Levitra is an inhibitor of phosphodiesterase of 5th type (PDE5) and is used for the treatment of male erectile dysfunction, as was mentioned earlier. During the erection hemodynamic process occurs that relaxes the smooth muscle of cavernous bodies of a penis and arterioles in it. During sexual stimulation first wave of nitric oxide (NO) emission occurs from the cavernous bodies and cyclic guanosine monophosphate (cGMP) is increased. This is accompanied by muscle relaxation of cavernous bodies, and as result blood flow to the penis is increased. The function of Levitra (vardenafil) is blocking of PDE5, which split cGMP, during sexual stimulation endogenous NO in the cavernous bodies is increased and the drug increases the reaction to sexual stimulation.
