Pharmacology
Kombiglyze XR combines saxagliptin, a competitive DPP4 inhibitor that slows incretin hormone (GLP-1, GIP) inactivation to enhance glucose-dependent insulin release and suppress glucagon, and metformin HCl, a biguanide that decreases hepatic glucose production, reduces intestinal glucose absorption, and improves peripheral insulin sensitivity.
Dulaglutide is a human GLP-1 receptor agonist with 90% amino acid sequence homology to endogenous human GLP-1 (7-37) that activates the GLP-1 receptor in pancreatic beta cells, stimulating glucose-dependent insulin release, decreasing glucagon secretion, and slowing gastric emptying.
