Cenforce 50 mg is marketed as a sildenafil product used to treat erectile dysfunction (ED). Sildenafil belongs to a group of medicines called PDE5 inhibitors. It works by increasing blood flow to the penis when sexual stimulation occurs, helping men achieve and maintain an erection. Sildenafil can improve erection firmness, maintenance, and overall sexual satisfaction in men whose ED responds to treatment. However, it does not increase sexual desire and requires sexual stimulation to work.
