Tadalafil is the active salt in Buy Vidalista 20 mg, which functions as a PDE-5 inhibitor. The function of the PDE5 enzyme is impeded, leading to an elevation in the levels of cGMP or cyclic Guanosine Monophosphate. Increased levels of cGMP cause the blood vessels in the penis to widen and the muscles to relax, resulting in an enhanced flow of blood to the area. This facilitates an individual in attaining and maintaining an erection.
