REMS


Action

  • Inhibits the enzyme cyclic adenosine monophosphate (cAMP) phosphodiesterase III (PDE III), which results in increased cAMP in platelets and blood vessels, producing inhibition of platelet aggregation and vasodilation.
Therapeutic effects:
  • Reduced symptoms of intermittent claudication with improved walking distance.

Pharmacokinetics

Absorption: Slowly absorbed after oral administration.

Distribution: Unknown.

Protein Binding: 95–98% bound to plasma proteins; one active metabolite is 97.4% bound, the other is 66% bound.

Metabolism/Excretion: Extensively metabolized by the liver, two metabolites have platelet aggregation inhibitory activity; metabolites are mostly excreted by the kidneys.

Half-Life: Cilostazol and its active metabolites: 11–13 hr.
