Cenforce 150 mg is marketed as a sildenafil-based product for men experiencing erectile dysfunction (ED). Sildenafil belongs to a group of medicines called PDE5 inhibitors. It works by increasing blood flow to the penis during sexual stimulation, helping some men achieve and maintain an erection. However, 150 mg is higher than the usual maximum recommended single dose of sildenafil for ED. Taking more sildenafil than recommended does not necessarily improve erectile function and may increase the risk of side effects.
