             HALSEY DRUG CO., INC. ANNOUNCES RESULTS OF 2004 ANNUAL
                  MEETING AND COMPLETION OF ASSET SALE TO IVAX

                   CHANGES NAME TO ACURA PHARMACEUTICALS, INC.

PALATINE,  IL,  AUGUST 13,  2004:  Halsey  Drug Co.,  Inc.  (OTC.BB-HDGC)  today
announced that  Shareholders at its 2004 Annual Meeting  authorized an amendment
to the Company's charter to change its name to Acura  Pharmaceuticals,  Inc. The
new name becomes  effective today. As a result of this name change,  the Company
will  receive a new stock symbol and will notify the market of the new symbol as
soon as it is provided by NASDAQ.

In addition to changing the Company's  name the  Shareholders  approved  certain
additional matters including:

o        Elected six directors to the board;

o        Authorized  the Company to amend its  Certificate of  Incorporation  to
         increase the number of authorized  shares of its $0.01 par value common
         stock to 650.0  million  shares  and to  authorize  various  series  of
         preferred stock;

o        Approved the sale of substantially all the assets used in the Company's

         December 31, 2004.

Commenting, Andy Reddick, President and CEO said, "We're pleased to announce the
name change to Acura Pharmaceuticals,  Inc. Our new name closes a chapter on the
Company's  heritage as a  manufacturer  of generic  pharmaceutical  products and
clearly  signifies  the  establishment  of a  revitalized  organization  engaged
primarily  in research,  development  and  manufacture  of  proprietary  product
candidates   utilizing  our  innovative   opioid  abuse  deterrent   formulation
technology.  These are truly  exciting times as we attempt to fill a market void
for products designed to deter abuse of orally administered opioids.

The additional matters approved at the 2004 Annual Meeting serve to further the corporate restructuring begun in late 2003 by allowing for the completion on August 13, 2004 of the sale of the Company's former generic manufacturing facilities located in Congers, New York to IVAX Pharmaceuticals New York LLC. The asset sale was completed in accordance with the terms of the Asset Purchase Agreement dated March 19, 2004 previously disclosed on Form 8-K, and provided for a cash payment to the Company of $2.5 million. Of this amount, $2.0 million was received on March 19, 2004 and the remaining $0.5 million was received August 13, 2004. In addition, the approval of the amendment to the Company's Certificate of Incorporation triggers the immediate conversion of all of the Company's outstanding convertible debentures totaling approximately $100.6 million into approximately 218.0 million shares of convertible preferred stock. Such preferred stock is convertible into an aggregate of approximately 305.8 million shares of the Company's common stock." Acura Pharmaceuticals, Inc. (formerly Halsey Drug Co., Inc.), together with its subsidiaries, is an emerging pharmaceutical technology development Company specializing in proprietary opioid abuse deterrent formulation technology and opioid API synthesis technologies.
