Mechanism of action of Tadacip 20mg

Tadalafil is a selective inhibitor of phosphodiesterase-5, which increases cyclic GMP thus, enhancing the erectile function. Penile erection is caused by increased penile blood flow resulting from the relaxation of penis arteries and smooth muscles. This action is mediated by the discharge of nitric oxide from endothelial cells and nerve terminals, which stimulates the synthesis of c-GMP in the smooth muscle cells. Cyclic GMP causes relaxation of smooth muscle resulting in increased blood flow into the smooth muscles of penis. The inhibition of phosphodiesterase-5 therefore, enhances erectile function by increasing the amount of c-GMP.
