Evogliptin tartrate is primarily used in the treatment of type 2 diabetes mellitus. It functions as a dipeptidyl peptidase-4 (DPP-4) inhibitor, which helps regulate blood sugar levels by increasing the release of insulin and decreasing the production of glucagon. This makes it effective in managing hyperglycemia in diabetic patients. It is often prescribed as part of a comprehensive treatment plan that includes diet and exercise. The medication is particularly beneficial for patients who require better glycemic control without significant risk of hypoglycemia. It is typically administered orally, making it convenient for long-term use.
