MOUNJARO

TIRZEPATIDE G-Protein-linked Receptor Interactions
Metabolic Approved 2022-05-13

Mounjaro (tirzepatide) is indicated to improve glycemic control in patients with type 2 diabetes mellitus. It is approved for use in adults and pediatric patients aged 10 years and older as an adjunct to diet and exercise. The medication functions as a dual receptor agonist, targeting specific pathways involved in glucose metabolism.

How MOUNJARO Works

Tirzepatide selectively binds to and activates both glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. By activating these targets, the drug enhances insulin secretion and reduces glucagon levels in a glucose-dependent manner. It also contains a C20 fatty diacid that facilitates albumin binding to prolong the medication's half-life. These biological actions collectively improve the body's ability to regulate blood sugar.

MOUNJARO Boxed Warning

RISK OF THYROID C-CELL TUMORS In both male and female rats, tirzepatide causes dose-dependent and treatment-duration-dependent thyroid C-cell tumors at clinically relevant exposures. It is unknown whether MOUNJARO causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans as human relevance of tirzepatide-induced rodent thyroid C-cell tumors has not been determined [see Warnings and Precautions ( 5.1 ) and Nonclinical Toxicology ( 13.1 )]. MOUNJARO is contraindicated in...

MOUNJARO Target & Pathway

Pro

Target

GLP-1 (Glucagon-Like Peptide-1) Incretin Receptor

A hormone released after eating that stimulates insulin secretion, suppresses glucagon, slows gastric emptying, and promotes satiety. GLP-1 receptor agonists mimic these effects, improving blood sugar control and promoting weight loss in diabetes and obesity.

5 other drugs also target GLP-1. Compare mechanisms, indications, and trial activity.

Drug = Competitor name Company = Manufacturer N indic. = FDA-approved indications → Date = Patent/exclusivity expiry

Competitors share the same molecular target (GLP-1). Earlier expiry dates signal biosimilar/generic opportunities.
