The perfect medicine for Sexual dysfunction treatment

What most people don't know about Viagra is the fact that it was discovered by accident.

At the beginning of the 1990s Pfizer, one of the world leading pharmaceutical companies was testing a drug for the treatment of a heart disease called angina pectoris. The medicine failed to reduce arterial blood pressure but triggered an interesting side effect with most male patients: erection. Researchers realized then they discovered something of great importance and after further studying they turned the side effect of the first drug into a prime effect thus creating Viagra.

In 1996 Viagra was patented with the intent of developing a treatment for erectile dysfunction. At the end of the 1998 it received approval from The Food and Drug Administration being quickly accepted and used world wide.

Viagra acts based on the existence of nitric oxide (NO) an important signaling molecule present in human body. Its existence was discovered in 1987 by Louise Ignarro an American pharmacologist at California University and his assistant Georgeta Buga a research biologist. They managed to prove that once released in the blood vessel NO can trigger the relaxation of downstream vessels. Therefore it can also act as a vasodilator in the penile erection.

The World Health Organization recommends Viagra as first aid when it comes to erectile dysfunctions and admits its efficiency. Sidenafil (the common name of the active substance in Viagra, one by which the medicine gets classified in pharmacies) has proven its effectiveness regardless the etiology of the erectile dysfunctions.

The world is making progress very fast. Scientists of modern age are trying to make those things which may help them in the future. But on the other side these things are creating problem for us. You are well familiar about the usage of car that helps to move us from one place to another but it also creates environment pollution. If there is any positive aspect of a thing then there is also a negative aspect of the same thing. Same is the case with people. In the past, they less use the technology and did their work with their own hands. But now they use machines for their work that is why they are becoming the victim of different diseases.
