About
Sitagliptin is an oral antidiabetic medication that belongs to the class of dipeptidyl peptidase-4 (DPP-4) inhibitors. Its primary mechanism of action involves inhibiting the enzyme DPP-4, which is responsible for the rapid breakdown of incretin hormones, such as glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). By preserving these incretins, sitagliptin enhances the body's natural ability to regulate blood glucose levels. This leads to increased glucose-dependent insulin secretion from pancreatic beta cells, meaning insulin is released more effectively when blood sugar is high. Concurrently, it reduces glucagon secretion from pancreatic alpha cells, ultimately improving both fasting and postprandial hyperglycemia in patients with type 2 diabetes mellitus. It is often used when diet and exercise alone are insufficient to achieve adequate glycemic control.
