Cenforce 120 mg contains Sildenafil Citrate, the same active ingredient found in Viagra, and works by inhibiting the action of the phosphodiesterase type 5 (PDE5) enzyme. By blocking PDE5, Cenforce increases the levels of cyclic GMP (cGMP), which relaxes the muscles and dilates blood vessels in the penis, allowing for improved blood flow when sexually aroused.
