Item 2.  Acquisition or Disposition of Assets

a.  On May 7, 1997, Dura Pharmaceuticals, Inc. (the "Company") acquired from 
Syntex (USA) Inc., and other members of the Roche Group ("Syntex"), U.S. 
rights to the intranasal steroid products Nasarel-Registered Trademark- and 
Nasalide-Registered Trademark- (flunisolide).  The purchase price consisted 
of $70.0 million paid in cash at closing.  Additional future contingent 
payments totaling  $15.0 million are due from December 1997 through December 
1998, subject to the products remaining without a competing nasal formulation 
of flunisolide.

The Nasalide-Registered Trademark- and Nasarel-Registered Trademark- products
generated combined U.S. sales for Syntex in 1994, 1995, and 1996 of
approximately $22.3 million, $16.9 and $20.5 million, respectively, and direct
product cost of sales in 1994, 1995, and 1996 of approximately $1.6 million,
$863,000, and $944,000, respectively.

Nasalide-Registered Trademark- and Nasarel-Registered Trademark- products will
be marketed by the Company's national sales force to respiratory physicians. The
Company expects to increase the number of its field sales force personnel to
support the addition of  Nasalide-Registered Trademark- and Nasarel-Registered
Trademark- to its product line.

The Company has entered into agreements with third parties for their 
manufacture and supply of the active ingredient and finished dosage forms 
related to both products. The Company does not expect these manufacturing and 
supply agreements to significantly impact the products' future cost of sales 
as a percent of sales as compared to historical percentages.


Item 7.  Financial Statements and Exhibits

b.  Pro Forma Financial Information:

The following pro forma balance sheet of the Company as of March 31, 1997 
adjusts the financial position of the Company as if the acquisition of the 
U.S. rights to Nasalide-Registered Trademark- and Nasarel-Registered 
Trademark- had taken place as of that date.  The pro forma statements of 
operations for the year ended December 31, 1996 and for the three months 
ended March 31, 1997 combine the operations of the Company and the current 
acquisition of the U.S. rights to Nasalide-Registered Trademark- and 
Nasarel-Registered Trademark- and the previously reported acquisitions of 
certain Entex-Registered Trademark-products in July 1996 and of the patented 
antibiotics Ceclor-Registered Trademark- CD and Keftab-Registered Trademark- 
in September 1996, as if the acquisitions had taken place on January 1, 1996. 
The Company's financial information included in the pro forma statement of 
operations for the year ended December 31, 1996 was previously reported in 
the Company's annual report on Form 10-K for the year ended December 31, 
1996.  The Company's historical financial information included in the pro 
forma balance sheet and the pro forma statement of operations as of and for 
the three months ended March 31, 1997 was previously reported in the 
Company's quarterly report on Form 10-Q for the three months ended March 31, 
1997.  In the opinion of management, all pro forma adjustments necessary to 
state fairly such pro forma financial information have been made.

                                          2

The pro forma  balance sheet and statements of operations should be read in 
conjunction with the notes included in this report.  The pro forma financial 
information is not necessarily indicative of what the actual financial 
results would have been had the acquisitions occurred on January 1, 1996 or 
March 31, 1997.  In addition, the pro forma financial information does not 
purport to indicate the results of future operations or financial position of 
the Company from the acquisition date forward.

c.  Exhibits:

2.1           Syntex Asset Purchase Agreement dated March 27, 1997 (the "Syntex
              Agreement") between the Company and Syntex.  The schedules
              referenced in the Syntex Agreement have not been included because
              they contain information that is not material to an investment 
              decision and is otherwise discussed in the agreement; they will  
              be provided supplementally to the Commission upon request.

2.2           SPIL Asset Purchase Agreement dated March 27, 1997  (the "SPIL
              Agreement") between the Company and Syntex Pharmaceuticals
              International Limited.  The schedules referenced in the SPIL
              Agreement have not been included because they contain 
              information that is not material to an investment
              decision and is otherwise discussed in the agreement; they will 
              be provided supplementally to the Commission upon request.

99.1          Press Release dated May 7, 1997 issued by the Company.

             DURA PHARMACEUTICALS ANNOUNCES ACQUISITION OF TWO INTRANASAL
                  STEROID PRODUCTS, NASAREL-REGISTER TRADEMARK- AND
      NASALIDE-REGISTERED TRADEMARK-, FROM SYNTEX, A MEMBER OF THE ROCHE GROUP

    SAN DIEGO, CA -- May 7, 1997 -- Dura Pharmaceuticals, Inc. (NASDAQ NNM: 
DURA) today announced that it has signed agreements to acquire the intranasal 
steroid products Nasarel-REGISTERED TRADEMARK- and Nasalide-REGISTERED 
TRADEMARK-  (flunisolide) Nasal Solutions 0.025% from Syntex (USA), Inc., a 
member of the Roche Group, for $70 million plus additional contingent payment 
amounts.  The transaction is expected to close this week.  Dura believes that 
combined first full-year sales for the two products could be $25 - $30 
million.  The market for intranasal steroids in the U.S. was approximately 
$700 million in 1996, and has averaged 24% growth over the last two years.
"Nasal steroids are emerging as an important therapy for the treatment of 
the symptoms of seasonal and perennial allergic rhinitis," said Cam Garner, 
Dura's Chairman, President and CEO.  "The Nasarel-REGISTERED TRADEMARK-  and 
Nasalide-REGISTERED TRADEMARK-  products are ideal for Dura, as they fit 
squarely within our respiratory focus and add a new respiratory category to 
our product portfolio, diversifying our offering to high-prescribing 
physicians and further leveraging our sales representatives' time in every 
sales call."
    In addition to the strategic fit of the products, Dura expects 
Nasarel-REGISTERED TRADEMARK-  and Nasalide-REGISTERED TRADEMARK-  to have 
positive financial impact. "We expect that the products will be accretive to 
earnings despite our immediate investments in sales force expansion and 
product promotion," noted Mr. Garner.    A portion of the revenues from the 
products will fund the expansion of Dura's 200-person sales force by 50 
representatives who will target respiratory specialists.  These new positions 
are in addition to the previously planned expansion to 250 representatives by 
year end, bringing the expected sales force total to 300 by the end of 1997. 
"The acquisition of Nasarel-Registered Trademark- and Nasalide-Registered 
Trademark-is expected to accelerate our plans to reach 350 representatives in 
time for the launch of the first Spirosa inhaler product, Spirosa albuterol, 
expected in late 1998," said Mr. Garner.  "The sales force expansion 
strengthens our focus on key respiratory physicians since the highest 
potential prescribers of intranasal steroids are also the highest potential 
prescribers of Spirosa-TM-."
                                        (more)

    In the transaction, Dura gains ownership of the trademarks, NDAs, patents,
licenses, and certain formulation manufacturing know-how associated with each
product, as well as the right to develop and market the products
over-the-counter.  The patent life of the active ingredient in the two 
products, flunisolide hemihydrate, extends into 2007. "This agreement is a 
natural strategic move for both companies," said Stephen G. Sudovar, Senior 
Vice President, Pharmaceuticals for Roche Laboratories.  "Dura is gaining two 
excellent respiratory pharmaceuticals, and Roche will continue to focus on 
our strategic strengths."
    Dura Pharmaceuticals is a San Diego-based developer and marketer of
prescription pharmaceutical products for the treatment of allergies, asthma and
related respiratory conditions, and is developing a pulmonary drug delivery
system. Dura's mission is to be the leading niche pharmaceutical company with a
focus in the high-growth U.S. respiratory market.  The Company is pursuing that
goal through two major strategies:  (1) acquiring late-stage prescription
pharmaceuticals and/or companies with rights to such pharmaceuticals for
marketing to high-prescribing respiratory physicians and (2) developing Spirosa,
a proprietary dry powder pulmonary drug delivery system.

which involve risks and uncertainties, including the timely development of the
Spiros-TM- system, competitive products and pricing, the ability of the Company 
to acquire products and/or companies, the Company's limited manufacturing 
experience, seasonality, and other risks detailed from time to time in the 
Company's filings with the Securities and Exchange Commission.  Actual 
results may differ materially from those projected.  These forward-looking 
statements represent the Company's judgment as of the date of this release.  
The Company disclaims, however, any intent or obligation to update these
