Tirzepatide

Also known as: Mounjaro, Zepbound, LY3298176, twincretin, dual GIP/GLP-1 receptor agonist

Dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist; first-in-class incretin mimetic

What it is

Tirzepatide is a first-in-class dual agonist at receptors for glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) (PMID 38388874; PMID 37070418). By simultaneously activating both incretin pathways, it improves glycemic control, reduces appetite and food intake, promotes weight loss, and exerts pleiotropic cardiometabolic effects (PMID 41923370; PMID 38994609). Population pharmacokinetic modeling shows tirzepatide follows a two-compartment model with first-order absorption and elimination, a half-life of approximately 5 days, enabling once-weekly subcutaneous dosing. Mechanistic studies suggest tirzepatide increases fat oxidation and reduces calorie intake without meaningfully impacting metabolic adaptation in humans. Additional mechanisms under investigation include anti-inflammatory effects (reduction of hsCRP and IL-6), modulation of gut microbiota and bile acid metabolism, improvement of islet cell function and insulin sensitivity, enhancement of endothelial nitric oxide synthase activity, suppression of pro-inflammatory cytokines, and improvement of lipid profiles.
