Overview
Type 2 diabetes, chronic weight management, and obstructive sleep apnea

Tirzepatide is a dual-action peptide approved by the FDA as Mounjaro for type 2 diabetes and Zepbound for weight management. In December 2024, Zepbound became the first and only medication approved for moderate-to-severe obstructive sleep apnea (OSA) in adults with obesity. 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.
