The main purpose of Cenforce tablets is to treat male erectile dysfunction (ED). The inability to obtain or maintain an erection strong enough for fulfilling sexual activity is the hallmark of erectile dysfunction, often known as impotence. The active component of Cenforce, sildenafil, is a member of a family of drugs known as phosphodiesterase type 5 (PDE5) inhibitors, which increase blood flow to the penis during intercourse.
