Mechanism of action
Dulaglutide is an analogue of glucagon-like peptide-1 (GLP-1), an incretin hormone linked to a modified human Ig G4 fragment and act as GLP-1 receptor agonist. Activation of GLP-1 stimulates insulin release by increasing intracellular cyclic AMP (cAMP) in pancreatic beta cells and suppression of glucagon secretion in a glucose-dependent manner. It also slows gastric emptying thus reduces postprandial glucose (PPG) concentration.
