Filitra is a medication used to treat erectile dysfunction (ED) in men. It contains vardenafil, a PDE5 inhibitor, which works by increasing blood flow to the penis to help achieve and maintain an erection during sexual activity. Vardenafil, the active ingredient in Filitra, helps by blocking the enzyme PDE5. This enzyme typically restricts blood flow to the penis. By inhibiting PDE5, Filitra allows blood vessels to relax, improving blood flow to the penis, which is essential for getting and maintaining an erection during sexual arousal.
