The main component of Cenforce 150, sildenafil citrate, works by enhancing the blood flow allowing for improved erectile function. It achieves this by inhibiting the PDE5 enzyme, which is responsible for the degradation of cyclic guanosine monophosphate (cGMP). By blocking PDE5, Cenforce 150 helps increase the levels of cGMP, leading to smooth muscle relaxation, increased blood flow, and ultimately, a firm and sustained erection.
