Clinical reports indicate that cardiotoxicity due to donepezil can occur after coadministration with cilostazol. We speculated that the concentration of donepezil in heart tissue might be increased as a result of interaction with cilostazol at efflux transporters such as P-glycoprotein (P-gp, ABCB1) and breast cancer resistance protein (BCRP, ABCG2), which are expressed in many tissues includin...
BACKGROUND Findings from observational studies have suggested a delay in nursing home placement with dementia drug treatment, but findings from a previous randomised trial of patients with mild-to-moderate Alzheimer's disease showed no effect. We investigated the effects of continuation or discontinuation of donepezil and starting of memantine on subsequent nursing home placement in patients wi...
Background: Progressive neurodegeneration of nervous system as well as learning and memory disorders is characteristics of Alzheimer’s disease. Drug delivery is one of the research aspects for improving treatment of diseases. Chitosan nanoparticles were used for Donepezil transportation and its effect on dimproving amnesia was investigated. Materials and Methods: In this experimental study, 13...
The acetylcholinesterase (AChE) inhibitor donepezil is also a sigma1 receptor agonist. We examined whether donepezil binds to sigma1 receptors in the living human brain after a single oral administration. Dynamic positron emission tomography (PET) data acquisition using the selective sigma1 receptor ligand [11C]SA4503 was performed to evaluate quantitatively the binding of [11C]SA4503 to sigma1...
INTRODUCTION Donepezil is indicated for the symptomatic treatment of mild to moderate Alzheimer's disease. It is a specific and reversible inhibitor of acetylcholinesterase (AChE); by increasing levels of available acetylcholine, donepezil may compensate for the loss of functioning cholinergic brain cells. AIMS This review evaluates the clinical impact of donepezil by assessing randomized con...
OBJECTIVE To compare the outcome of donepezil treatment in ethnically diverse Alzheimer disease (AD) patients with ethnically diverse AD patients who did not receive donepezil. METHODS Patients meeting NINCDS-ADRA criteria for probable or possible AD from a consortium of California sites were systematically followed for at least 1 year in this prospective, observational study. Their treatment...
Improved understanding of neurobehavior in normal aging, Alzheimer's disease, and late-life depression makes early detection of neurodegenerative conditions possible. Primary care physicians can screen patients' mental status and mood states with simple in-office tests. When screening results or the clinical picture is ambiguous or complex, neuropsychological evaluation is useful in making an e...
A wide range of evidence show that acetylcholinesterase (AChE) inhibitors can interfere with the progression of Alzheimer's Disease (AD). The successful development of these compounds was based on a well-accepted theory that the decline in cognitive and mental functions associated with AD is related to the loss of cortical cholinergic neurotransmission. The earliest known AChE inhibitors, namel...
The 5-HT6 receptor is a promising target for cognitive disorders, in particular for Alzheimer's disease (AD). The high affinity and selective 5-HT6 receptor antagonist idalopirdine (Lu AE58054) is currently in development for mild-moderate AD as adjunct therapy to acetylcholinesterase inhibitors (AChEIs). We studied the effects of idalopirdine alone and in combination with the AChEI donepezil o...
Insulin-like growth factor-I (IGF-I) exerts beneficial effects on cognitive function. The selective acetylcholinesterase inhibitor donepezil increases serum IGF-I levels in elderly subjects. Because stimulation of sensory neurons induces IGF-I production by releasing calcitonin gene-related peptide (CGRP) in the mouse brain, we hypothesized that donepezil increases IGF-I production by sensory n...
