Sildenafil citrate is used to treating erectile dysfunction and pulmonary arterial hypertension (PAH). It works by inhibiting the enzyme, (cGMP) cyclic guanosine monophosphate-specific phosphodiesterase type 5 (PDE5). This enzyme works by promoting degradation of cGMP that regulates blood flow in the penis. The erection process is accompanied with sexual stimulation that releases nitric oxide into the penis. It reacts inside penis and form an enzyme cyclic guanosine monophosphate (cGMP). It loosens and relaxes the arterial wall of the penis and thus, erection is created. Once the artery of the penis becomes loose, it helps in easy engorgement of blood. The arteries are swollen, an erection is created.

Another enzyme called phosphodiesterase-5 is also present in the penis that helps in achieving erection. This enzyme degrades and reduces cyclic guanosine monophosphate within penis. This degradation is essential; else there will be constant erection.
