The active ingredient in
LEVITRA works specifically on the chain of events
that occur in the penis during arousal.
LEVITRA belongs to a class
of drugs called "PDE-5 inhibitors." It works by
increasing blood flow to the penis to improve
erectile function.
In
clinical trials, LEVITRA was shown to help men get
and keep an erection for successful intercourse.
LEVITRA won't cause an
embarrassing, instant erection. For most men,
LEVITRA did not cause an erection for longer than
they were sexually stimulated.
