Viagra™ Information

In 1998, The Food and Drug Administration announced the approval of Viagra™, the first oral pill to treat erectile dysfunction in men. Viagra™ is Pfizer's brand name for sildenafil citrate, which is chemically a selective inhibitor of cyclic guanosine monophosphate - specific PDE5.

Viagra™ is sold at dosages of 25, 50, and 100 milligram and it should be taken only once per 24-hour period. For best results, Viagra™ should be swallowed on an empty stomach (for better absorption and lesser burps). It works best when taken at a dosage of 100mg, but a 100-miligram dose may be too generous for men who are younger and healthier.

Approximately 30-60 minutes later, the drug is absorbed in the bloodstream and ready to take action. Unlike previously approved treatments for impotence (like Yohimbine), Viagra™ does not directly cause erections, but affects the response to sexual stimulation. The man still needs to be in a situation that produces arousal. Read about how Viagra™ works for details.

Viagra™ Studies and Reports

In clinical trials, Viagra™ was assessed for its effect on the ability of men with erectile dysfunction to achieve and maintain an erection. Viagra™ was administered to more than 3,000 patients aged 19-89 years, with impotence of various etiologies (organic, psychogenic, mixed). Viagra™ demonstrated statistically significant improvement compared to placebo in some 21 different studies including the following:

Some 78% of men reported improved erections while taking 50 mg and 100 mg doses of Viagra™ (verses only 24% on a placebo).

In patients with psychogenic etiologies 84% of individuals taking Viagra™ reported improved erections (verses 26% on a placebo).

Across all trials, Viagra™ improved the erections of 43% of radical prostectomy patients (verses only 12% on a placebo). Recent studies reveal that orgasms are enhanced by Viagra™ as well as intercourse satisfaction, and overall satisfaction independent of erection.

While Viagra™ is often effective and fast acting - it typically boosts blood flow within 30 minutes to several hours - some people prefer non-drug alternatives. Several interesting herbal supplements have recently come to light and may provide benefits. Read about how Viagra™ alternatives work for details.
