How Mounjaro (Tirzepatide) Works
Tirzepatide activates two incretin receptors:
GLP-1 Receptor
- Increases insulin secretion when blood sugar is high
- Reduces glucagon release
- Slows gastric emptying
GIP Receptor
- Enhances insulin sensitivity
- Improves glucose metabolism
By targeting both pathways, Mounjaro provides enhanced glycemic control and may also promote weight loss through appetite regulation and increased satiety.
