Cenforce is a widely used medication for treating erectile dysfunction (ED) in adult men. It contains the active ingredient Sildenafil, which belongs to a group of medicines called PDE5 inhibitors. These drugs work by improving blood flow to the penis during sexual stimulation, helping men achieve and maintain a firm erection suitable for sexual activity. Sildenafil in Cenforce blocks the PDE5 enzyme, which normally limits blood flow in the penile tissues. When this enzyme is inhibited, blood vessels relax and expand, allowing more blood to flow into the penis during sexual arousal.
