Abstract
Background
Antipsychotic-related overweight and metabolic dysregulation are highly prevalent among patients with severe mental illness. Although glucagon-like peptide-1 receptor agonists (GLP-1RAs) have demonstrated substantial metabolic benefits in the general population, their efficacy and safety in antipsychotic-treated patients remain unclear. This review aimed to systematically evaluate the efficacy and safety of GLP-1RAs in patients with antipsychotic-related overweight and metabolic dysregulation.
Methods
We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) evaluating GLP-1RAs in adults receiving antipsychotic treatment. PubMed, Web of Science, Embase, MEDLINE, the Cochrane Library, and ClinicalTrials.gov were searched from inception to September 13, 2026. Primary outcomes included changes in body weight, body mass index (BMI), HbA1c, and total cholesterol. Random-effects models were used to pool mean differences (MDs) and risk ratios (RRs). This study was registered with PROSPERO (CRD420261290294).
