Viagra

What Is Viagra

Impotency, what earlier had been called ‘curse from the heaven’, is not a problem these days - all thanks to Viagra. Yes, the diamond-shaped blue pill completely changed the people’s perception towards sexuality, just after its invention. If you still don’t know what Viagra is, then here comes the answer. With ‘sildenafil’ as the generic name, Viagra is a drug that is used to treat men who have problem in getting an erection, a state better known as impotence or erectile dysfunction (ED).

Invention of Viagra

In 1991, Viagra was developed during an experiment that was proposed to find out medications to cure cardio-vascular ailments. During the clinical trials by Pfizer, at Sandwich, it was discovered that the drug had minute effect on angina, but could improve and sustain men’s penile erection. Then and there, Pfizer stopped the research on Sildenafil as medication for heart and instigated analysis on it for penile erection.

Inventor of Viagra

Pfizer tried to keep secret the name of the original inventors, but could not. Peter Dunn and Albert Wood were held responsible for the invention of miraculous drug. Many other scientists and doctors claimed to have invented the drug, but on the whole, Pfizar got the patents in its name after much speculation. Approved for erectile dysfunction by the U.S. Food and Drug Administration, Viagra is not meant to delay ejaculation or prolong erections.

How Does Viagra Work?

Viagra, after it got revealed to the world in 1998, has done wonders to enhance the sexual lives of many grief-stricken souls. It enables the blood vessels in the penis to lighten up and facilitates blood flow through them, consequently improving a man’s reaction to sexual stimulation. One more thing to understand is that Viagra doesn’t cause erection merely by taking a pill. Sexual stimulation is necessary to get the effective results of Viagra.
