Vilitra 20 mg is a medication used to treat erectile dysfunction (ED) in men. It contains vardenafil, a potent phosphodiesterase type 5 (PDE5) inhibitor that improves blood flow to the penis, helping achieve and maintain an erection during sexual stimulation. Vardenafil increases the levels of cyclic guanosine monophosphate (cGMP) by inhibiting the PDE5 enzyme. This results in relaxation of smooth muscles and dilation of blood vessels in the penis, enhancing blood flow necessary for a firm erection.
