Outline of Final Research Achievements

Cilostazol has been shown to be effective for prevention and treatment of cerebral infarction. However, there appears to be no widely accepted method appropriate for monitoring cilostazol. We attempted to establish an assay system for cilostazol monitoring, using platelet aggregation induced by arachidonic acid (AA), ADP or thrombin receptor agonist peptide (TRAP) in the presence of PGE1 which upregulates intracellular cyclic AMP.
AA-, ADP- or TRAP-induced platelet aggregation in the presence of PGE1 could give good estimate after ingestion of cilostazol. It is suggested that this system is a good tool for monitoring cilostazol. We believe this system for monitoring cilostazol can be useful for estimating the actual efficacy of cilostazol on platelet aggregation, bioavailability, and compliance for cilostazol in actual clinical settings, and hope that this method can serve as a tailor-made therapy for cilostazol.
