Filitra 20 mg is a medication that contains Vardenafil, which is a PDE5 inhibitor similar to other erectile dysfunction (ED) treatments like Viagra (Sildenafil) and Cialis (Tadalafil). It works by increasing blood flow to the penis, helping men achieve and maintain an erection when sexually aroused. Filitra (Vardenafil) works by blocking the enzyme phosphodiesterase type 5 (PDE5), which is responsible for breaking down a substance called cGMP in the smooth muscle of the penis.
