Filitra 40 mg is a medication that contains Vardenafil, which is used to treat erectile dysfunction (ED) in men. Vardenafil works in a similar way to other PDE5 inhibitors like sildenafil (Viagra) and tadalafil (Cialis) by enhancing blood flow to the penis, which helps men achieve and maintain an erection when sexually stimulated. Vardenafil is a PDE5 inhibitor that works by blocking the PDE5 enzyme, which normally breaks down cGMP, a substance that helps relax the blood vessels in the penis. By inhibiting this enzyme, Vardenafil allows for increased blood flow to the penis during sexual stimulation, aiding in achieving an erection.
