Is Mounjaro a type of insulin?

Mounjaro (tirzepatide) is not a type of insulin. It is a medication for the treatment of type 2 diabetes that belongs to a class of drugs known as dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonists. Mounjaro works by mimicking the effects of natural hormones that help control blood sugar levels, thereby improving glycemic control in adults with type 2 diabetes. It does this by stimulating insulin secretion and reducing glucagon secretion in a glucose-dependent manner, among other mechanisms. While it is used to manage blood sugar levels, it differs from insulin therapies which directly replace or supplement the body's insufficient insulin production in the treatment of diabetes.
