Usage |
Alogliptin benzoate is a selective inhibitor of dipeptidyl peptidase-4 (DPP-4). Eating stimulates the small intestine to secrete elevated concentrations of incretins, such as glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), into the bloodstream. These hormones cause islet beta cells to release insulin in a glucose-dependent manner, but these hormones are inactivated by the DPP-4 enzyme within minutes. Inhibition of DPP-4 activity by alogliptin slows the inactivation of these incretins, thereby increasing blood concentrations of these hormones and reducing fasting and postprandial blood glucose in a glucose-dependent manner in patients with type II diabetes.
