What is the mechanism of action of Levitra?
Levitra is a new class of medication to help men with erectile dysfunction (impotence). Viagra was the first of the so called, "PDE-5 inhibitors" and Levitra is known in the same class to significantly help individuals treat their erectile dysfunction (impotence). Similar to Viagra, Levitra increases the quantity of blood supplied to the penis thus improving the erection. Levitra is very selective in inhibiting the PDE-5 without affecting other isoenzymes. This allows a smaller dose of Levitra to have a more pronounced effect as a larger dose of Viagra (the standard dose of Levitra dose is 10mg while the standard dose of Viagra dose is 50mg). Through this action, smooth muscle in the penis remains relaxed for a longer period. This allows for increased blood flow into the cavernous tissue of the penis thereby generating an erection. Levitra is unique in that it increases a natural occurring process, therefore, only through sexual stimulation will an erection occur.
More specifically, Penile erection is a haemodynamic process. During sexual stimulation, nitric oxide is subsequently released. The nitric acid activates an enzyme guanylate cyclase, resulting in an increased level of cyclic guanosine monophosphate (cGMP) in the corpus cavernosum of the penis. This results in smooth muscle relaxation in the penis, allowing increased inflow of blood into the penis. The level of cGMP is regulated by the rate of synthesis via guanylate cyclase and by the rate of degradation via cGMP hydrolysing phosphodiesterases (PDEs).
Levitra is a potent and selective inhibitor of the cGMP specific phosphodiesterase type 5 (PDE5), the most prominent PDE in the human corpus cavernosum. Levitra enhances the effect of endogenous nitric oxide in the corpus cavernosum by inhibiting PDE5. When nitric oxide is released secondary to sexual stimulation, inhibition of PDE5 by Levitra results in increased corpus cavernosum levels of cGMP. Sexual stimulation is required for Levitra to produce its beneficial therapeutic effects.

Individuals can take Levitra with or without food, however, preferably not following a heavy or a meal high in fat content. In addition, individuals should not take Levitra with grapefruit juice, remember excessive alcohol can result in erectile dysfunction (impotence).
