Erectile Dysfunction is the inability to get or sustain the desired penile erection. It belongs to the class of Phosphodiesterase inhibitors.
Mechanism of action of Levitra:
The mechanism of action of this drug is like that of Viagra and Tadalafil. The erection of the penis depends on the flow of blood into the penile tissues. An increased flow of blood in the blood vessels of the penis causes the engorgement of the penis due to increases in the size of blood vessels. At the same time, the size of the blood vessels carrying blood away from the penis also decreases which results in less removal of blood from these arteries helpful in maintaining the erection.
The first step involved in the engorgement of blood vessels in the sexual stimulus that causes erection due to the release of nitric oxide in the penis. Due to a release of nitric oxide guanylate cyclase is produced which leads to the production of cyclic guanosine monophosphate (cGMP). The increasing and decreasing size of blood vessels which controls the flow of blood in the penis is dependent on this enzyme. Levitra prevents phosphodiesterase-5 (PDE-5) enzyme from destructing the cGMP enzyme to sustain its level in the body for a longer duration of time. The longer persistence of cGMP prolongs the engorgement of the penis for a longer period.
