Summary
Sildenafil citrate, a selective 5-phosphodiesterase inhibitor, enhances nitric oxide dependent pulmonary vasodilation mediated by cyclic guanosine monophosphate by inhibiting the decomposition of cyclic guanosine monophosphate. In addition to direct dilation of pulmonary vessels, it can also prevent or reverse vascular remodeling. It is used for impotence patients with erectile dysfunction.
