Sildenafil was originally developed by Pfizer within the late 1980s as a treatment for angina pectoris, a situation characterized by chest ache.

Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor. When a man is sexually aroused, nitric oxide is released in the corpus cavernosum of the penis. Nitric oxide stimulates the production of cyclic guanosine monophosphate (cGMP), which relaxes smooth muscle tissue and permits blood to circulate into the penis, resulting in an erection. PDE5 breaks down cGMP, however Sildenafil inhibits this process, allowing cGMP to construct up and prolong the erection's duration.
