NCIt definition : A quinolinone derivative and cellular phosphodiesterase inhibitor, more specific for
phosphodiesterase III (PDE III). Although the exact mechanism of action of is unknown,
cilostazol and its metabolites appears to inhibit PDE III activity, thereby suppressing
cyclic adenosine monophosphate (cAMP) degradation. This results in an increase in
cAMP in platelets and blood vessels, leading to inhibition of platelet aggregation
and vasodilation.;
