Filitra 20 mg is a medication used to treat erectile dysfunction (ED), and its active ingredient is Vardenafil, which is a PDE5 inhibitor (phosphodiesterase type 5 inhibitor). Similar to other ED medications like Viagra (Sildenafil) and Cialis (Tadalafil), it helps increase blood flow to the penis, making it easier to achieve and maintain an erection when sexually aroused.
