Used in the management of type 2 diabetes mellitus, this compound helps regulate blood glucose levels by enhancing the body's own insulin release in a glucose-dependent manner. It works by inhibiting the enzyme DPP-4, which breaks down incretin hormones like GLP-1 and GIP. By preserving these hormones, it increases insulin secretion after meals and reduces excessive glucose production by the liver. It is often prescribed as monotherapy or in combination with other antidiabetic agents such as metformin. Due to its low risk of hypoglycemia and weight-neutral profile, it is suitable for long-term glycemic control in adult patients.
