Sildenafil citrate inhibits the enzyme PDE5, which is responsible for the degradation of cyclic guanosine monophosphate (cGMP) in the corpus cavernosum of the penis. By inhibiting PDE5, sildenafil citrate helps to maintain high levels of cGMP, leading to smooth muscle relaxation and increased blood flow to the penis, resulting in an erection.
