What is Tirzepatide?
Tirzepatide is a synthetic peptide medicine that activates two incretin pathways. Brand, indication and eligibility differ between markets, so the active ingredient should not be confused with a single universal product approval.
Approved-use context
Regulators have authorised tirzepatide products for specified adults with type 2 diabetes and, under separate product authorisations in some markets, chronic weight management. It is not suitable for everyone and requires a prescription and clinical assessment.
How it works
Tirzepatide activates glucose-dependent insulinotropic polypeptide (GIP) and GLP-1 receptors. These pathways influence glucose-dependent insulin release, glucagon signalling, gastric emptying, appetite and food intake.
Formulations and schedules
Commercial products are supplied in pre-filled injection devices for subcutaneous use. Device instructions, strengths and authorised uses are product- and market-specific; users should follow their own product leaflet and clinical plan.
