Cilostazol is a selective type-3 phosphodiesterase inhibitor that ameliorates accumulation of amyloid-¦Â and has prevented cognitive decline in rodent models. Furthermore, cilostazol is known to suppress platelet aggregation, protect vascular endothelia, dilate vessels, and increase cerebral blood flow. Beneficial effects have also been shown in observational cohort studies, demonstrating the need for a prospective clinical trial %K Alzheimer's disease %K Cilostazol %K Clearance %K Clinical trial %K Drug repositioning %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5651350/
