Cilostazol for Cellular Phosphodiesterase Inhibitor

Cilostazol, a quinolinone derivative, is a cellular phosphodiesterase inhibitor, more specific for phosphodiesterase III (PDE III). Cilostazol inhibits platelet aggregation and widens arteries (direct arterial vasodilator). Its main effects are dilation of the arteries supplying blood to the legs and decreasing platelet coagulation.
