RECENT DEVELOPMENTS
                                
During November 1996, Dr. Bernard B. Levine resigned from the
Board of Directors of Cypros Pharmaceutical Corporation (the
"Company") and was replaced by Mr. Robert F. Allnutt.

THE COMPANY

The Company was founded in California in 1990 and is engaged in
the development and marketing of drug products for the hospital
market. It is currently marketing three injectable products and
is developing two small molecule therapeutic drugs, CPC-111 and
CPC-211, for the treatment of disorders, such as stroke,
traumatic head injury, congestive heart failure, cardiac surgery,
sickle cell crisis, and the acute complications of angioplasty,
all of which are characterized by ischemia (impaired blood flow),
which interrupts the delivery of both glucose and oxygen to
tissue. The Company's executive offices are located at 2714 Loker
Avenue West, Carlsbad, California 92008, and its telephone number
is (619) 929-9500.

RISK FACTORS

Except for the historical information contained herein, the
discussion in this Prospectus contains forward-looking statements
that involve risks and uncertainties. The Company's actual
results could differ materially from those discussed here.
Factors that could cause or contribute to such differences
include, but are not limited to, those discussed in the following
risk factors as well as those discussed elsewhere in this
Prospectus and any documents incorporated herein by reference.

The following factors, in addition to those discussed elsewhere
in this Prospectus, or incorporated herein by reference, should
be carefully considered in evaluating the Company and its
business.

Continuing Operating Losses

The Company reported a net loss of $3,090,108 or $0.27 per share
for the fiscal year ended July 31, 1996 compared to a loss of
$3,112,701 or $0.32 per share for the prior year. The Company
expects that it will continue to incur operating losses as it
increases expenditures for clinical testing, Investigational New
Drug Application and New Drug Application filings and other
regulatory activities, U.S. patent prosecution, and product
acquisition and sales and marketing activities.  To achieve
profitable operations, the Company, alone or with others, must
successfully develop, obtain regulatory approval for, introduce,
acquire, market and sell additional products. There can be no
assurance that the Company's product acquisition and development
efforts will result in additional products, that required
regulatory approvals will be obtained with respect to all or any
of its products now under development or that any of these
products will be commercially successful.

Significant Capital Requirements; Need for Additional Financing

The  development  and  commercialization of  drugs  requires  the
commitment  of  significant  capital expenditures.   The  Company
believes  that existing capital resources and the cash flow  from
its  recently-acquired products will allow  it  to  maintain  its
current  and  planned  operations for  at  least  two  years.  In
addition  to  funds  provided  from exercises  of  its  currently
outstanding  Redeemable Class B Warrants  (the  "Warrants"),  the
Company  is seeking to obtain additional funds through public  or
private  equity  financings, collaborative or other  arrangements
with  corporate partners or from other sources.  There can be  no
assurance  that  such additional financing  can  be  obtained  on
desirable  terms  or  at  all.   If  additional  funds  are   not
available,  the Company may be required to curtail  significantly
or   eliminate  one  or  more  of  its  research,  discovery   or
development  programs or obtain funds through arrangements  which
may  require the Company to relinquish rights to certain  of  its
products.

Uncertainties Associated with Regulatory Approval

A   marketed   drug,  its  manufacturer  and  its   manufacturing
facilities   are  subject  to  continual  review   and   periodic
inspections,  and later discovery of previously unknown  problems
with   a   product,  manufacturer  or  facility  may  result   in
restrictions  on  such  product  or  manufacturers,  including  a
withdrawal of the product from the market. Failure to comply with
the  applicable regulatory requirements can, among other  things,
result  in  fines,  suspensions of regulatory approvals,  product
recalls,   operating   restrictions  and  criminal   prosecution.
Further,  additional  government regulation  may  be  established
which  could  suspend  or  revoke  regulatory  approval  of   the
Company's products.

Unproven Products

In  addition to its three approved drugs, the Company  has  other
products  in various stages of development which are  subject  to
the  risks  inherent  in drug development,  including  unforeseen
problems,   delays,   expenses   and   complications   frequently
encountered  with the early phases of research,  development  and
commercialization of products, the dependence on and attempts  to
apply  new  and  rapidly changing technology and the  competitive
environment  of  the  pharmaceutical  industry.   Many  of  these
factors   may   be   beyond  the  Company's  control,   such   as
unanticipated   development  requirements,  testing,   regulatory
compliance and manufacturing, production, and marketing  problems
and  expenses.   The Company does not anticipate  being  able  to
complete the development of its proposed products for a number of
years,  if  at  all. All of the Company's drugs  are  subject  to
extensive  regulation  and  those  in  development  will  require
approval  from the U.S. Food and Drug Administration (the  "FDA")
and  other  regulatory agencies prior to commercial  sales.   The
Company  may  not  complete the testing and  regulatory  approval
process for any of its products in development in the foreseeable
future  and, accordingly, is unable to predict whether they  will
be  commercially successful.  Further, there can be no  assurance
that the Company's drugs under development will attain acceptance
by providers, payors or patients.

Patents, Proprietary Technology and Licenses

The  Company's  success is dependent in large  measure  upon  its
ability  to  obtain  patent protection for  its  drugs,  maintain
confidentiality  of  its trade secrets and know-how  and  operate
without  infringing upon the proprietary rights of third parties.
The  Company  has licensed rights to five U.S. patents  from  the
holders of the patents on CPC-111 and CPC-211, but each of  these
licenses may be terminated in the event that the Company fails to
achieve   certain   milestones  or   accomplish   certain   other
contractual obligations. Upon any such termination,  all  of  the
Company's rights would revert to the licensor. The termination of
the  license  covering CPC-111 or CPC-211 would have  a  material
adverse  effect  on the Company and would cause  the  Company  to
focus  its  efforts  on  its remaining drug development  programs
which are not as far advanced. There can be no assurance that the
Company  will  maintain  the  licenses  in  effect  through   the
successful development and commercialization of these drugs.

The  U.S.  patent  position of pharmaceutical companies  involves
many complex legal and technical issues and has recently been the
subject   of   much  litigation.   There  is  no   clear   policy
establishing  the breadth of claims or the degree  of  protection
afforded  under  such  patents.  As a result,  there  can  be  no
assurance  that  any  of  the U.S. patent  applications  will  be
approved,  except where claims under an application have  already
been  examined  and  allowed, nor that the Company  will  develop
additional proprietary products that are patentable.   There  can
be  no  assurance that any U.S. patents issued to the Company  or
its  licensors  will  provide the Company  with  any  competitive
advantages or will not be challenged by any third parties or that
patents issued to others will not have an adverse effect  on  the
ability of the Company to conduct its business.

Furthermore, because patent applications in the United States are
maintained  in  secrecy until issue, and because  publication  of
discoveries  in  the scientific and patent literature  often  lag
behind actual discoveries, the Company cannot be certain that  it
was  the first chronologically to make the inventions covered  by
each  of its pending patent applications or that it was the first
to  file  patent applications for such inventions.  In the  event
that a third party has also filed a patent application for any of
its   inventions,  the  Company  may  have  to   participate   in
interference proceedings declared by the United States Patent and
Trademark  Office  to determine priority of the invention,  which
could  result  in substantial cost to the Company,  even  if  the
eventual outcome is favorable to the Company.  In addition, there
can  be no assurance that the Company's patents, including  those
of  the licensors above, would be held valid by a court of law of
competent jurisdiction.  If patents are issued to other companies
that  contain competitive or conflicting claims which  ultimately
may be determined to be valid, there can be no assurance that the
Company  would be able to obtain a license to any of  these  U.S.
patents.

Under  Title  35  of the United States Code, as  amended  by  the
General  Agreement on Tariffs and Trade implementing the  Uruguay
Round  Agreement  Act of 1994 ("GATT"), patents that  issue  from
patent applications filed prior to June 8, 1995, will have a  17-
year period of enforceability as measured from the date of patent
issue  while those that issue from applications filed on or after
June  8,  1995  will  have a 20-year period of enforceability  as
measured  from the date the patent application was filed  or  the
first  claimed priority date, whichever is earlier. Patents  that
issue  from applications filed on or after June 8, 1995,  may  be
extended under the term extension provisions of GATT for a period
up  to  five years to compensate for any period of enforceability
lost  due to interference proceedings, government secrecy  orders
or appeals to the Board of Patent Appeals or the Federal Circuit.

Under the Drug Price Competition and Patent Term Restoration  Act
of 1984, including amendments implemented under GATT (the "Patent
Term  Restoration Act"), the period of enforceability of a  first
or  basic  product patent or use patent covering a  drug  may  be
extended for up to five years to compensate the patent holder for
the  time required for FDA regulatory review of the product. This
law  also establishes a period of time following FDA approval  of
certain drug applications during which the FDA may not accept  or
approve  applications for similar or identical drugs  from  other
sponsors. Any extension under the Patent Term Restoration Act and
any  extension  under  GATT  are  cumulative.  There  can  be  no
assurance that the Company will be able to take advantage of such
patent  term  extensions or marketing exclusivity  provisions  of
these laws. While the Company cannot predict the effect that such
changes  will have on its business, the adoption of such  changes
could have a material adverse effect on the Company's ability  to
protect  its  proprietary information and sustain the  commercial
viability  of  its  products.  Furthermore,  the  possibility  of
shorter terms of patent protection, combined with the lengthy FDA
review  process  and  possibility of  extensive  delays  in  such
process, could effectively further reduce the term during which a
marketed product could be protected by patents.

The  Company  also relies on trade secrets and proprietary  know-
how.   The  Company has been and will continue to be required  to
disclose its trade secrets and proprietary know-how not  only  to
employees  and  consultants,  but  also  to  potential  corporate
partners, collaborators and contract manufacturers.  Although the
Company seeks to protect its trade secrets and proprietary  know-
how,  in  part  by entering into confidentiality agreements  with
such  persons  or organizations, there can be no  assurance  that
these  agreements  will not be breached, that the  Company  would
have adequate remedies for any breach or that the Company's trade
secrets  will  not  otherwise become known  or  be  independently
discovered by competitors.

Dependence on Others for Manufacture

The Company currently does not have any capability to manufacture
products  under current good manufacturing practices ("cGMP")  as
required  by  the FDA.  It relies on third parties to manufacture
and formulate Ethamolin, Glofil and Inulin and to manufacture and
formulate  CPC-111 and CPC-211, its two drug candidates currently
in clinical trials. Although the Company believes that it will be
able  to contract with alternative suppliers for its products  if
its  current suppliers are unable to supply the Company with  its
needs  for  bulk and formulated drugs, there can be no  assurance
that  this  will  be the case or that the need to  contract  with
additional suppliers will not delay the Company's ability to have
its  products manufactured. There can be no assurance that  these
manufacturers  will  meet either the Company's  requirements  for
quality,  quantity and timeliness or the FDA's cGMP  requirements
or   that  the  Company  would  be  able  to  find  a  substitute
manufacturer for any of its products in the future.  In the event
that   the  Company  is  unable  to  obtain  or  retain  contract
manufacturers  that  can  manufacture  its  products  under  cGMP
requirements,   or  to  obtain  manufacturing   on   commercially
acceptable  terms,  it  may  not be  able  to  commercialize  its
products as planned.

Potential Claims

Certain  members  of  the  Company's  Scientific  Advisory  Board
("SAB")  and  certain  Scientific  Advisors  who  have  developed
technology  used  for  the Company's products  are  employees  of
universities,  research  hospitals or  other  institutions.   The
Company believes that such institutions have no claim to  any  of
the  Company's inventions, technology or products. While no claim
has  been  asserted  by any such institution,  there  can  be  no
assurance that such institutions will not assert claims to any or
all  of  such inventions, technology or products or that, if  any
such  institution does assert such rights, the Company, if it  so
desires,  will  be able to acquire the rights thereto  from  such
institution at a commercially practical cost or at all.

Government Regulation

The  Company's development, manufacture and sale of drug products
are  subject  to  extensive and rigorous regulation  by  federal,
state, local and foreign governmental authorities. In particular,
products  for human health are subject to substantial preclinical
and  clinical testing and other approval requirements by the  FDA
and  comparable foreign regulatory authorities.  The process  for
obtaining  the  required regulatory approvals from  the  FDA  and
other  regulatory  authorities  takes  many  years  and  is  very
expensive.  There can be no assurance that any drug developed  by
the Company will prove to meet all of the applicable standards to
receive  marketing approval.  There can be no assurance that  any
such  approvals  will be granted on a timely basis,  if  at  all.
Delays  in and costs of obtaining these approvals could adversely
affect  the Company's ability to commercialize its drugs  and  to
generate significant sales revenues.  If regulatory approval of a
drug  is  obtained,  such approval may involve  restrictions  and
limitations on the use of the drug.

Other  conditions  for  an  approval  are  based  on  the  drug's
manufacture and the quality control procedures in place, such  as
cGMP.  Failure to insure compliance with cGMP requirements  could
result  in  delay or termination of clinical trials or withdrawal
of an approval. Following market approval, the drug will continue
to be subject to compliance with applicable federal, state, local
and  foreign laws and regulations. There can be no assurance that
the  FDA will grant approval of any of the Company's drugs  in  a
timely manner or at all.
Governmental  Reforms

Health  care  reform  is  an  area  of  increasing  national  and
international attention and a priority of many elected  officials
in  the  United States. Several proposals to modify  the  current
health  care  system in the United States to improve  access  and
control costs are currently being considered by federal and state
governments.  It is uncertain what legislation, if any,  will  be
adopted or what actions governmental or private payors for health
care  goods  and  services may take in response  to  proposed  or
actual  legislation  in the United States.   The  Company  cannot
predict the outcome of health care reform proposals or the effect
such reforms may have on its business.

Clinical Trial and Product Liability Claims and Uninsured Risks

The  Company  may  be  exposed to liability  resulting  from  the
conduct  of  its  clinical trials or the commercial  use  of  its
drugs.  Such liability might result from claims made directly  by
patients,   hospitals,   clinics  or  other   consumers   or   by
pharmaceutical companies or others manufacturing  such  drugs  on
behalf of the Company.  The Company currently has clinical  trial
and  product  liability insurance, but there can be no  assurance
that   it  will  be  adequate  to  protect  the  Company  against
liability.

Competition and Technological Change

The products that the Company is marketing and the drugs that the
Company is developing may compete for market share with alternate
therapies.  A number of companies are pursuing the development of
novel  pharmaceuticals  which target the  same  diseases  as  the
Company   is   targeting.    Many  of  these   competitors   have
substantially greater capital resources, research and development
staffs  and  facilities than the Company.  They may  develop  and
introduce  products and processes competitive with those  of  the
Company.   They  represent significant long-term competition  for
the  Company.  For certain of the Company's drugs,  an  important
factor in competition may be the timing of market introduction of
these  competitive products.  This timing will be  based  on  the
effectiveness  with  which the Company  or  the  competition  can
complete  clinical  trials  and  approval  processes  and  supply
quantities  of  these  products  to  market.   Competition  among
products approved for sale will be based on, among other  things,
efficacy,  safety, reliability, price, marketing  capability  and
patent position.

The  pharmaceutical industry has undergone rapid and  significant
technological changes. The Company expects that the  technologies
associated  with  its research and development will  continue  to
develop rapidly.  There can be no assurance that the Company will
be  able  to  establish itself in such fields or, if established,
that  it  will  be  able  to  maintain  a  competitive  position.
Further, there can be no assurance that the development by others
of  new  or  improved processes or products  will  not  make  the
Company's  products  and processes, if any, less  competitive  or
obsolete.

Dependence on Key Personnel

The  Company's success also depends in large part on its  ability
to  attract  and retain other qualified scientific and management
personnel.  The Company faces competition for such  persons  from
other  companies, academic institutions, government entities  and
other  organizations.  There can be no assurance that the Company
will  be successful in recruiting or retaining personnel  of  the
requisite caliber or in adequate numbers to enable it to  conduct
its  business  as  proposed. Furthermore, the Company's  expected
expansion  into  activities  requiring  additional  expertise  in
manufacturing,  sales and marketing will place increased  demands
on the Company's resources and management skills.

Limited Sales and Marketing Capability

The commercialization of products such as the Company's drugs  is
an  expensive and time-consuming enterprise.  The Company now has
sixhas  no  experience in sales, marketing or  distributio  sales
representatives for Ethamolin, Glofil and Inulin and  intends  to
hire  additional sales representatives as sales of those products
increase  and/or other products are acquired by the Company.   To
market  any of its drugs directly, the Company expects to develop
a   marketing  and  sales  force  with  technical  expertise  and
supporting distribution capability.  The Company believes that it
will be able to serve the hospital market in North America do  so
with  a  50  to 100 person sales and marketing staff.  since  its
drugs  will  be sold primarily to and administered in acute  care
facilities  rather than sold directly to physicians'  offices  or
retail  drug  stores. There can be no assurance that the  Company
will  be  able  to establish successfully sales and  distribution
capabilities  or be successful in gaining market  acceptance  for
its drugs or to obtain the assistance of any other pharmaceutical
company in these efforts if it should seek assistance.

Reimbursement

In  both  domestic  and foreign markets, sales of  the  Company's
products  will  be  dependent  in part  on  the  availability  of
reimbursement  from third party payors, such  as  government  and
private  insurance  plans.  Third party payors  are  increasingly
challenging the prices charged for medical products and services.
There  can  be no assurance that the Company's products  will  be
considered  cost-effective, that reimbursement will be  available
or,  if  available, that the payor's reimbursement policies  will
not  adversely affect the Company's ability to sell its  products
profitably.

Employee Directors' Stock Option Plan.   Holders of warrants  and
options are likely to exercise them when, in all likelihood,  the
Company  could obtain additional capital on terms more  favorable
than  those provided by the warrants and options.  Further, while
the  warrants  and  options are outstanding, they  may  adversely
affect  the  terms  on which the Company could obtain  additional
capital.

Potential Volatility of Stock Price

There  has  been  significant volatility in the market  price  of
securities of biomedical companies in general.  Announcements  of
technological  innovations  or new  commercial  products  by  the
Company  or  its competitors, developments concerning proprietary
rights,  clinical trial results, government policy or regulation,
relations  with  licensors or other corporate  partners,  general
market  conditions  or  public  concern  as  to  the  safety   of
biomedical products and period to period fluctuations in revenues
and  financial  results  may  have a significant  impact  on  the
Company's  business  and  on the market price  of  the  Company's
securities.

Dividends Not Likely

The  Company has not paid any cash dividends on its Common Stock.
For  the  foreseeable future it is anticipated that earnings,  if
any, which may be generated from the Company's operations will be
used to finance the growth of the Company and that cash dividends
will not be paid to holders of Common Stock.

SELLING SHAREHOLDERS

The  following  table  sets  forth certain information  regarding  the

(1)  On July 31, 1996, Cameron Capital, Ltd. ("Cameron")
purchased a mandatorily  convertible note from the Company in the
principal amount of $5,000,000 with a   maturity of July 31, 1999
(the "Note"). The principal amount of the Note (or portions
thereof in minimum amounts of $100,000) is convertible beginning
January 31, 1997, and the remaining principal amount of the Note
will be automatically converted (if not converted in full before
then) on July 31, 1999. The conversion rate is not fixed. Rather,
when converted, the principal amount being converted will convert
at a discount from the 10-day average of the closing bid prices
for the Company's Common Stock preceding the conversion date,
ranging from 15% on January 31, 1997 to 25% on July 31, 1997 and
thereafter.  The Note further provides that the maximum
permissible conversion price of the Note is $8.00 per share and
prohibits Cameron from converting principal amounts of the Note
into Common Stock if such conversion would result in Cameron
owning at any one time more than 5.0% of the Company's
outstanding shares of Common Stock.

In anticipation of the first date that Cameron can convert the
Note, the Company is registering herein a certain amount of
shares issuable upon conversion of the Note, which amount may be
increased or decreased over time by means of an amendment to this
registration statement. For SEC purposes, the number of shares
listed above as beneficially owned by Cameron assumes conversion
based on a 15% discount from a 10-day average closing  bid price
of $4.00 per share. Of this amount, the Company is registering
47.6% of such shares of Common Stock. However, the filing of this
registration statement is not intended to reflect any obligation
of Cameron to convert all or any portion of the Note on January
31, 1997.

(2)  Shares issuable upon exercise of a warrant issued to
Fahnestock & Co. Inc. ("Fahnestock") in consideration of
financial consulting advice provided to the Company from time to
time relating to potential strategic alliances, licenses, mergers
and acquisitions. The warrant has an exercise price of $6.26 per
share and expires January 31, 2001.

PLAN OF DISTRIBUTION

The  Company  has been advised that the Selling Shareholders  may
sell Shares from time to time, as market conditions permit on the
NASDAQ  National  Market System, or otherwise,  through  ordinary
brokerage  transactions,  in negotiated  transactions,  at  fixed
prices  which may be changed, at market prices prevailing at  the
time  of sale, at prices related to such prevailing market prices
or  at  negotiated prices.  The Selling Shareholders  may  effect
such  transactions  by selling the Shares to or  through  broker-
dealers, and all such broker-dealers may receive compensation  in
the  form  of  discounts,  concessions or  commissions  from  the
Selling Shareholders and/or the purchasers of the Shares for whom
such  broker-dealers may act as agent or to  whom  they  sell  as
principal, or both (which compensation as to a particular broker-
dealer  might  be  in  excess  of  customary  commissions).   The
aforementioned methods of sale may not be all-inclusive.

Any  broker-dealer  acquiring the Shares in the  over-the-counter
market  from  the holder may sell the Shares either directly,  in
its  normal market-making activities, through or to other brokers
on  a  principal  or agency basis or to its customers.  Any  such
sales  may  be at prices then prevailing in the over-ther-counter
market, at prices related to such prevailing market prices or  at
negotiated  prices  to  its customers or a  combination  of  such
methods. The Selling Shareholders and any broker-dealers that act
in  connection with the sale of Shares hereunder may be deemed to
be  "underwriters"  within the meaning of Section  2(11)  of  the
Securities  Act; any commissions received by them and profits  on
any  resale  of  the Shares as principal might be  deemed  to  be
underwriting discounts and commissions under the Securities  Act.
Any  such  commissions, as well as other expenses of the  Selling
Shareholders and applicable transfer taxes, are payable  by  such
parties, as the case may be.

The  Company  has  agreed to indemnify the  Selling  Shareholders
against certain liabilities, including certain liabilities  under
the Securities Act of 1933, as amended.

Item 15.  Indemnification of Officers and Directors.

Under  Section  317  of  the California  Corporations  Code,  the
Registrant  is  authorized to indemnify its directors,  officers,
employees and other agents against liabilities they may incur  in
such  capacities, including liabilities under the Securities  Act
of  1933,  as amended.  The Registrant's Bylaws provide that  the
Registrant  will  indemnify its directors and executive  officers
and  may indemnify its other officers, employees and other agents
to  the full extent permitted by law.  The Bylaws further provide
that  rights, conferred under such Bylaws shall not be deemed  to
be exclusive of any other rights such persons may have or acquire
under  any  statute, any provisions of the Registrant's  Restated
Articles  of Incorporation or Bylaws, or any agreement,  vote  of
the shareholders or disinterested directors or otherwise.

In  addition, the Registrant's Restated Articles of Incorporation
provide  that to the fullest extent permitted by California  law,
the  Company's  directors  will  not  be  personally  liable  for
monetary damages for breach of the directors' fiduciary  duty  of
care to the Company and its shareholders.  This provision in  the
Restated Articles of Incorporation does not eliminate the duty of
care, and in appropriate circumstances equitable remedies such as
an  injunction or other forms of non-monetary relief would remain
available  under California law.  Each director will continue  to
be  subject  to  liability for breach of the director's  duty  of
loyalty  to  the Registrant, for acts or omissions  not  in  good
faith  or involving intentional misconduct for knowing violations
of  law,  for  actions leading to improper personal benefit,  for
acts  or  omissions  that  constitute  an  unexcused  pattern  of
inattention that amounts to an abdication of the director's  duty
to  the  Registrant  or  its  shareholders  and  for  payment  of
dividends, approvals of stock repurchases or redemptions or loans
or  guarantees  that  are unlawful under California  law.   These
provisions do not affect a director's responsibilities under  any
other  laws, such as the federal securities laws or the state  or
federal environmental laws.

There is no pending material litigation or proceeding involving a
director,  officer, employee or other agent of the Registrant  as
to  which  indemnification is being sought, nor is the Registrant
aware  of any pending or threatened material litigation that  may
result  in  claims for indemnification by any director,  officer,
employee or other agent.

Item 17.  Undertakings.

Insofar  as  indemnification for liabilities  arising  under  the
Securities  Act of 1933 may be permitted to directors,  officers,
and  controlling  persons  of  the  Registrant  pursuant  to  the
provisions described in Item 15 or otherwise, the Registrant  has
been  advised that in the opinion of the Securities and  Exchange
Commission,  such  indemnification is against  public  policy  as
expressed  in the Act and is, therefore, unenforceable.   In  the
event  that  a claim for indemnification against such liabilities
(other than the payment by the Registrant of expenses incurred or
paid  by  a  director,  officer, or  controlling  person  of  the
Registrant  in  the successful defense of any  action,  suit,  or
proceeding) is asserted by such director, officer, or controlling
person  in  connection with the securities being registered,  the
Registrant will, unless in the opinion of its counsel the  matter
has  been settled by controlling precedent, submit to a court  of
appropriate    jurisdiction    the    question    whether    such
indemnification  by it is against public policy as  expressed  in
the  Act  and will be governed by the final adjudication of  such
issue.

The undersigned Registrant hereby undertakes: (1) to file, during
any  period  in  which offers or sales are being  made,  a  post-
effective amendment to this registration statement:

(i)   to  include any prospectus required by section 10(a)(3)  of
the Securities Act of 1933;

(ii)  to  reflect in the prospectus any facts or  events  arising
after  the effective date of the registration statement  (or  the
most recent post-effective amendment thereof) which, individually
or  in  the  aggregate,  represent a fundamental  change  in  the
information   set   forth   in   the   registration    statement.
Notwithstanding the foregoing, any increase or decrease in volume
of  securities  offered (if the total dollar value of  securities
offered  would  not  exceed that which was  registered)  and  any
deviation  from  the  low or high end of  the  estimated  maximum
offering  range may be reflected in the form of prospectus  filed
with the Commission pursuant to Rule 424(b) if, in the aggregate,
the  changes  in volume and price represent no more  than  a  20%
change  in the maximum aggregate offering price set forth in  the
"Calculation   of  Registration  Fee"  table  in  the   effective
registration statement;

(iii)  to  include any material information with respect  to  the
plan   of   distribution  not  prreviously   disclosed   in   the
registration statement or any material change to such information
in the registration statement;

provided however, that clauses (i) and (ii) do not apply  if  the
information required to be included in a post-effective amendment
by  these clauses is contained in periodic reports filed  by  the
Registrant  pursuant  to  section 13  or  section  15(d)  of  the
Securities  Exchange  Act  of  1934  that  are  incorporated   by
reference  in  the  registration statement;  (2)  that,  for  the
purpose of determining any liability under the Securities Act  of
1933,  each post-effective amendment shall be deemed to be a  new
registration   statement  relating  to  the  securities   offered
therein,  and the offering of such securities at that time  shall
be  deemed to be the initial bona fide offering thereof; and  (3)
to   remove  from  registration  by  means  of  a  post-effective
amendment  any  of the securities being registered  which  remain
unsold at the termination of the offering.

The undersigned Registrant hereby undertakes: (1) for purpose  of
determining any liability under the Securities Act of  1933,  the
information omitted from the form of prospectus filed as part  of
the  registration  statement  in  reliance  upon  Rule  430A  and
contained  in  the  form of prospectus filed  by  the  Registrant
pursuant  to Rule 424(b)(1) or (4) or 497(h) under the Securities
Act  shall be deemed to be part of the registration statement  as
of  the  time it was declared effective; (2) for the  purpose  of
determining any liability under the Securities Act of 1933,  each
post-effective amendment that contains a form of prospectus shall
be  deemed  to  be a new registration statement relating  to  the
securities  offered therein, and the offering of such  securities
at that time shall be deemed to be the initial bona fide offering
thereof; and (3) for purposes of determining any liability  under
the  Securities  Act  of 1933, each filing  of  the  Registrant's
annual  report pursuant to Section 13(a) or Section 15(d) of  the
Securities  Exchange  Act of 1934  (and, where  applicable,  each
filing  of  an employee benefit plan's annual report pursuant  to
Section  15(d)  of the Securities Exchange Act of 1934)  that  is
incorporated by reference in the registration statement shall  be
deemed  to  be  a  new  registration statement  relating  to  the
securities  offered therein, and the offering of such  securities
at that time shall be deemed to be the initial bona fide offering
thereof.

Ladies and Gentlemen:

You  have requested our opinion with respect to certain matters  in
connection  with  the  filing by Cypros Pharmaceutical  Corporation
(the  "Company")  of  a Registration Statement  on  Form  S-3  (the
"Registration   Statement")  with  the  Securities   and   Exchange
Commission  covering the offer and sale of up to  an  aggregate  of
750,000  shares  of the Company's Common Stock, no  par  value,  by
certain  shareholders,  in connection with the  resale  of  700,000
shares  of  the  Company's  Common Stock (the  "Converted  Shares")
issuable  upon conversion of a Convertible Note due and payable  as
of  July  31, 1999 (the "Note") and 50,000 shares of the  Company's
Common  Stock  (the "Warrant Shares") issuable upon exercise  of  a
Warrant to Purchase Common Stock dated as of February 2, 1996 (the
"Warrant").

In  connection with this opinion, we have examined the Registration
Statement  and  related  Prospectus,  your  Restated  Articles   of
Incorporation,  as amended, your Bylaws, as amended,  the  Warrant,
the   Note,   and  such  other  documents,  records,  certificates,
memoranda and other instruments as we deem necessary as a basis for
this opinion.  We have assumed the genuineness and authenticity  of
all  documents  submitted  to us as originals,  the  conformity  to
originals  of all documents submitted to us as copies thereof,  and
the due execution and delivery of all documents where due execution
and delivery are a prerequisite to the effectiveness thereof.

On  the basis of the foregoing, and in reliance thereon, we are  of
the  opinion  that the Converted Shares, when sold  and  issued  in
accordance  with the Note, and that the Warrant Shares,  when  sold
and  issued in accordance with the Warrant, will be validly issued,
fully paid, and nonassessable.
