Generic player Teva has won 180 days exclusivity for Losartan (Cozaar) and Losartan + HCTZ (Hyzaar) after Court of Appeals for District of Columbia Circuit overturned a lower court's decision that Teva had forfeited its exclusivity rights in the light of delisting of another Orange Book patent on polymorph by innovator Merck & patent assignee Du Pont.
The product patent on Losartan (Cozaar) and Losartan + HCTZ (Hyzaar) will expire on Apr 06, 2010. Now, other generic players will be able to launch this product after the expiry of Teva's 180 days exclusivity in Oct, 2010.
