Vilitra 40 mg is a high-dose prescription medicine used to treat erectile dysfunction (ED) in adult men. It contains vardenafil, which belongs to the phosphodiesterase type 5 (PDE5) inhibitor class. These medicines help improve blood flow to the penis during sexual stimulation. Vilitra 40 mg blocks the PDE5 enzyme, which normally breaks down cyclic guanosine monophosphate (cGMP). When PDE5 is inhibited, cGMP levels rise, leading to relaxation of smooth muscles in penile blood vessels. This improves blood circulation and helps achieve and maintain an erection during sexual arousal.
