Cenforce is a generic form of sildenafil citrate, a well-known drug used to treat erectile dysfunction. It is available in various strengths, such as 25 mg, 50 mg, 100 mg, 150 mg, and 200 mg, and it works by increasing blood flow to the penis during sexual stimulation. The main mechanism of Cenforce is through the inhibition of an enzyme called phosphodiesterase type 5 (PDE5), which leads to the relaxation of blood vessels in the penis. This allows for increased blood flow and, consequently, an erection.
