About Viagra

The National Institutes of Health estimated that 5 percent of 40-year-old men will suffer from Erectile Dysfunction or ED on a long term basis. The rate is higher for men aging about viagra65-year-old and above which is estimated at 15 to 25 percent. This would mean that there are at least 15 million to 30 million men who are suffering from this condition.

However, men should not worry because there are different approaches which can be used to treat this condition.

What is Viagra?

Viagra (sildenafil citrate) is an oral drug used to treat impotence or erectile dysfunction. It becomes the most prescribed drug for ED after the FDA approved it in 1998. In fact, Viagra was able to capture more than 90% market share in 2000. This is a proof that the drug really works well as treatment for men with ED problem. However, the introduction of other similar drugs like Levitra and Cialis led to the decline of its sales worldwide. Research shows that the success rate of the drug when used as a treatment for erectile dysfunction is more than 70%. This drug, which is produced by Pfizer, is also called as "the blue pill" and "vitamin V."

How Viagra Works?

Before the introduction of Viagra in the market, medical treatments available for ED were surgical implants, pumps, suppositories, and drugs injected into the penis. Viagra offered a better way to solve this problem in men. It works by selectively dilating blood vessels in the penis, improving blood flow and allowing a natural sexual response. The drug delay the enzymes called phosphodiesterase type 5 from working too quickly and regulate the blood flow in the penis. Maintained erection is achieved when the penis is physically stimulated.

Viagra works well for men who are experiencing inconsistent ability to achieve an erection, suffering from total inability to achieve erection, or can only sustain a brief erection.
