Tirzepatide
Dual GIP and GLP-1 Receptor Agonist
Tirzepatide is a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist. Available as FDA-approved Mounjaro® for Type 2 diabetes and Zepbound® for weight management and obstructive sleep apnea. It provides superior weight loss and glycemic control compared to single-pathway medications through its unique dual mechanism of action.
