Overview

Dual GLP-1/GIP receptor agonist showing superior weight loss and glucose control compared to single GLP-1 agonists. Novel dual agonist mechanism.

Global Regulatory Status

Approval status across major regulatory agencies worldwide.

Note: "Unknown" status indicates that comprehensive regulatory information is not yet available in our database. This does not necessarily mean the peptide is not approved. For critical medical decisions, always verify current regulatory status with the relevant health authority.

Mechanism of Action

Activates both GLP-1 and GIP receptors, synergistically enhancing glucose-dependent insulin secretion, reducing glucagon, delaying gastric emptying, and suppressing appetite.

Pharmacokinetics: Half-Life by Administration Route

The biological half-life varies significantly depending on the route of administration. This affects dosing frequency and duration of action.

Administration Route Half-Life Clinical Implications
Subcutaneous (SC) Approximately 5 days (approximately 117 hours), allowing once-weekly administration Slower absorption, sustained release, most common route

Note: Half-life values can vary between individuals based on factors including age, metabolism, kidney/liver function, and co-administered medications.
