Detailed Description of Business Cenforce 100 is a popular medication used to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate as its active ingredient, the same component found in Viagra. Sildenafil belongs to a class of drugs called PDE5 inhibitors, which help improve blood flow to the penis, enabling men with ED to achieve and maintain an erection during sexual arousal. By blocking this enzyme, Sildenafil allows the blood vessels in the penis to relax and expand, leading to increased blood flow and making it easier to achieve and maintain an erection.
