Filitra 20 mg is a medication used to treat erectile dysfunction (ED) in men. It contains vardenafil, the same active ingredient found in Levitra, which works by increasing blood flow to the penis, helping men achieve and maintain an erection when sexually aroused. cGMP helps relax the blood vessels in the penis, enabling blood to flow more freely. By inhibiting PDE5, vardenafil increases blood flow, helping men achieve and sustain an erection when sexually stimulated.
