Generic Viagra slated for release in 2017 – timesherald

WASHINGTON – Generic Viagra will hit the market more than two years ahead of schedule under an agreement between Teva Pharmaceutical Industries and the manufacturer of the impotence drug, Pfizer.

Teva will be able to enter the market on December 11, 2017 and will pay patent royalties until the Viagra patent expires in April 2020, New York-based Pfizer said in a statement. Other terms were not disclosed.

Viagra, the chemical name of which is sildenafil citrate, is one of Pfizer’s best-known drugs. The drug sold for $ 2.05 billion in 2012, its best year ever. Earlier this year, Pfizer began selling the blue pill through a company-sponsored website to combat counterfeit versions sold online.

The drug came from a group of compounds considered during research to treat high blood pressure and angina pectoris. Help with erectile dysfunction was a side effect discovered in testing, and the patent, issued in 2002, relates to the use of the compound to treat impotence.

Some aspects of the patent had already been rejected in 2010 because it was similar to a Chinese herb known as Horny Goat Weed. Teva lost its offer to invalidate the remainder of the patent at trial and appealed the case. The United States Court of Appeals for the Federal Circuit today dismissed the appeals.
