Generic Viagra will not until 2019

Right now that Spain is raising some controversy because the government wants to force the sale of generic drugs to help save, a trial was held between Pfizer, the maker of Viagra, and Teva, the largest manufacturer of generic products.

The case was that next year one of the patents expired Viagra, so that Teva could use the same active ingredient (sildenafil citrate) to develop a "generic viagra", this obviously does not like Pfizer, and who have invested heavily in developing it, and year after year earns them a lot of money, not for nothing is one of the company's flagship products.

To try to extend its exclusivity on the goose that lays the golden eggs, Pfizer has another patent claimed that referred specifically to the use of this active as a treatment for erectile dysfunction.

Pfizer eventually won the appeal it had filed in federal court in Norfolk, United States, for violation of his patent by the Israeli company Teva Pharmaceuticals Industries, which now can not launch its generic drug until the October 2019 .

Although this gives a respite to Pfizer, really this decision still be appealed, and the best we are talking about 8 years lost in the patent of Viagra, a product that last year I reported two billion dollars .

What's more, this must be added the impending loss of patent for Lipitor, the world's best selling drug last year alone that brought them ten billion dollars, bringing the company's future is a little disturbing.
