Linagliptin is an inhibitor of DPP-4, an enzyme that degrades the incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). By inhibiting DPP-4 Linagliptin increases the concentrations of active incretin hormones and stimulates the release of Insulin in a glucose dependent manner and decreases the level of Glucagon in the circulation and thus regulates the glucose homeostasis. Incretin hormones are secreted at a low basal level throughout the day and levels rise immediately after meal intake. GLP-1 and GIP increase Insulin biosynthesis and secretion from pancreatic beta-cells in the presence of elevated blood glucose levels. Furthermore, GLP-1 also reduces Glucagon secretion from pancreatic alpha-cells, resulting in a reduction in hepatic glucose output.
