Gosogliptin is primarily used in the management of type 2 diabetes mellitus. It functions as a dipeptidyl peptidase-4 (DPP-4) inhibitor, which helps regulate blood sugar levels by enhancing the body's natural ability to control glucose. By inhibiting the DPP-4 enzyme, it increases the levels of incretin hormones, such as GLP-1 and GIP, which stimulate insulin release in response to meals and reduce the production of glucagon. This dual action helps to lower blood glucose levels without causing significant hypoglycemia. Gosogliptin is often prescribed as part of a comprehensive treatment plan that includes diet and exercise. It is particularly beneficial for patients who require an oral medication with a low risk of weight gain or other adverse effects commonly associated with other antidiabetic drugs. Its once-daily dosing regimen also improves patient compliance and convenience.
