What is Tirzepatide?

Tirzepatide is a groundbreaking medication used for type 2 diabetes and chronic weight management. It is the active ingredient in the brand-name drugs Mounjaro and Zepbound.

A New Class: Dual Agonist

Unlike previous weight loss medications (like Ozempic or Wegovy) which mimic only one hormone (GLP-1), Tirzepatide mimics two:

• GLP-1 (Glucagon-like peptide-1): Reduces appetite and slows digestion.
• GIP (Glucose-dependent insulinotropic polypeptide): Improves insulin sensitivity and works synergistically with GLP-1 to enhance metabolic effects.

This dual action is why Tirzepatide has shown superior weight loss results in clinical trials compared to GLP-1 agonists alone.
