Vilitra 40 mg is a prescription medication used to treat erectile dysfunction (ED) in men. It contains vardenafil, a PDE-5 (phosphodiesterase type 5) inhibitor that helps increase blood flow to the penis, enabling men to achieve and maintain an erection during sexual stimulation. During sexual arousal, the body releases nitric oxide, which stimulates cyclic GMP (cGMP) production in penile tissue. cGMP relaxes smooth muscles in blood vessels, increasing blood flow into the erectile tissue. Vardenafil in Vilitra 40 mg blocks the PDE-5 enzyme that breaks down cGMP, helping sustain an erection.
