Tadalafil is essentially a vasodilator in Vidalista black. It is primarily a type 5 inhibitor of phosphodiesterase. The inhibition of type 5 phosphodiesterase contributes to an increase in the concentration of cGMP. Cyclic guanosine monophosphate induces relaxation of the blood vessels. This leads to erection due to further blood flowing in the area.
