Tirzepatide

Also known as: Mounjaro, Zepbound

Brand names: Mounjaro, Zepbound

Overview
Type 2 diabetes and chronic weight management

Tirzepatide is a dual-action peptide approved by the FDA as Mounjaro for type 2 diabetes and Zepbound for weight management. It is the first medication to target both GIP and GLP-1 receptors simultaneously. In the SURMOUNT-1 trial, participants achieved an average weight loss of 22.5% over 72 weeks. This dual mechanism appears to provide superior glycemic control and weight loss compared to GLP-1-only agonists.
