What is Tirzepatide?
- Tirzepatide is a synthetic peptide that works as a dual receptor agonist, activating both GIP and GLP-1 receptors in the body. It's approved for treating type 2 diabetes (as Mounjaro) and chronic weight management (as Zepbound). It's administered as a once-weekly injection and represents the first medication in this dual-agonist class.
- Tirzepatide works by enhancing insulin secretion when blood sugar is high, reducing appetite, slowing digestion, and improving how the body uses insulin. Clinical trials have shown it can produce substantial weight loss of 15-22% of body weight while significantly improving blood sugar control.
