Vildagliptin 0-12 gastric inhibitory polypeptide Homo sapiens 235-238 18269436-4 2008 Mechanistic studies of vildagliptin performed to characterise the effects of DPP-4 inhibition on pancreatic islet function and glucose metabolism have found that vildagliptin produces dose-dependent reductions in DPP-4; these result in persistent levels of active GLP-1 and GIP in the circulation leading to improved beta-cell sensitivity to glucose and glucose-dependent insulin secretion, and improved alpha-cell sensitivity to glucose and reduction in inappropriate glucagon secretion.
