Cilostazol Specifications

Cilostazol Description

Cilostazol is a quinolinone derivative first developed as an anti-thrombotic agent, inhibiting ADP-dependent platelet aggregation. It regulates cell proliferation, stimulates cyclic adenosine monophosphate (cAMP) level, and induces cyclic AMP-dependent protein kinase. This is mediated by selective and specific inhibition of cyclic nucleotide phosphodiesterase  (IC50 = 200 nM). Because of its effects on platelets, cilostazol is useful in various conditions, including peripheral artery disease, stroke, and post-stent stenosis. It is metabolized to products that also affect platelet aggregation by cytochrome P450 (CYP) isoforms CYP3A4, CYP3A5, and CYP1B1.

Cilostazol is an antiplatelet drug and a vasodilator. It works by stopping blood cells called platelets from sticking together.

Cilostazol Applications

• Used to treat chronic arterial disease and intermittent claudication
• Used to reduce Madin–Darby cell line (MDCK) proliferation through c-Myc down-regulation
• Used for secondary stroke prevention
