Cenforce 100 mg is a medication used to treat erectile dysfunction (ED) in men in Canada, the US, or other countries. It contains the active ingredient Sildenafil Citrate, a phosphodiesterase type 5 (PDE5) inhibitor. This medication works by relaxing the blood vessels in the *****, allowing more blood to flow into the area and helping men achieve and maintain an erection. Cenforce 100 mg is taken orally, typically 30 minutes to 1 hour before sexual activity. Cenforce 100 mg contains Sildenafil Citrate, a phosphodiesterase type 5 (PDE5) inhibitor. When a man is sexually stimulated, the body releases a chemical called nitric oxide that causes the blood vessels in the ***** to relax and widen.
