About Viagra

Viagra is an effective drug for the treatment of erectile dysfunction. It increases blood flow to the penis. It works by:

• Increasing the amount of nitric oxide produced in the penis

• Increasing the amount of cGMP produced in the penis in response to the nitric oxide

• Eliminating the PDE5 in the penis so that the cGMP builds up instead of getting decomposed by the PDE5

Viagra eliminates the PDE that decomposes the cGMP, so that the cGMP builds up in the penis and has a greater effect on the artery walls. The enhanced the amount of cGMP is the greater is the blood flow; the greater is the blood flow the greater is the degree of erection.

The reason that Viagra uses this technique is because of an interesting peculiarity of PDE.

It turns out that the human body produces at least 11 different kinds of PDE. Only one of those kinds of PDE - the PDE5 - is found primarily in the penis. Once this fact was discovered, the creation of Viagra was relatively simple. Pfizer found a chemical that would selectively block PDE5 and nothing else. With the PDE5 blocked, cGMP could build up in the penis and increase the blood flow there without affecting other parts of the body.

PDE5 is an enzyme that is a specially folded protein that can speed up a chemical reaction. Sildenafil, the active ingredient in Viagra accepts the cGMP and breaks it down. It fits right into the PDE5 enzyme and disables it.

When a man takes a Viagra pill, the Sildenafil citrate flows throughout his body, only affecting the PDE5 enzyme in the penis. It stays in the bloodstream for about four hours, and is then washed out of the blood by the liver and the kidneys.

Viagra is both well-tolerated and effective even when used in conjunction with high blood pressure medications. However like other prescription medications, it also has its share of the side effects, most of which are mild to moderate and short-lived. The most common side effects include headache, facial flushing, indigestion, dizziness, nasal congestion and abnormal vision.
