Is Viagra FDA Approved?

The Food and Drug Administration, U.S.A. approved the impotence pill Viagra on 27th March, 1998 . Viagra is the first oral pill to treat impotence or ED(erectile dysfunction) in men. Unlike previously approved treatments for impotence, Viagra does not directly cause penile erections, but affects the response to sexual stimulation.

The drug acts by enhancing the smooth muscle relaxant effects of nitric oxide, a chemical that is normally released in response to sexual stimulation. This smooth muscle relaxation allows increased blood flow into certain areas of the penis leading to an erection. Viagra was tested in more than 3000 men with erectile dysfunction due to various reasons, such as spinal injury, diabetes, cardiovascular diseases, history of prostate surgery and also such men who did not have any particular organic reason for erectile dysfunction. Patients reported that they most often than not were successful to get their erection and also maintain it. The recommended dose is 50mg according to FDA which individuals should use 1 hour before their sexual activity but individuals may need more than that, that is, 100 mg ,or less, that is, 25mg.

Viagra has become the most popular anti-impotency drug since its launch. Every second around 9 pills are sold and approximately 16 million men in the entire world have opted to be treated by viagra for their problems of ED (Erectile Dysfunction).

However Viagra does not claim to offer any resistance against the STD (sexually transmitted disease).
