Levitra (Vardenafil)

Like sildenafil, Levitra and tadalafil are selective inhibitors of the phosphodiesterase (PDE) isoenzyme PDE-5, which is predominantly responsible for degrading cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the corpus cavernosum. During sexual stimulation, nitric oxide is released from cavernous nerves and endothelial cells and activates the enzyme guanylate cyclase, resulting in increased cGMP synthesis. The cGMP triggers relaxation of smooth muscles, allowing increased blood flow into the penis and expansion of sinusoidal spaces; this prevents venous blood outflow and results in erection. The PDE-5 inhibitors can potentiate erections by enhancing and prolonging the smooth musclerelaxant effects of the nitric oxide-cGMP cascade in the corpus cavernosum. PDE-5 inhibitors have no effect without sexual stimulation.
