    Viagra (sildenafil) is one of the most widely-known prescription drug names on the U. ED is a common sexual problem for men and its frequency increases with age. Pfizer realized ED was an unmet medical need and a major opportunity for financial gain. Often dubbed "the little blue pill", Viagra (sildenafil) was the first phosphodiesterase 5 (PDE5) inhibitor approved to treat erectile dysfunction (ED). During the heart clinical trials, researchers discovered that the drug was more effective at inducing erections than treating angina. The sildenafil compound was originally developed by Pfizer for the treatment of hypertension (high blood pressure) and angina pectoris (chest pain due to heart disease). The discovery that sildenafil could lead to an erection was an unplanned event. survey determined about 50 percent of men 40 to 70 years of age experience some degree of ED. In 1998, the FDA approved Viagra, the first oral treatment for erectile dysfunction, under a priority review. At the time of its approval, Viagra had the fastest initial sales growth following its launch of any prescription product, reaching 2008 sales of close to $2 billion. where can i buy retin a in south africa Sildenafil is a vasoactive agent used to treat erectile dysfunction and reduce symptoms in patients with pulmonary arterial hypertension (PAH). Sildenafil elevates levels of the second messenger, c GMP, by inhibiting its breakdown via phosphodiesterase type 5 (PDE5). PDE5 is found in particularly high concentrations in the corpus cavernosum, erectile tissue of the penis. It is also found in the retina and vascular endothelium. Increased c GMP results in vasodilation which facilitates generation and maintenance of an erection. The vasodilatory effects of sildenafil also help reduce symptoms of PAH.

    SXSW is still going on in Austin at the moment but the EDU and Interactive conferences are officially done. That is over 30% of the normal population of Austin. Over 250k people will come to Austin for SXSW this year. Multiple venues, 20-30 sessions per hour and thousands of parties. I thought it might be good to summarize what SXSW Interactive really talked about. It is hard to digest but if you pick off the things that interest you the most, you can really get a lot out of it. Keys to having any of these predictions/statements come true will be dependent on the 2012 Presidential election.
