Filitra 40 mg is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient vardenafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. Like sildenafil (the active ingredient in Viagra) and tadalafil (the active ingredient in Cialis), vardenafil works by increasing blood flow to the penis, which can help men achieve and maintain an erection when sexually aroused.
