Filitra is a medication used for the treatment of erectile dysfunction (ED) in men. It contains vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor that helps improve blood flow to the penis during sexual stimulation. Vardenafil works by blocking the PDE5 enzyme, which normally breaks down cyclic guanosine monophosphate (cGMP). By helping maintain cGMP levels, Filitra allows the smooth muscles in penile blood vessels to relax, increasing blood flow and making it easier to achieve and maintain an erection.
