Barr receives U.S. approval for generic Razadyne tabletsBarr Pharmaceuticals, Inc. today announced that its subsidiary, Barr Laboratories, Inc., received final approval from the U.S. Food Drug Administration (FDA) to manufacture and market a generic version of Ortho McNeil Janssen's Razadyne (galantamine hydrobromide), 4 mg, 8 mg and 12 mg tablets. Barr intends to launch its generic Razadyne tablets product immediately. Barr filed an Abbreviated New Drug Application (ANDA) with the U.S. Food Drug Administration (FDA) for Janssen's Razadyne (galantamine hydrobromide), 4 mg, 8 mg and 12 mg tablets on February 28, 2005, the first day that an ANDA containing a Paragraph IV certification could be submitted based on the expiration of the New Chemical Entity (NCE) exclusivity on the product. Following receipt of notification from the FDA of the application's acceptance for filing, Barr notified the New Drug Application (NDA) holder and patent owner of Barr's challenge to the patents protecting Razadyne. On June 15, 2005, Barr announced that Janssen had filed suit in the District Court for the District of Delaware, and the trial occurred in May 2007.
