Viagra Drug Information:

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. Another brand of Sildenafil is Revatio, which is used to treat pulmonary arterial hypertension and improve exercise capacity in men and women.
