Sildenafil citrate, sold as Viagra, Revatio and under various other trade names, is a drug used to treat erectile dysfunction and pulmonary arterial hypertension (PAH). It was developed and is being marketed by the pharmaceutical company Pfizer. It acts by inhibiting cGMP specific phosphodiesterase type 5, an enzyme that regulates blood flow in the penis. Since becoming available in 1998, sildenafil has been the prime treatment for erectile dysfunction; its primary competitors on the market are tadalafil (Cialis) and vardenafil (Levitra).
Viagra pills are blue and diamond-shaped with the words "Pfizer" engraved on one side, and "VGR xx" (where xx stands for "25", "50" or "100", the dose of that pill in milligrams) engraved on the other. The dose of sildenafil for erectile dysfunction is 25 mg to 100 mg taken not more than once per day between 30 minutes and 4 hours prior to sexual intercourse.
The dosage for pulmonary arterial hypertension (Revatio) is one 20 mg tablet three times a day. Revatio pills are white, round, film-coated tablets imprinted with "RVT 20" embossed on one side.
Viagra is one of the best-known drugs of all time:
* Billions of spam e-mail messages advertise Viagra every day. There is so much Viagra spam, in fact, that Pfizer (the maker of Viagra) has a page addressing the problem, called Avoid Fake Viagra.
* Pfizer has spent untold millions of dollars advertising Viagra, so you see advertisements for the drug constantly on TV.
* Pfizer claims on its Web site that nine Viagra pills are dispensed every second -- nearly 300 million tablets per year.
The name recognition of Viagra is so good that nearly every adult in America has heard of the drug and can tell you what it does.
What Viagra does is simple: When it works as intended, Viagra causes a man who is sexually stimulated to get an erection.

February 9 to 11, 2006
Universidad de Los Andes, Bogota
This meeting will bring together economists, behavioral scientists, ecologists, mathematicians and modelers, to address still open questions on the “tragedy of the commons” problem. The origins of the problem of cooperation involve the understanding of the interactions and co-dependence between the formal and informal rules of the game, and the individuals’ preferences with respect to time, perception of risk, the environment and other human beings. The group of scientists invited will bring a series of novel approaches to these questions, and applied to various domains that touch the problem of collective action and cooperation.
