cenforce 120mg is a potent drug that is a safe and effective treatment for erectile dysfunction (ED). It is a phosphodiesterase inhibitor that increases blood flow into the penis during sexual stimulation. Sildenafil citrate is the active ingredient of this medicine. It inhibits the PDE-5 enzyme, allowing a higher concentration of cGMP hormones in the body. This results in the relaxation of the penile muscles, thereby drawing more blood to provide a firm erection.
