​Cenforce tablets are medications primarily used to treat erectile dysfunction (ED) in men. They contain sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor that enhances blood flow to the penis during sexual stimulation, aiding in achieving and maintaining an erection. Sildenafil inhibits the PDE5 enzyme, which breaks down cGMP, a chemical that promotes relaxation of smooth muscle and increased blood flow.
