BACKGROUND Clinical trials have shown the benefits of cholinesterase inhibitors for the treatment of mild-to-moderate Alzheimer's disease. It is not known whether treatment benefits continue after the progression to moderate-to-severe disease. METHODS We assigned 295 community-dwelling patients who had been treated with donepezil for at least 3 months and who had moderate or severe Alzheimer'...
a mixture of acetaminophen, diphenhydramine hydrochloride and pseudoephedrine hydrochloride is used for the symptomatic treatment of common cold. in this study, a derivative spectrophotometric method based on zero-crossing technique was proposed for simultaneous determination of acetaminophen, diphenhydramine hydrochloride and pseudoephedrine hydrochloride. determination of these drugs was perf...
Cerebral blood flow (CBF) was assessed during a verbal recall task using [(15)O]water positron emission tomography (PET) in older adults with mild cognitive deficits participating in a placebo-controlled donepezil trial. The placebo group demonstrated reduced CBF in the left frontal and temporal regions over the 6-month period, while those receiving donepezil did not. The placebo group's perfor...
AIM The aim of this study was to evaluate the pharmacokinetic profile of donepezil HCl (5 mg) in patients with impaired hepatic function, following the administration of single oral doses. METHODS This was an open-label, non-randomized study comparing the pharmacokinetic profile of donepezil in male volunteers with chronic compensated cirrhosis of the liver (n = 10) to that in healthy age- an...
PURPOSE Ginkgo extract EGb 761 and cholinesterase inhibitors have been shown to be effective in the treatment of dementia patients. In addition to neuroprotective effects, Ginkgo extract EGb 761 has been reported to elevate brain levels of certain neurotransmitters such as dopamine, noradrenaline, and acetylcholine. In the present study, we investigated the impact of EGb 761, donepezil and the ...
The effects of yokukansan and donepezil on learning disturbance and aggressiveness were examined in amyloid β protein (Aβ)-injected mice. Intellicage tests showed that both yokukansan and donepezil ameliorated Aβ-induced learning disturbance, but the ameliorating effect of donepezil was not enhanced by concomitant administration of yokukansan. On the other hand, a social interaction test showed...
Clinical reports indicate that cardiotoxicity due to donepezil can occur after coadministration with cilostazol. We speculated that the concentration of donepezil in heart tissuemight be increased as a result of interactionwith cilostazol at efflux transporters suchasP-glycoprotein (P-gp, ABCB1) and breast cancer resistance protein (BCRP, ABCG2), which are expressed inmany tissues including the...
A considerable number of patients with breast cancer complain of cognitive impairment after chemotherapy. In this study, we showed that donepezil enhanced memory function and increased brain glucose metabolism in a rat model of cognitive impairment after chemotherapy using behavioral analysis and positron emission tomography (PET). We found that chemotherapy affected spatial learning ability, r...
To determine if donepezil, an acetylcholinesterase (AChE) inhibitor, improved the assimilation of cognitive training by older adults with memory complaints, we gave 168 nondemented, community-dwelling volunteers with memory complaints either 5 mg of donepezil (Aricept) or placebo daily for 6 weeks in a randomized, double-blind, placebo-controlled trial. The dosage rose to 10 mg daily for anothe...
