Sildenafil had its 10th glorious Birthday on March 27, 2008.
Sildenafil citrate, on March 27, 1998, was approved by the Food and Drug AdministrationFDA for use in erectile dysfunction in the United States. In the history of Sexual Medicine Sildenafil is the
scientifically proved effective and therefore approved for the treatment of Erectile Dysfunction ED. Today other medicines somewhat similar and perhaps better than Sildenafil are in use by men world over. Ironically, no such drug is yet born for women.

Having said this I must mention that sildenafil is remarkably safe medicine, one that has been in market for ten years and consumed by over 40 billion people*** in the world just in one night.
After the U.S. Food and Drug Administration granted approval for Viagra on 27 March 1998, doctors prescribed the drug more than any other medicine in history over a two-year time span. Pfizer Inc., the maker of Viagra, uses celebrities such as former senator Bob Dole and baseball star Rafael Palmeiro to advertise directly to consumers, contributing to the $15.7 billion total spent in 2000 on pharmaceutical ads targeted toward ordinary people—instead of doctors.****
Sildenafil (compound UK-92,480) was synthesized by a group of pharmaceutical chemists working at Pfizer’s Sandwich, Kent research facility in England. It was initially studied for use in hypertension (high blood pressure) and angina pectoris (a form of ischaemic cardiovascular disease). Phase I clinical trials under the direction of Ian Osterloh suggested that the drug had little effect on angina, but that it could induce marked penile erections. Pfizer therefore decided to market it for erectile dysfunction, rather than for angina. The drug was patented in 1996, approved for use in erectile dysfunction by the Food and Drug Administration on March 27, 1998, becoming the first pill approved to treat erectile dysfunction in the United States. Annual sales of Viagra© in the period 1999–2001 exceeded $1 billion.*****
Actual figure of global consumption per day of sildenafil needs verification.
