  How does Viagra work? – Buy Viagra tablets UK

  The active ingredient in Viagra is sildenafil, which is known medically as a PDE5 inhibitor. Sildenafil inhibits (blocks) an enzyme which regulates blood flow in the penis. PDE5 inhibitors multiply the natural process of arousal and increase blood flow to the penis in situations of sexual stimulation. Sildenafil helps to achieve an erection but relies on natural arousal as a trigger. It, and other PDE55 inhibitors such as tadalafil, vardenafil, and avanafil, support sexual relations when erections are failing.

Viagra (sildenafil) relaxes muscles found in the walls of blood vessels and increases blood flow to particular areas of the body.

Viagra is used to treat erectile dysfunction (impotence) in men. This page contains specific information for Viagra, not Revatio.

Do not take Viagra while also taking Revatio, unless your doctor tells you to.
