What is Viagra?

Uses

Sildenafil is used to treat male sexual function problems (impotence or erectile dysfunction-ED). In combination with sexual stimulation, sildenafil works by increasing blood flow to the penis to help a man get and keep an erection.This drug does not protect against sexually transmitted diseases (such as HIV, hepatitis B, gonorrhea, syphilis).

Fast facts on Viagra

Effects

Viagra can help men who cannot achieve or sustain an erection due to erectile dysfunction. It improves the erectile response when a man is already sexually stimulated, but it does not provide sexual stimulation. If there is no sexual stimulation, viagra will not work.When sexual stimulation occurs, nitric oxide is released by the nervous system in the erectile tissue of the penis. Nitric oxide stimulates an enzyme that produces messenger cyclic guanosine monophosphate (cGMP).cGMP causes the arteries in the penis to dilate, so that the arteries and the erectile tissue fill with blood. An erection results.
