Vidalista 80 is a clinically proven PDE5 inhibitor that helps treat erectile dysfunction in men. This drug increases the body’s levels of cGMP, an enzyme that produces an erection. This enlarged vein leads to a more distinct mass of blood in the penis, resulting in erection and arousal during pre-regulated sex. A PDE5 inhibitor like Vidalista 80 mg works by preventing PDE5 enzyme activity and improving blood flow to the penis. Unlike Viagra, however, Vidalista black 80 mg does not cure erectile dysfunction and should be used in conjunction with sexual incitement.
