NEW YORK A U.S. District Court has granted French drug maker Sanofi-Aventis and Albany Molecular Research an injunction halting the launch of a generic version of one of its drugs made by Dr. Reddy’s Labs, Dr. Reddy’s said.
The U.S. District Court for the District of New Jersey blocked the release of Dr. Reddy’s fexofenadine hydrochloride and pseudoephedrine hydrochloride extended-release tablets in the 180 mg and 240-mg strength, a generic version of Allegra D24, marketed by Sanofi-Aventis and discovered by Albany Molecular Research.
Dr. Reddy’s said it strongly disagreed with the lawsuit and intended to appeal. According to published reports, the Food and Drug Administration had approved Dr. Reddy’s version of the drug following a 30-month stay of approval resulting from a patent infringement lawsuit filed against the company when it tried to seek approval for the generic. The last patents covering Allegra D24 expire in December 2020.
