Sildenafil citrate, the active ingredient in Cenforce 200 mg, is a phosphodiesterase type 5 (PDE5) inhibitor. It works by blocking the PDE5 enzyme, which regulates blood flow in the penis. This inhibition increases levels of cyclic guanosine monophosphate (cGMP), leading to relaxation of smooth muscle and improved blood flow, facilitating an erection when sexually aroused.
