Mounjaro Injection (pronounced mown-JAR-oh) is a once-weekly injectable medication designed to help manage type 2 diabetes and support weight loss. It contains Tirzepatide, a novel active ingredient that mimics two natural hormones — GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide) — both of which play key roles in regulating blood sugar and appetite.
Unlike traditional diabetes medications that target a single pathway, Mounjaro’s dual-action mechanism makes it stand out as a cutting-edge treatment in metabolic health management.
How Does Mounjaro Work?
The science behind Mounjaro lies in how it interacts with the body’s hormonal systems:
| Function | Effect of Mounjaro |
|---|---|
| Blood Sugar Control | Enhances insulin release and reduces glucose production by the liver. |
| Appetite Regulation | Signals the brain to reduce hunger and cravings. |
| Weight Reduction | Slows digestion and promotes a feeling of fullness, reducing calorie intake. |
| Metabolic Health | Improves insulin sensitivity and supports long-term metabolic balance. |
By targeting both GLP-1 and GIP receptors, Mounjaro offers superior glucose control and weight reduction compared to other single-action GLP-1 drugs.
