About
Sitagliptin is an oral dipeptidyl peptidase-4 (DPP-4) inhibitor prescribed for the management of type 2 diabetes mellitus. Its therapeutic action stems from inhibiting the enzyme DPP-4, which plays a crucial role in the inactivation of incretin hormones, such as glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). By preventing the breakdown of these naturally occurring hormones, sitagliptin effectively increases their active concentrations. This leads to enhanced glucose-dependent insulin secretion from the pancreatic beta cells and a reduction in glucagon secretion from the pancreatic alpha cells, particularly after meals. The net effect is a significant improvement in glycemic control, characterized by lower fasting and postprandial blood glucose levels. It is typically used as an adjunct to diet and exercise, either alone or in combination with other antidiabetic medications, providing a targeted approach to glucose regulation.
