Abstract
-
▲ Vascular dementia (VaD), caused by stroke or small vessel disease, is the second most common form of dementia after Alzheimer’s disease (AD). Donepezil, an acetylcholinesterase inhibitor currently indicated for use in patients with mild to moderate AD, has recently been evaluated in VaD.
-
▲ Donepezil 5 or 10mg once daily provided significant improvements in cognition, as determined by the Alzheimer’s Disease Assessment Scale-cognitive subscale (ADAS-cog), relative to placebo, after 24 weeks in patients with VaD. Pooled data from two, randomised, double-blind, phase III trials showed that the least-squares mean change from baseline score effect size for the ADAS-cog was −1.79 for donepezil 5mg once daily (p < 0.001) and −2.28 for donepezil 10mg once daily (p < 0.001) at 24 weeks (observed cases).
-
▲ Significant improvement in global functioning occurred with donepezil 5mg once daily compared with placebo (p = 0.003), but not with donepezil 10mg once daily, as measured by the Clinician’s Interview-Based Impression of Change-plus version score (pooled data, observed cases).
-
▲ Donepezil was generally well tolerated in patients with VaD. Most adverse events were mild to moderate in nature, with diarrhoea and nausea being the most common.
