Barr Says Court Denies Preliminary Injunction to Halt Generic Allegra(R) Sales

Barr and Teva To Continue Marketing Fexofenadine Hydrochloride Tablets

WOODCLIFF LAKE, N.J., Jan. 27 (HSMN NewsFeed) -- Barr Pharmaceuticals, Inc. (NYSE: BRL ) today confirmed that the United States District Court for the District of New Jersey has denied a motion filed by Aventis Pharmaceuticals, Inc. and Albany Molecular Research, Inc. that would have forced Barr and Teva Pharmaceutical Industries Ltd. (Nasdaq: TEVA ) to cease marketing Fexofenadine Hydrochloride 30 mg, 60 mg and 180 mg Tablets, the generic versions of Aventis' AllegraŽ Tablets. On September 6, 2005 Barr and Teva announced that they had entered into an agreement and launched the Fexofenadine Hydrochloride Tablet products.

"We are extremely pleased that the Court decision will allow American allergy sufferers to continue to save on their Fexofenadine Hydrochloride Tablet prescription," said Bruce L. Downey, Barr's Chairman and Chief Executive Officer. "Since our September launch, consumers have realized considerable savings as a result of the competition our product has created. We will continue to defend our launch of this product as we pursue the underlying patent challenge litigation with Aventis."

Under its agreement with Teva, Barr took the regulatory steps necessary to permit Teva to obtain final U.S. Food and Drug Administration approval of Teva's Fexofenadine Hydrochloride Tablets and to sell the product within Barr's 180-day exclusivity period. Barr was the first generic applicant to file an Abbreviated New Drug Application (ANDA) containing a paragraph IV patent challenge on the patents related to the AllegraŽ tablet products and consequently was granted 180 days exclusivity, which it has now transferred to Teva.

In June 2004 Barr and Teva were granted summary judgment of non-infringement with respect to three patents, and were granted summary judgment of invalidity on an additional patent in the case in April 2005. Several patents remain in the litigation. Although no trial date has been set, the companies expect that a trial will occur sometime in 2006.

AllegraŽ (Fexofenadine Hydrochloride) is indicated for the relief of symptoms associated with seasonal allergic rhinitis and for the treatment of uncomplicated skin manifestations of chronic idiopathic urticaria in adults and children 6 years of age and older.

Barr Pharmaceuticals, Inc. is a holding company whose principal subsidiaries, Barr Laboratories, Inc. and Duramed Pharmaceuticals, Inc., develop, manufacture and market generic and proprietary pharmaceuticals.
