A bit of history

Since 1977, the American pharmacologists were working to create a substance that can constrict and dilate blood vessels in heart, brain, and lungs. However, until 1992 scientists began testing sildenafil citrate, meaningful results were not achieved. Tests were conducted in order to create a medication for cardiovascular system diseases treatment.

Sildenafil citrate has shown unexpected ability to block certain enzymes that lead to blood vessels expansion in the pelvic area. This substance causes a persistent and prolonged erection that pleasantly surprised men involved in clinical trials. Thereafter, sildenafil citrate was examined in an absolutely different direction. As a result, in 1998, famous Viagra pill came to light. In the same year, three scientists were awarded the Nobel Prize for the creation of drug for heart and lungs diseases treatment.
