Pharmacology
Sotagliflozin is a dual inhibitor of SGLT2 and SGLT1; SGLT2 inhibition reduces renal reabsorption of glucose and sodium (lowering cardiac pre- and afterload and downregulating sympathetic activity), while SGLT1 inhibition reduces intestinal absorption of glucose and sodium.
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.
