Cenforce pills are primarily used to treat erectile dysfunction (ED) in men. The active ingredient in Cenforce is Sildenafil Citrate, the same active ingredient found in Viagra. Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor that works by improving blood flow to the penis, which helps men achieve and maintain an erection when sexually aroused. Cenforce is most commonly prescribed for men who have difficulty achieving or maintaining an erection during sexual activity, a condition known as erectile dysfunction. It helps relax the blood vessels in the penis, allowing for increased blood flow during sexual stimulation, making it easier to get and maintain an erection.
