Manforce 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, the same active ingredient found in pill. Sildenafil works by increasing blood flow to the pill, helping men achieve and maintain an erection when sexually aroused. Sildenafil, the active ingredient, is a PDE5 inhibitor, which means it blocks the enzyme phosphodiesterase type 5 (PDE5). PDE5 breaks down a molecule called cGMP, which is responsible for relaxing smooth muscle and dilating blood vessels in the pill. https://www.genericday.com/manforce-100-mg.html
