Description
Retatrutide works in the treatment of obesity by targeting three different hunger-regulating hormones GIP, GLP-1, and Glucagon. GIP (gastric inhibitory peptide or glucose-dependent insulinotropic polypeptide) is an incretin hormone that is released from the gut after eating.
It stimulates the beta-cells in the pancreas to secrete insulin. GLP-1 (glucagon-like peptide-1) is also an incretin hormone that stimulates beta-cells to secrete insulin. Glucagon is a hormone secreted from the alpha cells in the pancreas. It stimulates glucose production in the liver and helps maintain adequate plasma glucose concentrations.
The drug has been nicknamed ‘triple G’ because it is an agonist of all three receptors.
