Sildenafil is a selective inhibitor of the type 5 cGMP phosphodiesterase (PDE5 inhibitor) which catalyzes the hydrolysis of 3',5'-cyclic guanosine monophosphate (cGMP). As a PDE5 inhibitor, Sildenafil has been reported to enhance neuro-, synapto- and angiogenesis in rat models of stroke and also is reported to be a mild vasodilator. Sildenafil has also been shown to prevent indomethacin-induced small intestinal ulceration formation through an NO/cGMP- dependent mechanism.
