What is Generic Viagra?
Generic Viagra is made by a different company, not the original license owner. Nonetheless it is exactly the same as brand Viagra, though it may have different shape, color or name. Generic Vigra is usually much cheaper than the brand analogue.
Viagra is a patented medicine with a registered trademark. Because it is a brand name, no one other than the Pfizer company is allowed to market a product called Viagra. The term generic viagra is used to refer to products that are chemically identical to Viagra, but sold under another name (usually sildenafil citrate).
Sildenafil citrate is the chemical name of the little blue pill known as Viagra. In the 1990’s the Pfizer company was doing research with a chemical that was being tested to treat angina.
During clinical trials it was noticed that the drug did not help angina sufferers, but some of the men who were taking part in the tests reported they got an erection when their penis was stimulated by touch.
Even more important was the fact that men who had previously been diagnosed as impotent were getting the same results as men who had no history of erectile dysfunction. Impotence, also called erectile dysfunction, is not being able to achieve and maintain an erection to orgasm.
Pfizer decided to test sildenafil citrate for treating impotence with some very impressive results. Viagra was then patented in 1996, and in 1998 it was approved by the F.D.A. as a pill to treat erectile dysfunction. 50 milligrams is the recommended standard viagra dose size but some users require 100 milligram doses.
