Viagra

Viagraâ„¢ was approved by the FDA in March 1998 for the treatment of male impotency. Viagra is the first oral pill to treat impotence, a dysfunction that affects millions of men in the United States and the world. Viagra is manufactured by Pfizer Pharmaceuticals, New York, NY.

When a man suffers from erectile dysfunction, there can be many reasons for the problem. But one of the most common reasons, especially in older men, is that the arteries in the penis arent dilating enough when the brain sends the signal. The man is aroused, and the nerves in the penis are producing NO; but the amount of cGMP produced is not enough to maintain an erection.

The way that Viagra® goes about solving this problem is quite ingenious and successfull.

Viagra increases the body ability to achieve and maintain an erection during sexual stimulation. Viagra will not produce a spontaneous erection, but aids the body natural erection process.

Reports released in October 1997, indicate Viagra achieved a success rate of 80% for the treatment of sexual erectile dysfunction.
