Cilostazol and atherogenic dyslipidemia: a clinically relevant effect?

INTRODUCTION: Cilostazol is a reversible, selective inhibitor of PDE3A able to significantly improve walking distance in patients with intermittent claudication. However, beyond its antiplatelet and vasodilator properties, cilostazol seems to have significant effects on atherogenic dyslipidemia. AREAS COVERED: The effects of cilostazol on plasma lipids, lipoproteins, apolipoproteins and postprandial lipemia are reviewed. A literature search (using Medline and Scopus) was performed up to 24 October 2010. The authors also manually reviewed the references of selected articles for any pertinent material. EXPERT OPINION: Cilostazol is able to significantly lower plasma triglyceride levels, with a concomitant increase in high-density lipoprotein (HDL) cholesterol concentrations. Additional effects on pro-atherogenic lipoproteins and apolipoproteins include those on remnant-like particles, HDL subclasses, apolipoprotein B and postprandial lipemia. Cilostazol can improve the pro-atherogenic lipid profile in patients with peripheral arterial disease or type 2 diabetes. Further studies are needed to establish whether cilostazol treatment exerts clinically relevant effects on atherogenic dyslipidemia in high-risk patients.
