Semaglutide demonstrates the greatest mean reduction in body weight among GLP-1RAs in psychiatric populations, significantly outperforming placebo and showing superior efficacy to liraglutide and exenatide in network meta-analysis.

Among GLP-1 medications, semaglutide (oral) appears to produce the most significant weight loss in patients with psychiatric conditions, averaging over 6 kg (13 lbs) loss. It is more effective than liraglutide or exenatide in this group. However, data is limited to one study, so discuss availability and cost with your provider.
