Vilitra 20 mg is a prescription medicine used to treat erectile dysfunction (ED) in men. It contains vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor that improves blood flow to the penis during sexual stimulation, helping achieve and maintain a firm erection. When a man is sexually aroused, nitric oxide is released in the body, which increases a chemical called cGMP. This relaxes blood vessels in the penis and improves blood flow. Vardenafil helps prevent the breakdown of cGMP, allowing erections to be stronger and last longer when sexual stimulation occurs.
