Filitra 20 mg is a prescription medication 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 arousal, helping men achieve and maintain a firm erection. Vardenafil works by inhibiting the PDE5 enzyme, which is responsible for breaking down cyclic GMP (cGMP) in the penis. cGMP is responsible for relaxing the smooth muscles of blood vessels, allowing for increased blood flow during sexual arousal. By blocking PDE5, Filitra 20 mg helps sustain cGMP levels, leading to improved erectile function. https://www.genericday.com/filitra-20-mg.html
