Vilitra is a medication used to treat erectile dysfunction (ED) in men. It contains vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor that enhances blood flow to the penis during sexual arousal, facilitating an erection. Vardenafil in Vilitra 20 mg blocks the PDE5 enzyme, leading to increased levels of cyclic guanosine monophosphate (cGMP). This relaxation of smooth muscle and dilation of blood vessels allows for improved blood flow to the penis, facilitating an erection in response to sexual arousal.
