Vilitra 40 mg is a higher dose of Vardenafil, a PDE5 inhibitor used to treat erectile dysfunction (ED) in men. Like other PDE5 inhibitors such as Sildenafil (Viagra) and Tadalafil (Cialis), Vardenafil works by increasing blood flow to the penis during sexual arousal, helping men achieve and maintain an erection. Vardenafil, the active ingredient in Vilitra 40 mg, works by inhibiting the PDE5 enzyme. This enzyme usually breaks down cGMP, which is responsible for relaxing the blood vessels and improving blood flow to the penis.
