicated.  In addition, identification of certain side effects or the
occurrence of manufacturing problems after any of our drugs are on the
market could cause subsequent withdrawal of approval, reformulation of the
drug, additional clinical trials, and changes in labeling of the product.

     Outside the United States, our ability to market our products will
also be contingent upon receiving marketing authorizations from the
appropriate regulatory authorities.  The foreign regulatory approval
process includes all of the risks associated with the FDA approval set
forth above.  The requirements governing the conduct of clinical trials and
marketing authorization vary widely from country to country.  At present,
foreign marketing authorizations are applied at a national level, although
within Europe procedures are available to companies wishing to market a
product in more than one European Union, or EU, member state.

     Under a new regulatory system in the EU, marketing authorizations may
be submitted at either a centralized, a decentralized or a national level.
The centralized procedure is mandatory for the

                                   20
<PAGE>
approval of biotechnology products and high technology products and
available at the applicant's option for other products.  The centralized
procedure provides for the grant of a single marketing authorization that
is valid in all EU member states.  The decentralized procedure is available
for all medicinal products that are not subject to the centralized
procedure.  The decentralized procedure provides for mutual recognition of
national approval decisions, changes existing procedures for national
approval decisions and establishes procedures for coordinated EU actions on
products, suspensions and withdrawals.  Under this procedure, the holder of
a national marketing authorization for which mutual recognition is sought
may submit an application to one or more EU member states, certify that the
dossier is identical to that on which the first approval was based or
explain any differences and certify that identical dossiers are being
submitted to all member states for which recognition is sought.  Within 90
days of receiving the application and assessment report, each EU member
state must decide whether to recognize approval.  The procedure encourages
member states to work with applicants and other regulatory authorities to
resolve disputes concerning mutual recognition.  Lack of objection of a
given country within 90 days automatically results in approval of the EU
country.

     We will choose the appropriate route of European regulatory filing to
accomplish the most rapid regulatory approvals.  However, the regulatory
strategy may not secure regulatory approvals or approvals of the chosen
product indications.  We intend to contract with an experienced third party
to assist with our European clinical development and regulatory approvals.

DEA STATUS

     The DEA has designated Esterom(R) solution as a Schedule II controlled
substance.  The manufacture, storage, shipment and use of a Schedule II
controlled substance is subject to costly and burdensome regulations.  We
have submitted a petition to the DEA to delist Esterom(R) solution as a
Schedule II substance based on the data obtained in Phase I and II clinical
studies in human beings which indicated that Esterom(R) solution showed no
effects on the cardiovascular system and did not appear to cross the blood-
brain barrier.  The petition is currently under review by the U.S. Attorney
General's office and the FDA.  We do not expect a decision unless and until
Esterom(R) solution is approved for marketing by the FDA.

PRODUCT LIABILITY INSURANCE

     Sales of Esterom(R) solution entails risk of product liability claims.
Medical testing has historically been litigious, and we face financial
exposure to product liability claims in the event that use of Esterom(R)
solution results in personal injury.  We also face the possibility that
defects in the manufacture of Esterom(R) solution might necessitate a
product recall.  There can be no assurance that we will not experience
losses due to product liability claims or recalls in the future.  We
anticipate purchasing product liability insurance in reasonable and
customary amounts when we begin to sell Esterom(R) solution.  Such
insurance can be expensive, difficult to obtain and may not be available in
the future at a reasonable cost or in sufficient amounts to protect us
against losses due to liability.  An inability to maintain insurance at an
acceptable cost or to otherwise protect against potential product liability
could prevent or inhibit our commercialization of Esterom(R) solution.
Moreover, a product liability claim in excess of relevant insurance
coverage or product recall could have a material adverse effect on our
business, financial condition and results of operations.

                                   21
<PAGE>
ROYALTY COMMITMENTS


     In connection with our acquisition of the rights to the three original
patents for Esterom(R) solution from non-affiliated parties, we agreed to
pay a royalty of approximately 1% of amounts paid to us from the sale of
Esterom(R) solution.  We have agreed to pay a minimum royalty from actual
sales consisting of a front end payment of $40,000 and quarterly payments
of $3,572 which is  accruing from December 1, 1989, less a credit to us for
50% of patent expenses we incur.


COMPETITION

     To our knowledge, there are no products on the market which treat
impaired range of motion associated with injuries and disorders of the
shoulder and lower back.  For these conditions,  physicians often prescribe
steroidal drugs, non-steroidal anti-inflammatory drugs, pain relievers, and
muscle relaxants.  While these products reduce discomfort, they generally
do not  address impaired range of motion.

     The pharmaceutical industry is characterized by intense competition
and is subject to rapid and significant technological change.  Rapid
technological development may cause Esterom(R) solution and any other
products we develop to become obsolete before we can recoup all or any
portion of our development expenses.  Our competitors include major
pharmaceutical companies, biotechnology firms, universities and other
research institutions, both in the United States and abroad, which are
actively engaged in research and development of products in the therapeutic
areas being pursued by us.  Most of our competitors have substantially
greater financial, technical, manufacturing, marketing and human resource
capabilities than us.  In addition, many of our competitors have
significantly greater experience in testing new or improved therapeutic
products and obtaining regulatory approvals of products.  Accordingly, our
competitors may succeed in obtaining regulatory approval for their products
more rapidly than we are able to obtain approval for Esterom(R) solution.
If we commence significant commercial sales of our products, we will also
be competing with respect to manufacturing efficiencies and marketing
capabilities, areas in which we have no experience.

EMPLOYEES

     We have one full time executive officer, Thomas G. Tachovsky, our
President and Chief Executive Officer and one full time administrative
employee.  We have three part-time executive officers, Higgins D. Bailey,
Chairman of the Board and Secretary, Donald Hunter, Vice Chairman of the
Board and Treasurer and Wellington Ewen, Chief Financial Officer.  We are
actively seeking a qualified individual to serve as a full-time Chief
Financial Officer.

PROPERTIES


     We sublease 800 square feet of office space in Indio, California from
one of our principal stockholders, Thomas T. Anderson, for a monthly rent
of $800 on a month to month basis.  We believe the lease is at or below
market price for comparable office space.  Following this offering, we
intend to lease separate office space for our corporate headquarters in
Indio, California and terminate our current lease.

DIRECTOR COMPENSATION

     Our directors do not receive cash compensation for services as
directors, although they are reimbursed for out-of-pocket expenses in
attending board of directors' meetings.  Each non-salaried director
receives options to purchase 20,000 shares of our common stock for each
year of service as a director.

STOCK COMPENSATORY PLAN

     In September 1998 our board of directors authorized an employee
stock-based compensation plan, the 1998 Stock Compensatory Plan, which
provides for the grant of options intended to qualify as "incentive stock
options" or "nonqualified stock options" within the meaning of Section 422
of the United States Internal Revenue Code of 1986 (the "Code"), as well as
stock bonus shares.  Incentive stock options are issuable only to
employees.  The purposes of the plan are to attract and retain the best
available personnel, to provide additional incentives to our employees, and
to promote the success of our business.

     We have reserved 300,000 shares of common stock for issuance under the
plan, which is administered by the entire board of directors.  Under the
plan, the board of directors determines which individuals will receive
options or bonus shares, the time period during which options may be
partially or fully exercised, the number of shares of common stock that may
be purchased under each option and the option price. Options granted under
the plan are generally exercisable for a period of ten years from the date
of grant at an exercise price not less than the fair market value of the
shares at the date of grant.  Options granted under the plan generally vest
over a one to three year period from the date of the grant.  To date, we
have issued 8,031 bonus shares for services and granted no options under
the plan.

NON-QUALIFIED STOCK OPTIONS GRANTED TO EXECUTIVE OFFICERS DURING 1999

     The following table sets forth certain information regarding grants of
stock options to our Executive Officers who received stock options during
1999.  The fair value of the option grant was estimated on the date of the
grant utilizing the Black-Scholes option pricing model with the following
assumptions: 51% to 100% volatility, five year life, risk free rate of
return of 5.5% to 6.2% and a 0% dividend yield.  None of the following
options have been exercised.

              RELATED PARTY AND OTHER MATERIAL TRANSACTIONS

     During 1996 and 1997, we were advanced an aggregate of $83,873 by
Higgins D. Bailey, our former President, current Chairman and a principal
stockholder.  These advances were paid in full January 1998.

     We sublease approximately 800 square feet of office space from Thomas
T. Anderson, one of our principal stockholders.  The rent on the sublease
is $800 per month.  We believe this is a competitive lease rate for similar
real estate in the area where the office is located.

     On January 15, 1998, we  converted $1,710,487 of long-term debt and
accrued interest incurred for cash advances and past services associated
with research and development into 1,710,487 shares of our redeemable 8%
non-voting, non-cumulative Series A Preferred Stock at $1.00 per share.
The debt was owed to Higgins D. Bailey, Thomas T. Anderson and Lowell Somers.


     We owed Dr. James E. Wynn $1,500,000 for research and development
services provided from 1984 through 1997 as evidenced by an 8% Note due
December 31, 2000.  In January 1998 we converted this obligation to
1,500,000 shares of our non-voting, non-cumulative redeemable 8% Series A
preferred stock, valued at $1.00 per share.  In addition, in December 1997,
certain of our stockholders contributed shares of our common stock to Dr.
Wynn for research and development services (259,042 shares valued at
$712,000, or $2.75 per share).  The expense and related capital
contributions were reflected at December 31, 1997.  Dr. Wynn was
subsequently appointed one of our directors in February 1998.

     In January 1998, we granted Dr. Wynn a non-exclusive right for three
years to develop both improved products and new products from our
proprietary and confidential information.  Improved products are those that
contain the same active ingredients as Esterom(R) solution, but that are
formulated differently.  New products are those which are developed from
cocaine or a derivative and are separately patentable.  We will have all
rights to the improved and new products.  Dr. Wynn will receive a two
percent royalty on the net commercial sales of any improved products he
develops.  The royalty percentage on any new products he develops is to be
determined through negotiation.  If agreement is not reached, the royalty
is to be determined by an arbitrator with pharmaceutical industry experience.

     In April 1998 we entered into an agreement, as amended July 21, 1999,
with Western to assist us in completing the Phase III study and new drug
application phase for FDA approval of Esterom(R) solution for limited range
of motion associated with shoulder injuries and disorders.  We are paying
$880,400 over the period from April 1998 through January 5, 2001, and
$76,400 per quarter commencing January 2001 and continuing until NDA
submission.  We also granted Western options to purchase an aggregate of
450,000 shares of our common stock at $1.50 per share for a term of five
years.  The options vest at various times based upon performance.   Daniel
L. Azarnoff, M.D.,  a director of  Entropin is also a director of Western.


                                   30

<PAGE>
     In November 1999, we entered into an agreement with Western to assume
our obligations under our agreement with Therapeutic Management, Inc. to
perform tasks required to comply with FDA regulations applicable to the
conduct, coordination and management of the first Phase III trial.  Among
other things, WCCS is to select investigators, train clinical site
personnel, maintain the master file of all pre-study and study documents,
and prepare the Study Report to be submitted to the FDA.  We will pay
Western approximately $350,000 based on completion of certain project goals.


     These transactions are believed to be as favorable as obtainable from
third parties and were approved by directors who did not have an interest
in the transactions. However, at the time of the transactions we did not
have any independent disinterested directors to ratify the transactions.
All future material related party transactions and loans will be made or
entered into on terms that are no less favorable than those that can be
obtained from non-related third parties. In addition, all future material
related party transactions and loans, and any forgiveness of loans, must be
approved by a majority of our independent directors who do not have an
interest in the transactions and who have access, at our expense, to our
legal counsel or to independent legal counsel.


                        DESCRIPTION OF SECURITIES

     Our authorized capital stock consists of 50,000,000 shares of common
stock, $.001 par value per share, and 10,000,000 shares of preferred stock,
$.001 par value per share.

COMMON STOCK


     At February 28, 2000 there were 7,382,280 shares of common stock

stockholders, and cumulative voting is not permitted.  Upon issuance,
shares of common stock are not subject to further assessment or call.
Subject to the prior rights of any series of preferred stock that may be
issued by us, holders of common stock are entitled to receive ratably such
dividends that may be declared by the board of directors out of funds
legally available therefor and are entitled to share ratably in all assets
remaining after payment of liabilities in the event of our liquidation,
dissolution or winding up.  Holders of common stock have no preemptive
rights or rights to convert their common stock into any other securities.
All outstanding shares of common stock are, and all shares of common stock
to be outstanding upon completion of this offering will be, fully paid and
nonassessable.


WARRANTS

     Each warrant will entitle the holder to purchase one share of common
stock at an exercise price of $______ per share (150% of the initial public
offering price of the shares).  The warrants will generally be exercisable
at any time for five years after the date of this prospectus, unless
earlier redeemed.  The warrants are redeemable by us, at a price of $0.25
per warrant:

     *    upon 30 days' prior written notice;

                                   31
<PAGE>
     *    no earlier than one year from the date of this prospectus; and then

     *    only if the closing bid price of the common stock equals or
          exceeds $______ (200% of the initial public offering price of the
          shares), per share for the 10 consecutive trading days
          immediately preceding the date of notice of redemption.

     If we give notice of our intention to redeem, a holder must either:

     *    sell or exercise the warrants before the date specified in the
          redemption notice; or

     *    accept the redemption price.

     The warrants will be issued in registered form under a warrant
agreement between us and Corporate Stock Transfer, Inc., as warrant agent.
The shares of common stock underlying the warrants, when issued upon
exercise of a warrant, will be fully paid and nonassessable.  We will pay
any transfer tax incurred as a result of the issuance of common stock to
the holder upon its exercise.

     The warrants contain provisions that protect the holders against
dilution by adjustment of the exercise price.  These adjustments will occur
if there is a merger, stock split or reverse stock split, stock dividend or
recapitalization and they could occur in other situations.  We are not
required to issue fractional shares upon the exercise of a warrant.  The
holder of a warrant will not possess any rights as our shareholder until he
or she exercises the warrant.

     A warrant may be exercised by surrendering the warrant certificate

     *    on or before the expiration or redemption date of the warrant at
          the offices of the warrant agent; with

     *    the form of "Election to Purchase" on the reverse side of the
          warrant certificate completed and executed as indicated; and

     *    payment of the exercise price by certified or bank check payable
          to the order of Entropin, Inc. for the number of shares for to
          which the warrant is being exercised.

In order for a holder to exercise the warrants, there must be

     *    a current registration statement in effect with the Securities
          and Exchange Commission; and,

     *    qualification in effect under applicable state securities laws or
          applicable exemptions from state qualification requirements, with
          respect to the issuance of common stock or other securities
          underlying the warrants.

                                   32
<PAGE>
      We have agreed to use all commercially reasonable efforts to cause a
registration statement with respect to such securities under the Securities
Act to be filed and to become and remain effective in anticipation of and
before the exercise of the warrants and to take such other actions under
the laws of various states as may be required to cause the sale of common
stock or other securities upon exercise of warrants to be lawful.  We will
not be required to honor the exercise of warrants if, in the opinion of our
board of directors with the advice of counsel, the sale of securities upon
exercise would be unlawful.

     For the life of the warrants, the holders have the opportunity to
profit from a rise in the market price of the common stock without assuming
the risk of ownership of the shares of common stock underlying the
warrants.  The warrant holders may be expected to exercise their warrants
at a time when we would, in all likelihood, be able to obtain any needed
capital by an offering of common stock on terms more favorable than those
provided for by the warrants.  Furthermore, the terms on which we could
obtain additional capital during the life of the warrants may be adversely
affected.

OTHER OPTIONS, WARRANTS AND CONVERTIBLE SECURITIES

     We have outstanding options and warrants to purchase an aggregate of
3,621,182 shares of our common stock, at exercise prices ranging from $1.50
to $5.00 per share and expiration dates ranging from July 2004 to February
2008.  Additionally, there are 230,500 shares issuable upon conversion of
the Series B preferred stock.

PREFERRED STOCK

     Our Board of Directors has the authority, without further action by
the stockholders, to issue up to 10,000,000 shares of preferred stock in
one or more series and to fix the powers, designations, preferences and
relative, participation, option or other rights thereof, including dividend
rights, conversion rights, voting rights, redemption terms, liquidation
preferences, sinking fund terms and the number of shares constituting any
series.  The issuance of preferred stock in certain circumstances may have
the effect of delaying, deferring or preventing a change in control of our
company, may discourage bids for our common stock at a premium over the
market price of the common stock, and may adversely affect the market price
of, and the voting and other rights of the holders of the common stock.

     Our Board of Directors has designated 3,210,487 shares of preferred
stock as Series A redeemable non-voting preferred stock, of which all were
issued to four holders of record in exchange for our promissory notes and
deferred compensation.  Series A preferred stock is designated as
redeemable eight (8%) percent non-cumulative non-voting preferred stock and
redeemable only from 20% of annual "Earnings", but not to exceed "Net Cash
Flow from Operating Activities" as those terms are defined under GAAP.  The
Series A preferred stock will be automatically canceled on January 16,
2005, if not fully redeemed within that time period.

     Our Board of Directors has designated 400,000 shares of preferred
stock as convertible Series B redeemable non-voting preferred stock, of
which 245,500 shares were issued and 230,500 shares remain outstanding held
by 33 holders of record.  Series B preferred stock is designated as redeemable

                                   33
<PAGE>
ten (10%) percent cumulative non-voting preferred stock with $.001 par
value and convertible on a one for one basis into common stock.  At our
election, annual dividends may be paid in cash and/or in shares of our
common stock, at the rate of one share of common stock for each $5.00 in
accrued dividends.   We may redeem at any time, in whole or in part based
on a pro rata basis with other holders of the Series B preferred stock, the
outstanding Series B preferred stock  upon 30 days' notice at $5.00 per
share plus accrued and unpaid dividends from the date of issuance up to the
expiration date.  All issued and outstanding Series B preferred stock must
be redeemed in full on or before July 15, 2003.


     We will not offer preferred stock to officers, directors or holders of
5% or more of our securities except on the same terms as offered to all
other existing shareholders or new shareholders, or unless the issuance of
preferred stock is approved by a majority of our independent directors who
do not have an interest in the transaction and who have access, at our
expense, to our legal counsel or to independent legal counsel.


STOCK TRANSFER AGENT

     Corporate Stock Transfer, Inc., Denver, Colorado is our transfer
agent.  The transfer agent's address is 3200 Cherry Creek Drive South,

LIMITATIONS ON DIRECTORS' AND OFFICERS' LIABILITY

     Our Amended Articles of Incorporation limit the liability of directors
to stockholders for monetary damages for breach of a fiduciary duty except
in the case of liability: (i) for any breach of their duty of loyalty to us
or our stockholders; (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law; (iii) for
unlawful distributions as provided in Section 7-108-403 of the Colorado
Business Corporation Act; or (iv) for any transaction from which the
director derived an improper personal benefit.

     Our Articles of Incorporation and Bylaws provide for the
indemnification of our directors and officers to the maximum extent
permitted by law, including Section 7-109-102 of the Colorado Business
Corporation Act, against all liability and expense (including attorneys'
fees) incurred by reason of the fact that the officer or director served in
such capacity, or in a certain capacity for another entity at our request.
Section 7-109-102 of the Colorado Business Corporation Act provides
generally for indemnification of directors against liability incurred as a
result of actions, suits or proceedings if they acted in good faith and in
a manner they reasonably believed to be in or not opposed to our best interests.

                     SHARES ELIGIBLE FOR FUTURE SALE


     We presently have outstanding 7,382,280 shares of common stock of
which 6,028,082 shares are free trading.  However, we entered into lock-up
agreements with our officers and directors and 5% stockholders which,
except for 65,000 shares, requires that all remaining 4,184,621 shares of
common stock owned by such persons may not be sold for a period of one year
following the date of this prospectus without the prior written consent of
the representatives.


                                   34
<PAGE>

     We have agreed to register 711,200 shares of common stock under the
Securities Act of 1933, on behalf of certain stockholders.  We may be
required to file a registration statement as soon as practicable from the
date of the closing of this offering, at our expense, under the Securities
Act, with respect to these shares of common stock, and to use our best
efforts to effect the registration, subject to some conditions and
limitations.  At such time as these shares may be registered, they will be
free trading.  If we propose to register any of our securities under the
Securities Act, either for our own account or for the account of other
security holders, the holders of registration rights will be entitled to
notice of the registration and will be entitled to include, at our expense,
their shares in the registration


     We have issued 1,354,198 shares of common stock which are "restricted"
shares subject to restrictions upon resale under Rule 144 under the
Securities Act.  In general, under Rule 144, as currently in effect, any
person (or persons whose shares are aggregated), including  persons deemed
to be affiliates, whose restricted securities have been fully paid for and
held for at least one year from the later of the date of payment therefor
to us or acquisition thereof from an affiliate, may sell such securities in
brokers' transactions or directly to market makers, provided that the
number of shares sold in any three month period may not exceed the greater
of 1% of the then outstanding common stock or the average weekly trading
volume of the common stock during the four calendar weeks preceding such
sale.  Sales under Rule 144 are also subject to certain notice requirements
and the availability of current public information about us.  After two
years have elapsed from the later of the issuance of restricted securities
by us or their acquisition from an affiliate, such securities may be sold
without limitation by persons who are not affiliates under Rule 144.  The
1,354,198 shares of restricted stock become eligible for sale at various
times during the period April through September 2000, with 35,500 shares
subject to the lock-up agreement described above.


     Sales of substantial amounts of common stock by our stockholders under
Rule 144 or otherwise, or even the potential for such sales, are likely to
have a depressive effect on the market price of the shares of common stock
and warrants and could impair our ability to raise capital through the sale
of our equity securities.

                              UNDERWRITING


     The underwriters named below for whom Neidiger, Tucker, Bruner, Inc.
and Westport Resources Investment Services, Inc. are acting as
representatives, have severally agreed, under the terms and conditions of
an underwriting agreement with us and the underwriters, to purchase from
us, and we have agreed to sell to them, the number of shares and warrants
set forth in the table below at the prices set forth on the cover page of
this prospectus.

    Underwriters                      Number of Shares    Number of Warrants

<PAGE>
     If any shares and warrants are purchased, the underwriters are
committed to purchase all of the 2,000,000 shares and warrants offered by
this prospectus, but not the 300,000 shares and the 300,000 warrants
subject to the over-allotment option.  The underwriting agreement also
provides that if an underwriter defaults, the purchase commitments of  the
non-defaulting underwriters may be increased or this offering may be
terminated.


     Once the underwriters have purchased the shares and warrants at the
public offering prices of $______ per share and $______ per warrant less
the 8% underwriting discount, they will offer the  shares and warrants in
units consisting of one share and one warrant to the public at the public
offering prices and to other broker-dealers who are members of the selling
group at that price minus a concession of $______ per share and $______ per
warrant.  The underwriters and selling group members may allow a discount
of $______ per share and $______ per warrant on sales to other broker-
dealers, including the underwriters.  After the public offering of the
shares and warrants, the public offering price, the concessions to selling
group members and the discount to other broker-dealers may be changed by
the representatives.


     We have granted the underwriters an option, expiring at the close of
business 45 days after the date of this prospectus, to purchase up to
300,000 additional shares and 300,000 additional warrants from us on the
same terms as apply to the sale of the shares and warrants set forth above.
The underwriters may exercise the option only to cover over-allotments
incurred in the sale of the shares and warrants.


     The representatives have informed us that they do not expect the
underwriters to confirm sales of shares and warrants on a discretionary basis.


     The following table summarizes the discounts and estimated expenses
that we will pay to the underwriters:

     We have also agreed to issue to the representatives warrants that
entitle the holder to purchase up to 200,000 shares at an exercise price of
$______ per share and to purchase up to 200,000 warrants to purchase
200,000 shares at $______ per share.  The representatives' warrants may not
be exercised for at least one year and will be restricted from sale,
transfer, assignment, or hypothecation for a period of five years from the
effective date of the offering, except to officers or partners (not
directors) of the representatives and members of the selling group and/or
their officers or partners.  The representatives' warrants are not
redeemable by us.  We have agreed to maintain an effective registration
statement

                                   36
<PAGE>
with respect to the issuance of the securities underlying the
representatives' warrants, if necessary, to allow their public resale
without restriction, at all times during the period in which the
representatives' warrants are exercisable, beginning one year after the
date of this prospectus.  Such securities are being registered on the
registration statement of which this prospectus is a part.


     The underwriting agreement provides for indemnification between us and
the underwriters against some liabilities, including liabilities under the
Securities Act of 1933 and for contribution by us and the underwriters to
payments that may be required to be made in respect of those liabilities.
Insofar as indemnification for liabilities under the Securities Act may be
permitted to our directors, officers and controlling persons under the
agreement between us and the underwriters, or otherwise, we have been
advised that in the opinion of the SEC this indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable.


     We have agreed that, for a period of one year following the completion
of this offering, we generally will not offer, sell, contract to sell,
grant any option for the sale or otherwise dispose of any of our common
stock without the consent of the representatives.  Our officers, directors
and the holders of 5% or more of our outstanding common stock (aggregating
4,184,621 shares) have agreed that for a period of one year following the
date of this prospectus, they will not offer, sell, contract to sell, grant
any option for the sale or otherwise dispose of any of our common stock,
other than intra-family transfers or transfers to trusts for estate
planning purposes, without the consent of the representatives, which will
not be unreasonably withheld.


     We have applied for listing of our common stock and warrants on the
Nasdaq SmallCap Market.  If listing is approved, our common stock will
trade under the symbol "ETOP" and our warrants will trade under the symbol
"ETOPW".

     Prior to this offering, our common stock has traded on the NASD OTC
Bulletin Board and there has been no public market for our warrants.  Stock
that trades on the OTC Bulletin Board can experience a relatively inactive
trading market, or low trading volume, high volatility and/or trading
prices that may not bear any reasonable relationship to the financial
condition or book value of the company.

     We can offer no assurances that the public offering price will
correspond to the price at which the common stock and warrants will trade
in the public market subsequent to the offering or that an active trading
market for the common stock and warrants will develop and continue after
the offering.


     The representatives on behalf of the underwriters may engage in over-
allotment, stabilizing transactions, syndicate covering transactions and
penalty bids in accordance with Regulation M under the Securities Exchange
Act of 1934.


     *    Over-allotment involves syndicate sales in excess of the offering
          size, which creates a syndicate short position.

     *    Stabilizing transactions permit bids to purchase the underlying
          security so long as the stabilizing bids do not exceed a
          specified maximum.

                                   37
<PAGE>
     *    Syndicate covering transactions involve purchases of the common
          stock and warrants in the open market after the distribution has
          been completed in order to cover syndicate short positions.


     *    Penalty bids permit the representatives to reclaim a selling
          concession from a syndicate member when the shares and warrants
          originally sold by the syndicate member are purchased in a
          syndicate covering transaction to cover syndicate short
          positions.


     These stabilizing transactions, syndicate covering transactions and
penalty bids may cause the price of the common stock and warrants to be
higher than it would otherwise be in the absence of such transactions.
These transactions may be effected on the Nasdaq SmallCap Market or
otherwise and, if commenced, may be discontinued at any time.

                              LEGAL MATTERS


     Certain legal matters with respect to the validity of the common stock
and the warrants to purchase common stock offered hereby will be passed
upon for us by Brenman Bromberg & Tenenbaum, P.C., Denver, Colorado.
Members of the firm of Brenman Bromberg & Tenenbaum, P.C. own 59,855 shares
of our common stock.  A. Thomas Tenenbaum, a director of Brenman Bromberg
& Tenenbaum, P.C., was our CEO prior to our merger with old Entropin.  The
Law Office of Gary A. Agron, Englewood, Colorado has acted as counsel to
the representatives in connection with this offering.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS



   The Board of Directors and Stockholders
   Entropin, Inc.


   We  have  audited  the  accompanying  balance  sheet  of  Entropin,  Inc.  (a
   development  stage company) as of December 31, 1998 and 1999, and the related
   statements of operations,  changes in stockholders' equity (deficit) and cash
   flows for the years  then  ended and for the  period  from  August  27,  1984
   (inception)  through  December 31, 1999.  These financial  statements are the
   responsibility of the Company's management.  Our responsibility is to express
   an opinion on these financial statements based on our audits.

   We  conducted  our audits in  accordance  with  generally  accepted  auditing
   standards.  Those  standards  require  that we plan and perform the audits to
   obtain reasonable  assurance about whether the financial  statements are free
   of  material  misstatement.  An audit  includes  examining,  on a test basis,
   evidence supporting the amounts and disclosures in the financial  statements.
   An  audit  also  includes  assessing  the  accounting   principles  used  and
   significant  estimates made by management,  as well as evaluating the overall
   financial  statement  presentation.  We  believe  that our  audits  provide a
   reasonable basis for our opinion.

   In our opinion, the financial statements referred to above present fairly, in
   all  material  respects,  the  financial  position  of  Entropin,  Inc. as of
   December  31,  1998 and 1999 and the results of its  operations  and its cash
   flows for the years  then  ended and for the  period  from  August  27,  1984
   (inception)  through December 31, 1999, in conformity with generally accepted
   accounting principles.

   The accompanying  financial  statements have been prepared  assuming that the
   Company  will  continue as a going  concern.  As  discussed  in Note 1 to the
   financial  statements,  the Company is in the development  stage and has been
   primarily  involved in research  and  development  activities,  resulting  in
   significant  losses  and an  accumulated  deficit  at  December  31,  1999 of
   $12,640,814  These  conditions raise  substantial  doubt about its ability to
   continue as a going concern.  Management's plans regarding those matters also

                           NOTES TO FINANCIAL STATEMENTS
                             December 31, 1998 and 1999




1. Organization and summary of significant accounting policies

   Organization:

   Entropin, Inc., a Colorado corporation, was organized in August 1984, to be a
   pharmaceutical  research company developing  Esterom(R) solution, a topically
   applied  compound for the  treatment of impaired  range of motion  associated
   with acute  lower back  sprain and acute  painful  shoulder.  The  Company is
   considered  to be a  development  stage  enterprise  as more fully defined in
   Statement No. 7 of the Financial Accounting Standards Board.  Activities from
   inception  include research and  development,  seeking the U.S. Food and Drug
   Administration  (FDA)  approval  for  Esterom(R)  solution,  as  well as fund
   raising.

   On January 15, 1998, the Company  consummated an agreement and plan of merger
   with Vanden Capital Group, Inc., a Colorado  corporation,  (Vanden), in which
   Vanden  acquired  all of the  issued  and  outstanding  common  shares of the
   Company (see Note 5). The Company was merged into Vanden,  and Vanden changed
   its name to Entropin,  Inc. For accounting purposes, the acquisition has been
   treated as a recapitalization of the Company, based upon historical cost, and
   a reverse acquisition with the Company as the acquirer.

   Basis of presentation and management's plans:

   The Company's  financial  statements  have been  presented on a going concern
   basis which  contemplates  the realization of assets and the  satisfaction of
   liabilities  in  the  normal  course  of  business.  The  Company  is in  the
   development stage and has been primarily involved in research and development
   activities.  This has  resulted  in  significant  losses  and an  accumulated
   deficit  at  December  31,  1999  of  $12,640,814.  The  Company's  continued
   existence  is  dependent  on its  ability  to obtain the  additional  funding
   necessary to complete the FDA approval  process for  Esterom(R)  solution and
   market the product.

   As described in Note 5, the Company successfully  completed  recapitalization
   of the Company in January  1998.  The Company also sold private  offerings of
   245,500 shares of Series B convertible  preferred stock for gross proceeds of
   $1,227,500  (Note 4),  $200,000 of convertible  notes payable,  and 1,508,700
   shares of common  stock for gross  proceeds  of  $4,664,800  (Note 5),  which
   offerings  provide  liquidity  to the  Company for  current  operations.  The
   Company raised  sufficient  funds in 1999 to complete the first part of a two
   part  Phase III  clinical  trial  program  associated  with the FDA  approval
   process for the  treatment  of acute  painful  shoulder.  The trials began in
   November  1999 and the first part is scheduled  for  completion  in mid 2000.
   Management  is  confident  that it will raise the added  funds  necessary  to
   complete the second part of the Phase III trials,  ancillary  studies and the
   New Drug Application (NDA) process,  as well as additional funds for research
   and development and working  capital via a secondary  securities  offering in
   early 2000. The Company estimates it will require additional funding of up to
   $10 million to successfully  complete the FDA approval process. The financial
   statements do not include any adjustment  relating to the  recoverability and
   classification of recorded asset amounts or the amount and  classification of
   liabilities or other  adjustments  that might be necessary should the Company
   be unable to continue as a going concern in its present form.

                           NOTES TO FINANCIAL STATEMENTS
                             December 31, 1998 and 1999




1. Organization and summary of significant accounting policies (continued)

   Use of estimates:

   The preparation of financial statements in conformity with generally accepted
   accounting  principles  requires management to make estimates and assumptions
   that affect the reported  amounts of assets and liabilities and disclosure of
   contingent assets and liabilities at the date of the financial statements and
   the reported  amounts of revenues and expenses  during the reporting  period.
   Actual results could differ from those estimates.

   Income Taxes:

   The Company provides for income taxes utilizing the liability  approach under
   which  deferred  income  taxes are  provided  based upon enacted tax laws and
   rates applicable to the periods in which the taxes become payable.

   Property and equipment:

   Office furniture and equipment is recorded at cost. Depreciation commences as
   items are placed in service and is computed  on a  straight-line  method over
   their estimated useful lives of three years.

   Leasehold  improvements are recorded at cost and amortized over the five-year
   term of the lease.

   Patents:

   Patents are stated at cost less accumulated  amortization which is calculated
   on a  straight-line  basis over the useful lives of the assets,  estimated by
   management to average 16 years.  Research and development costs and any costs
   associated  with  internally  developed  patents (with the exception of legal
   costs) are expensed in the year incurred.

   The  Company  holds  eight U.S.  patents  issued  between  1984 and 1998 with
   expiration  dates  ranging from  September  2001 to June 2014.  These patents
   include two material  composition patents covering the molecules contained in
   Esterom(R) solution that expire in 2012 and 2013. The Company's three initial
   patents  were based on methods of  treatment of  rheumatoid  arthritis  using
   benzoylecgonine  and  related  compounds,  and the  five  subsequent  patents
   include compound,  composition and method claims involving  derivative of the
   compounds  represented in the earlier patents. The Company believes that some
   of the patents may be eligible for extensions of up to five years.

   In December 1993, the Company filed an International Patent Application under
   the Patent  Cooperation  Treaty claiming  compounds present in the Esterom(R)
   solution  formulation  from which eight  separate  patent  applications  were
   derived - Australia,  Canada, Europe, Hungary, Japan, New Zealand, Norway and
   Poland. In addition,  the Company filed patent applications in China, Israel,
   Mexico,  South  Africa and  Taiwan.  From these  foreign  applications,  nine
   patents have been issued to date.

1. Organization and summary of significant accounting policies (continued)

   Impairment of long-lived assets:

   The Company  evaluates  the  potential  impairment  of  long-lived  assets in
   accordance  with  Statement  of  Financial   Accounting  Standards  No.  121,
   "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets
   to be  Disposed  of".  The  Company  annually  reviews the amount of recorded
   long-lived assets for impairment.  If the sum of the expected cash flows from
   these assets is less than the carrying amount,  the Company will recognize an
   impairment loss in such period.

   Cash equivalents:

   For the purposes of the  statement of cash flows,  the Company  considers all
   highly liquid debt  instruments  purchased with a maturity of three months or
   less to be cash equivalents.

   Deferred stock offering costs:

   Deferred stock offering costs  represent costs incurred to December 31, 1999,
   in connection with the proposed offering of common stock (see Note 5). In the
   event that such  offering is  successful,  costs  incurred as of December 31,
   1999, and additional  costs incurred  subsequent to that date will be charged
   against the proceeds of the offering; if the offering is not successful,  the
   costs will be charged to operations.

   Concentrations of credit risk:

   Financial instruments which potentially subject the Company to concentrations
   of credit risk consist principally of cash and cash equivalents.  The Company
   places its cash with high quality financial institutions. At times during the
   periods, the balances at financial institutions exceeded FDIC limits.

   Stock-based compensation:

   The Company  has  adopted  Statement of Financial  Accounting  Standards  No.
   123, Accounting for  Stock-Based  Compensation.  Compensation costs for stock
   options is  measured as  the excess, if any, of the fair value of the options
   at date of grant over the exercise price.

2. Related party transactions

   Lease agreement:

   The Company  subleases  approximately  800 square feet of office space from a
   principal stockholder, at $800 per month.

2. Related party transactions (continued)

   Conversion of long-term debt - stockholders:

   On January 15, 1998, the Company  converted  $1,710,487 of long-term debt and
   accrued  interest,  incurred for cash advances and past  services  associated
   with  research  and  development,  into  1,710,487  shares of 8%  non-voting,
   non-cumulative  Series A preferred stock at $1.00 per share (see Note 4). The
   debt was owed to significant stockholders.

3. Income taxes

   The  consummation  of the stock  exchange  with  Vanden and the  issuance  of
   preferred  stock in January  1998 (see Note 5),  resulted  in a change in the
   Company's  tax status from an S  corporation  to a taxable  corporation.  The
   effect of the change is to provide for income tax based upon reported results
   of  operations,  and to  provide  deferred  tax  assets  and  liabilities  on
   temporary differences between reported earnings and taxable income.

   At December 31, 1999,  the Company has net operating  loss  carryforwards  of
   approximately $3,558,000 and future tax deductions of $6,946,000 which may be
   used to offset  future  taxable  income.  The  future tax  deductions  result
   primarily from utilizing the cash basis for income tax reporting purposes and
   unearned   stock   compensation.   The   difference   between  the  tax  loss
   carryforwards  and future  tax  deductions  and the  cumulative  losses  from
   inception  result from the losses  previously  incurred by the S corporation.
   The net operating loss carryforwards  expire in 2018 and 2019.  Approximately
   $250,000 of the net operating loss  carryforward  is limited as to the amount
   which may be used in any one  year.  At  December  31,  1998 and 1999,  total
   deferred tax assets and the valuation allowance are as follows:

                                                    1998         1999

   A 100%  valuation  allowance  has been  established  against the deferred tax
   assets,  as utilization of the loss  carryforwards  and  realization of other
   deferred tax assets cannot be reasonably assured.

4. Redeemable preferred stock

   In  December  1997,  the Board of  Directors  approved  an  amendment  to the
   Articles of Incorporation to authorize  10,000,000  shares of $.001 par value
   preferred  stock. On January 15, 1998, the Company issued 3,210,487 shares of
   its Series A redeemable,  non-voting,  non-cumulative  8% preferred  stock in
   exchange  for an  aggregate  $1,710,487  of notes  payable  to  shareholders,
   accrued  interest,  and a $1,500,000  compensation  agreement.  The annual 8%
   dividend is based upon a $1.00 per share  value,  and is only  payable out of
   earnings.

   The Series A preferred stock is subject to mandatory  redemption.  The shares
   are redeemable only from 20% of annual  earnings,  but not exceeding net cash
   flow from, operating activities, and will automatically cancel on January 16,
   2005, if not fully redeemed.  The Company may voluntarily  redeem outstanding
   shares of preferred stock at $1 per share.

   In July 1998, the Company  completed a private placement of 245,500 shares of
   Series B  preferred  stock at $5.00 per  share,  for total  net  proceeds  of
   $1,142,750.  The Series B preferred  stock is designated  as  redeemable  10%
   cumulative  non-voting  convertible preferred stock with $.001 par value. The
   shares  are  convertible  on a one for  one  basis  into  common  stock.  The
   dividends  accrue  at the  rate of $.50  per  share  per  annum  and are paid
   annually  commencing  July  15,  1999.  At  the  Company's  election,  annual
   dividends  were paid in shares of the Company's  common stock valued at $5.00
   per share at July 15, 1999.  Dividends  are added to net loss in  determining
   net loss per  common  share.  15,000  Series B  preferred  shares  have  been
   converted as of December 31, 1999. All unconverted shares will be redeemed at
   $5.00 per share on or before July 15, 2003.

5. Stockholders' equity

   Recapitalization:

   On December 9, 1997, the Company entered into an agreement and plan of merger
   with Vanden to exchange all of the issued and  outstanding  common  shares of
   the Company,  in exchange for  5,220,000  shares of Vanden's  $.001 par value
   common stock, in a reverse acquisition.

                           NOTES TO FINANCIAL STATEMENTS
                             December 31, 1998 and 1999




5. Stockholders' equity (continued)

   Pursuant to the  agreement,  Vanden  agreed to have cash of  $220,000  and no
   unpaid liabilities at the effective date of the transaction. The exchange was
   consummated  on January 15, 1998 and is presented on the statement of changes
   in stockholders'  equity as an issuance of 480,051 shares of common stock for
   cash proceeds of $220,100  pursuant to  recapitalization.  In connection with
   the  recapitalization,  the Company issued options to purchase 180,001 shares
   of its $.001 par value  common stock for cash of $100 and options to purchase
   an additional 180,001 shares of common stock for $2.80 per share, as required
   by a management  advisory services contract as compensation for arranging the
   merger. The difference between the fair value of the stock,  estimated by the
   Company to be $2.75 per share, and the purchase price for the initial 180,001
   shares was treated as  additional  cost of the merger and charged to capital,
   consistent with accounting for the reverse acquisition as a recapitalization.
   The net effect of this  transaction  was to record an  increase  and  related
   decrease to additional paid-in capital of $495,000.  The remaining options to
   acquire 180,001 shares are exercisable for a five-year period.

   Following the exchange, the Company's shareholders owned approximately 95% of
   the  outstanding  common stock of Vanden.  The reverse  acquisition  has been
   accounted  for as a  recapitalization  of the Company  based upon  historical
   cost.  Accordingly,  the number of authorized and issued common  shares,  par
   value of common stock and  additional  paid-in  capital have been restated on
   the  balance  sheet  and  the  statement  of  stockholders'  equity  to  give
   retroactive effect to the recapitalization.

   Private placements:

   In January 1998, the Company  completed a private placement of 300,000 shares
   of its $.001 par value common stock for gross proceeds of $825,000, $2.75 per
   share.

   In April 1999, the Company completed a private placement of 497,500 shares of
   its $.001 par value  common  stock at $2.00 per share for gross  proceeds  of
   $995,000.

   In June 1999,  the Company sold  304,750  shares of common stock at $4.00 per
   share for gross proceeds of $1,219,000 in a private placement.

   In September  1999,  the Company sold 406,450 shares of common stock at $4.00
   per share for gross proceeds of $1,625,800 in a private placement.

   Proposed public offering:

   In June 1999, the Company entered into a letter of intent with an underwriter
   to conduct a public offering of 2,000,000  units  (consisting of one share of
   common  stock and one  warrant to  purchase  one share of common  stock) with
   gross proceeds of approximately $12 to $14 million.  The per share price will
   be determined by mutual agreement between the Company and underwriter.

   Other issuances of common stock:

   In March 1999,  the  Company  received  cash  proceeds  aggregating  $200,000
   pursuant  to eight 10%  convertible  note  payable  agreements  with  various
   unrelated  individuals  and entities.  Each note was  unsecured,  and due the
   earlier of 90 days from the date of issue or upon the  receipt by the Company
   of certain  proceeds  from a private  offering of its  securities.  Each note
   agreement  also provided a warrant  granting the holder the right to purchase
   three and one half restricted  shares of the Company's  common stock for each
   dollar of  principal  received by the  Company,  for an  aggregate of 700,000
   shares. The warrants have certain  registration  rights, an exercise price of
   $3.00 per share and are  exercisable  for five years from the date the shares
   become freely tradable. To the extent that the shares underlying the warrants
   are not registered within two years of grant date, the holders have the right
   to exercise the warrants on a cashless  basis for a period of five years.  In
   April 1999, the Company amended the note agreements to allow the note holders
   to  convert  their  promissory  notes to shares of common  stock at $2.00 per
   share.  Upon issuing the amendment,  all note holders  converted their notes,
   including  accrued  interest,  to common stock  resulting in new issuances of
   common stock totaling 100,831 shares. Due to the immediate  conversion of the
   notes to common  stock,  none of the proceeds  received  upon issuance of the
   notes payable were  allocated to the  warrants.  The net effect of allocating
   proceeds  to the  warrants  would  be an  increase  and  corresponding  equal
   decrease in additional paid-in capital.

   Stock options and warrants:

   In April  1998,  the  Company  granted  stock  options to Western  Center for
   Clinical  Studies,  Inc. to purchase  450,000 shares of the Company's  common
   stock at $1.50 per share (see Note 7).

   In August 1998, the Company  granted to each director  options to purchase up
   to  60,000  shares  of the  Company's  common  stock  (300,000  shares in the
   aggregate), exercisable for ten years at $3.00 per share. Options to purchase
   20,000 shares each were fully vested February 1999, and the remaining  40,000
   vest on a pro rata basis monthly  through  February  2001.  Should any of the
   directors  cease to serve on the board of directors,  all non-vested  options
   shall be forfeited.  During 1999, a director resigned and options to purchase
   35,000 shares were canceled.

   In September  1998, the board of directors  approved a compensation  plan for
   three officers and directors,  to serve on a management  team, which included
   stock options in lieu of salary aggregating  295,000 shares,  exercisable for
   five years at $4.00 per share.  Options to purchase 125,000 shares were fully
   vested in December 1998 and January 1999, and the remaining 170,000 vested on
   a pro rata basis  monthly  through  June 30,  1999.  During  1999, a director
   resigned  and options to purchase  20,000  shares were  canceled.  During the
   period July through  October 1999, the Company  provided its management  team
   additional  stock  options  in lieu of salary to  purchase  an  aggregate  of
   430,000  shares of common  stock.  The options are  exercisable  at $4.00 per
   share, and were fully vested at December 31, 1999.

5. Stockholders' equity (continued)

   In October 1998, the Company  provided a 100,000 share stock option agreement
   to an organization,  with whom the Company entered into a one year consulting
   agreement.   The  consultant  provided  investor  relations  and  development
   services,  and  received  compensation  of $5,000 per month.  The options are
   exercisable  at $4.00 per share and vest 50,000  shares as of the date of the
   agreement,  25,000  shares on March 31,  1999 and  25,000  shares on June 30,
   1999.  During May and August 1999, the organization  exercised  options for a
   total of 20,000 shares of common stock. In July 1999, the Company also agreed
   to provide the  organization  with an additional  cash payment of $10,000,  a
   warrant to purchase up to an additional 23,500 shares of the Company's common
   stock,  as well as a  finder's  fee for all  funds  received  by the  Company
   related to fund raising  activities  attributable  to the  organization.  The
   warrant is exercisable for five years at $4.00 per share.

   In December  1998, the board of directors  approved a resolution  whereby the
   Company  granted to a company and an individual two stock options to purchase
   up to 17,500  shares of the  Company's  common  stock  (35,000  shares in the
   aggregate)  in exchange for services the Company  received  during 1998.  The
   options are exercisable at $4.00 per share for a period of five years and are
   fully vested as of the date of the resolution.

   On March 11,  1999,  the  Company  provided  a  175,000  share  stock  option
   agreement  to an  organization  with  whom  the  Company  entered  a one year
   consulting  agreement.  The Company may  terminate  the  agreement  after six
   months. The organization  provides  investment  community relations services,
   and receives  compensation of $3,000 per month.  The option is exercisable at
   $3.00 per  share.  The option  provides  certain  registration  rights to the
   holder,  and is exercisable the earlier of January 1, 2000 or when the shares
   become registered. The exercise period is five years from the date the shares
   become freely tradable.  To the extent that the shares underlying the options
   are not registered within two years of grant date, the holders have the right
   to exercise the options on a cashless basis for a period of five years.

   On March 15,  1999,  the  Company  provided  a 300,000  share  stock  warrant
   agreement  to an  organization,  with whom the Company  entered into an eight
   month consulting  agreement.  The organization was also to be paid a retainer
   of  $7,000  per  month.   The  organization  was  engaged  to  raise  capital
   aggregating $8 million and provide financial advisory services.  The warrants
   were exercisable at $4.50 per share. In July 1999, the Company terminated the
   consulting agreement. As final settlement,  the organization received $69,084
   for fees and expenses  earned in conjunction  with fund raising and a warrant
   to purchase 50,000 shares of the Company's common stock, exercisable for five
   years at $4.00 per share. The previous warrants to purchase 300,000 shares of
   the Company's common stock were canceled.

5. Stockholders' equity (continued)

   On March 22,  1999,  the  Company  provided  a  125,000  share  stock  option
   agreement to a  partnership,  with whom the Company  entered into a six month
   consulting agreement.  The partnership provides financial community relations
   and debt funding  services.  The options are  exercisable at $3.00 per share.
   The  options  provide  certain  registration  rights to the  holder,  and are
   exercisable  the  earlier  of  January  1,  2000 or when  the  shares  become
   registered. The exercise period is five years from the date the shares become
   freely tradable. To the extent that the shares underlying the options are not
   registered  within two years of grant  date,  the  holders  have the right to
   exercise the options on a cashless basis for a period of five years.

   On March 31,  1999,  the  Company  provided  a 300,000  share  stock  warrant
   agreement  to an  organization,  with whom the Company  entered into an eight
   month  consulting  agreement.  The  organization was engaged to raise capital
   aggregating $8 million and provide financial advisory services.  The warrants
   are exercisable at $3.00 per share,  provide certain registration rights, and
   vest  100,000  shares  as of the date of the  agreement,  with the  remaining
   200,000  shares to vest in May and August  1999,  subject to certain  funding
   requirements.  The 200,000  shares are subject to ratable  reductions  to the
   extent that any of the funding is not attributable to the  organization.  The
   term of the  warrants  will be through  March 22,  2004.  The Company had not
   received  any  funding  during  1999  attributable  to the  organization  and
   warrants  to  purchase  200,000  shares  have been  canceled.  The  remaining
   warrants to purchase 100,000 shares are in dispute.

   In June 1999, the Company  provided a 60,000 share stock option  agreement to
   an individual providing  intellectual  property assistance and advice related
   to the Company's  technology  and products.  The options are  exercisable  at
   $5.00 per share for five years. Options to purchase 20,000 shares vest on May
   1, 2000,  with the remaining  shares vesting  ratably  monthly through May 1,
   2002.

   In June 1999, the Company  provided a 20,000 share stock option  agreement to
   an officer in exchange for services rendered to the Company.  The options are
   exercisable at $4.00 per share for five years.  The options vest ratably over
   a 12 month period from date of grant.

   In  June  and  July  1999,  the  Company  provided  stock  option  agreements
   aggregating 120,000 shares to an organization  providing financial consulting
   services.  The options are  exercisable  at $3.00 to $4.00 per share and vest
   25,400 shares as of June 30, 1999,  20,000 shares at August 5, 1999, with the
   remaining shares vesting through February 1, 2001.

   In  September  1999,  the  Company  provided a 101,681  share  stock  warrant
   agreement to an organization  providing  assistance in the June and September
   1999 private  placements of common  stock.  The warrants are  exercisable  at
   $4.00 per share for five years and are fully vested.

   In November  1999, as partial  consideration  for  consulting  services,  the
   Company issued to a consultant a warrant to purchase  30,000 shares of common
   stock, exercisable at $4.00 per share for five years.

5. Stockholders' equity (continued)

   Also in  November  1999,  the Company  granted an option to purchase  400,000
   shares of common  stock to its  president  at an exercise  price of $5.00 per
   share.  The shares vest as follows:  100,000  shares upon  completion  of the
   first part of the Phase III trials; 150,000 shares upon submission of the New
   Drug  Application  (NDA);  and,  150,000 shares upon approval of the NDA. The
   options expire five years from the dates they become exercisable.

5. Stockholders' equity (continued)

   At December 31, 1999,  outstanding options and warrants aggregating 1,565,182
   shares have certain  registration rights and options and warrants aggregating
   2,295,181 shares contain certain cashless exercise provisions.

   4,114,564 shares of  the 4,179,564 shares owned  by  the Company's directors,
   officers, and 5% or greater stockholders, and substantially all of the shares
   underlying  the  outstanding  options  and  warrants  are  subject to lock-up
   agreements  which  expire one year after  the effective date of  the proposed
   public offering unless released sooner upon written consent.

   Unearned stock compensation:

   At December 31, 1999,  the Company had  outstanding an aggregate of 3,621,182
   options and warrants of which 2,436,000 were granted at purchase prices lower
   than fair value of the stock at date of grant,  including  the stock  options
   and warrants  disclosed  above and the 450,000  granted to the Western Center
   for Clinical Studies, Inc. (see Note 7).  The excess of the fair value at the
   grant date of the  options and  warrants,  over the  exercise  price has been
   recorded as  additional  paid-in  capital and  unearned  stock  compensation.
   Unearned  compensation  is being  amortized to research and  development  and
   general and administrative  expense over the term of the related  agreements,
   as follows:

                                               Year ended         Cumulative

                                        ==========  ==========   ==========


   The fair value of each option and warrant  grant is  estimated on the date of
   grant  using  the  Black-Scholes  option  pricing  model  with the  following
   assumptions used for grants in 1998 and 1999:  dividend yield of 0%, expected
   volatility  of 51% - 100%,  risk-free  interest  rate of 4.63% -  6.22%,  and
   expected life of five to nine years.

6. Basic and diluted net loss per share

   Basic net loss per share is based on the  weighted  average  number of shares
   outstanding during the periods.  Shares issued for nominal  consideration are
   considered  outstanding  since  inception.  Diluted  loss per share  excludes
   dilution from common stock equivalents,  as exercise of the outstanding stock
   options and warrants would have an anti-dilutive  effect.  The 10% cumulative
   dividends on Series B preferred stock have been accrued and added to net loss
   for the purpose of determining net loss and net loss per share  applicable to
   common shareholders.

7. Commitments and contingencies

   Compensation agreements:

   In 1993,  the Company  entered  into a 30 year  compensation  agreement  with
   I.B.C. limited partners owning 64.28% of the I.B.C. Limited Partnership.  The
   limited  partnership  participated  in the early  development  of  Esterom(R)
   solution (the  medicine) and owned the patent rights to three patents and all
   intellectual  property rights. Under the terms of the Agreement,  the Company
   acquired all of the patent and  intellectual  property rights in exchange for
   certain  compensation  to the limited  partners,  which is dependent upon the
   Company's  receipt  of a  marketing  partner's  technological  access fee and
   royalty  payments.  The  limited  partnership  was  subsequently   dissolved.
   Compensation  under the  agreement  includes a bonus payment of $96,420 to be
   paid at the  time  the  Company  is  reimbursed  by a drug  company  for past
   expenses  paid  for  development  of the  medicine,  as well as  64.28%  of a
   decreasing payment rate (3% to 1%) on cumulative annual royalties received by
   the Company.  As of December 31, 1999, no liabilities  have been accrued with
   respect to this agreement.

   In a separate  agreement with certain  former I.B.C.  limited  partners,  the
   Company has agreed to pay the partners 35.72% of a decreasing  earned payment
   (3% to 1% on  cumulative  annual  sales of  products  by the  Company)  until
   October 10, 2004.  From October 10, 2004 until October 10, 2014,  the Company
   will pay the partners  17.86% of the earned  payment.  In accordance with the
   agreement,  the Company has agreed to pay these former  limited  partners the
   amount of $40,000 and a minimum earned payment of $3,572 per calendar quarter
   beginning on December 1, 1989.  Such minimum  earned  payment is payable when
   the Company is either reimbursed for expenses paid for the development of the
   medicine or from the first  income  received by the Company from net sales of
   the  medicine.  The quarterly  payments are to be applied  against the earned
   payment to be received by the limited partners.  As of December 31, 1999, the
   liability  accrued  with  respect to this  agreement  totaled  $184,071.  The
   Company  will receive a credit  against the earned  payments of 50% of monies
   which are expended in  connection  with  preparing,  filing,  obtaining,  and
   maintaining patents involved with the sold rights.

   Development and Supply Agreements:

   On January 1, 1997, the Company entered into ten year  Development and Supply
   Agreements  with  Mallinckrodt,   Inc.  to  develop  all  of  the  chemistry,
   manufacturing  and  controls  to comply with the drug master file of the Food
   and Drug  Administration  as well as  supply  the  bulk  active  product  for
   marketing.  In exchange for these services,  Mallinckrodt  received exclusive
   rights as a  supplier  of the bulk  active  product  to the  Company in North
   America.  The price of the ingredient is based on the price of the components
   in the bulk active product.

   In addition, pursuant to the agreements, the Company has granted Mallinckrodt
   a right of first  refusal to supply the  Company's  requirements  of the bulk
   active product in all other parts of the world outside of North America.

7. Commitments and contingencies (continued)

   The Company is dependent upon Mallinckrodt,  Inc. to provide the raw material
   from which the active ingredients in Esterom(R) solution are derived.

   License Agreement:

   In January 1998, the Company entered into an agreement with a director of the
   Company,  whereby the Company granted the director a  non-exclusive  right to
   make, import and use the Company's product,  Esterom(R)  solution,  under the
   Company's licensed patents and to use the Company's confidential  information
   to  develop  new  products  that  contain  the  same  active  ingredients  as
   Esterom(R)  solution,  but are  formulated  differently.  All  rights  to the
   improved  products will remain the exclusive  property of the Company and the
   director will receive a two percent  royalty on the net sales of all improved
   products,  and a negotiated  royalty on new products.  The expiration date of
   this agreement is January 1, 2003.

   Management agreements:

   During  April  1998,  the  Company  entered  into  an agreement  with Western
   Center for Clinical  Studies,  Inc. (WCCS),  to provide  assistance in taking
   Esterom(R) solution through the clinical trials and New Drug Application(NDA)
   approval.  The  agreement was  subsequently  amended in July 1999 and October
   1999.  The  Company is required to pay  management  fees of $880,400  through
   January  5,  2001  and  $76,400  per  quarter  commencing  January  2001  and
   continuing  until NDA submission.  The Company also has granted stock options
   to WCCS to  purchase  450,000  shares of Entropin  common  stock at $1.50 per
   share.  The  options  will  expire  five  years  from  the date  they  become
   exercisable. The shares underlying the options are also provided with certain
   registration  rights. The difference between the fair value of the options at
   date of grant and the exercise price, totaling approximately $1,950,000 using
   the  Black-Scholes  option  pricing  model,  has been  recorded as additional
   paid-in  capital  and  unearned  stock   compensation.   The  unearned  stock
   compensation is being amortized to expense on a straight-line  basis over the
   initial 33 month term of the agreement.

   In August  1999,  the Company  entered  into an  agreement  with  Therapeutic
   Management,  Inc. to provide clinical trial  management  services and monitor
   all aspects of Esterom(R)  solution's Phase III clinical studies. In November
   1999, the Company entered into an agreement with WCCS to assume the Company's
   obligations under Therapeutic Management Agreement. The Company will pay WCCS
   approximately $350,000 based upon completion of certain project goals.

8. Financial instruments

   The  carrying  values  of cash and cash  equivalents,  accounts  payable  and
   accounts  payable  -  related  party  approximates  fair  value  due  to  the
   short-term maturities of these instruments.

   The Company believes that it is not practical to estimate a fair market value
   different  from  the  carrying  value  of  long-term  debt.  Long-term  debt,
   excluding  the deferred  royalty  agreement,  was converted  into  redeemable
   preferred stock on January 15, 1998. Both the redeemable  preferred stock and
   the  deferred  royalty  agreement  have  numerous  features  unique  to these
   securities and agreements as described in Notes 4 and 7.
