Abstract:
Memantine and the Acetylcholinesterase inhibitors (AChEIs) are two classes of drugs that are used to treat patients with Alzheimer's disease. We conducted a network meta-analysis of randomized controlled trials to compare the treatment effectiveness of monotherapy or combination therapy A total of 23,707 AD patients in 76 randomized trials were identified. In patients with mild-to-moderate AD, monotherapy with donepezil, galantamine or rivastigmine were superior to placebo in enhancing cognitive functions and activities of daily living (ADL), whereas monotherapy with donepezil or memantine were superior to placebo in improving behavioral symptoms. However, combination therapy with AChEIs and memantine did not show additional benefit than monotherapy. In patients with moderate-to-severe AD, neither monotherapy nor combination therapy were superior to placebo in any domain measurement. Combination therapy with memantine and AChEIs is confirmed to have no additional benefits over monotherapy. This article is protected by copyright. All rights reserved.
