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.
GLP-1 receptor agonist; liraglutide is an acylated human GLP-1 analog (97% amino acid sequence homology to endogenous human GLP-1(7-37)) that stimulates glucose-dependent insulin secretion, suppresses glucagon secretion, and delays gastric emptying.
