Abstract

Rivastigmine is a cholinesterase inhibitor that is widely used for the treatment of mild to moderate Alzheimer's disease,(1,3) This systematic review aims to evaluate the evidence on the efficacy and safety of rivastigmine compared with placebo in patients with Alzheimer's disease. We searched the Cochrane Library, PubMed, Web of Science, and other databases for randomized controlled trials that compared rivastigmine with placebo in patients with Alzheimer's disease. We assessed the risk of bias, extracted the data, and performed meta-analyses using the random-effects model. The primary outcomes were cognitive function, activities of daily living, global clinical impression, and adverse events. Thirteen studies involving 7,398 patients were included. The results showed that rivastigmine was superior to placebo in improving cognitive function (standardized mean difference (SMD) = -0.20, 95% confidence interval (CI) = -0.25 to -0.15), activities of daily living (SMD = 0.20, 95% CI = 0.15 to 0.25), and global clinical impression (odds ratio (OR) = 1.47, 95% CI = 1.25 to 1.72). However, rivastigmine was also associated with a higher risk of adverse events, especially gastrointestinal symptoms, weight loss, and dizziness. The quality of evidence was moderate to low due to heterogeneity, imprecision, and risk of bias. In conclusion, rivastigmine may have a modest benefit for patients with mild to moderate Alzheimer's disease, but the clinical significance and cost-effectiveness of this benefit need to be weighed against the potential harm and burden of adverse events.
