How Levitra Works
This drug belongs to the group of PDE-5 inhibitors, the active component of which is vardenafil. It enhances erectile function by providing smooth muscle relaxation due to the increase of cyclic guanosine monophosphate amount. The condition of smooth muscles relaxation leads to improvement of the blood flow in the penis and, consequently, results in a sufficient erection.
Levitra is a selective PDE-5 inhibitor, which means it works only when there is sexual stimulation. When you swallow a pill of Levitra, it is absorbed in your stomach and comes to the target location with proteins in the blood, but an erection takes place just as soon as you experience sexual excitement.

Doctors may prescribe it to male patients since the age of 18 if some erectile disorders connected with an inability to prolong a sexual intercourse, absence of necessary erection to perform the intercourse, etc. are experienced.
