Cilostazol is a medication used in the alleviation of the symptom of intermittent claudication in individuals with peripheral vascular disease. It is manufactured by Otsuka Pharmaceutical Co. under the trade name Pletal. Although drugs similar to cilostazol have increased the risk of death in patients with congestive heart failure, studies of significant size have not addressed people without the disease.

Cilostazol (OPC-13013) is a 2-oxo-quinoline derivative with antithrombotic, vasodilator, antimitogenic and cardiotonic properties. The vasodilatory and antiplatelet actions of cilostazol are due mainly to the inhibition of phosphodiesterase 3 (PDE3) and subsequent elevation of intracellular cAMP levels. Cilostazol inhibits platelet aggregation. Cilostazol also possesses the ability to inhibit adenosine uptake. Elevation of interstitial adenosine by cilostazol in the heart is shown to reduce increases in cAMP caused by the PDE3-inhibitory action of cilostazol, thus attenuating the cardiotonic effects. Cilostazol is reported to inhibit smooth muscle cell proliferation. Cilostazol relaxes vascular smooth muscle and causes vasodilatation. Cilostazol inhibits the cytokine-induced expression of monocyte chemoattractant protein-1 (MCP-1). Cilostazol reduced plasma triglycerides and raised plasma HDL-cholesterol .

Cilostazol (clinically used doses; p.o.; for 2 weeks) could alleviate CCl4 -induced hepatic fibrogenesis in vivo, presumably due to its direct effect to suppress HSC activation.
Cilostazol (intraperitoneal injection; 10 mg/kg; 7 consecutive days after ischemia) attenuates neurological dysfunctions, brain atrophy and infarct volume, and inhibits astrocyte proliferation/glial scar formation and accelerated the angiogenesis in the ischemic boundary zone 7 and 28 days after ischemia.
