Filitra 20 is a tablet that contains 20 mg of Vardenafil, a prescription medicine used to treat erectile dysfunction (ED) in adult men. Vardenafil works by blocking the enzyme Phosphodiesterase type 5, which normally restricts blood flow in the penis. When this enzyme is inhibited, blood vessels relax and widen, allowing increased blood flow during sexual stimulation. This helps achieve and maintain a firm erection. Importantly, it only works when there is sexual arousal—it does not cause an automatic erection.
