Generic Viagra is an oral prescription medicine which treats a condition called Erectile Dysfunction(ED) in men. ED is a sexual disorder under which the penis gets neither stiff nor expands when men are sexually aroused and thus are unable to attain and maintain erections.

Generic Viagra comes under the class of medicines called Phosphodiesterase inhibitors. Vardenafil is the active ingredient present in Generic Viagra. It calms the muscles present in the erectile organ and increase the flow of blood which results in a better erection required for satisfactory sexual activity. The point to be noted is that Generic Viagra doesn’t protect against health conditions like HIV infection and pregnancy.
