Cilostazol: A Selective Inhibitor of Cyclic Nucleotide Phosphodiesterase 3 (PDE3)

Cilostazol is originally developed as a selective inhibitor of cyclic nucleotide phosphodiesterase 3 (PDE3). PDE3 inhibition in platelets and vascular smooth muscle cells is expected to provide an antiplatelet effect and vasodilatation, with therapeutic focus on cAMP. Recently, it has been reported that cilostazol is effective in vascular dementia associated with a cerebral ischemia. (The product is for research purpose only.)
