Cenforce 200 is a medication primarily used to treat erectile dysfunction (ED) in men. It contains 200 mg of Sildenafil Citrate, which is the same active ingredient found in the well-known medication Viagra. Sildenafil is classified as a PDE5 inhibitor, meaning it works by blocking the enzyme phosphodiesterase type 5 (PDE5), which can restrict blood flow to the penis. By inhibiting this enzyme, Cenforce 200 helps to increase blood flow, allowing men to achieve and maintain an erection in response to sexual stimulation.
