Vidalista 10 mg 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 10 mg works by preventing PDE5 enzyme activity and improving blood flow to the penis.
