A Comprehensive Guide to Mounjaro in the UK.
Learn about Mechanism, Cost, Savings Tips, and Precautions of Mounjaro.
What is Mounjaro?
Mounjaro (generic name: tirzepatide) is a breakthrough dual hormone agonist developed by Eli Lilly and Company. It has been approved in the UK for the treatment of type 2 diabetes and has recently been approved for weight loss. It uniquely targets GLP-1 and GIP receptors to regulate appetite, blood sugar and fat metabolism. Unlike single hormone drugs such as Wegovy (semaglutide), Mounjaro's dual mechanism of action brings excellent weight loss effects, making it stand out in the obesity treatment market.
How does Mounjaro work?
Mounjaro mimics the effects of two natural hormones: GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide). Together, they work to:
Suppress appetite by signaling fullness to the brain.
Slow stomach emptying, prolonging feelings of fullness after meals.
Enhance insulin sensitivity, improving blood sugar control.
Reduce fat storage by optimizing metabolic processes.
