    In clinical studies, VIAGRA was assessed for its effect on the ability of men with erectile dysfunction (ED) to engage in sexual activity and in many cases specifically on the ability to achieve and maintain an erection sufficient for satisfactory sexual activity. VIAGRA was evaluated primarily at doses of 25 mg, 50 mg and 100 mg in 21 randomized, double-blind, placebo-controlled trials of up to 6 months in duration, using a variety of study designs (fixed dose, titration, parallel, crossover). VIAGRA was administered to more than 3,000 patients aged 19 to 87 years, with ED of various etiologies (organic, psychogenic, mixed) with a mean duration of 5 years. VIAGRA demonstrated statistically significant improvement compared to placebo in all 21 studies. The studies that established benefit demonstrated improvements in success rates for sexual intercourse compared with placebo. The effectiveness of VIAGRA was evaluated in most studies using several assessment instruments. The primary measure in the principal studies was a sexual function questionnaire (the International Index of Erectile Function - IIEF) administered during a 4-week treatment-free run-in period, at baseline, at follow-up visits, and at the end of double-blind, placebo-controlled, at-home treatment. clomid for low testosterone The little blue pill may not have ever been if not for one dutiful nurse.

The US military shells out $41.6 million per year for it, and from 2012 onward, the US, Mexico, and Canada spent about $1.4 billion on it annually (although those numbers are projected to fall in the coming years when Pfizer’s patent on the drug expires in 2020).

It is also used in the treatment of high blood pressure specific to the heart and the arteries that feed the lungs. The generic name of the drug is sildenafil (pronounced sill-den-a-fill).

The "little blue pill" could one day have a surprising use: as a cancer prevention drug. Early research in mice suggests that small doses of sildenafil, the ingredient in Viagra responsible for the pill's effects, may prevent colorectal cancer. When the researchers gave the drug to mice that were prone to developing colorectal cancer, the drug was linked to a 50 percent reduction in the number of precancerous polyps that formed in the animals' intestines, compared with mice that weren't given the drug.
