The main purpose of the drug cenforce is to cure erectile dysfunction (ED) in males. Its active component, sildenafil citrate, is a strong inhibitor of the phosphodiesterase type 5 (PDE5) enzyme. During sexual stimulation, sildenafil helps to enhance blood flow to the penis by inhibiting PDE5, which in turn facilitates erections.

Cenforce 50 is a dilution of the drug that contains one tablet of sildenafil citrate. People who need a softer effect or who are more sensitive to the drug may be administered this lesser dosage. Like other sildenafil-containing drugs, Cenforce is usually given orally, ideally between 30 and 1 hour prior to planned sexual activity.
