Teneligliptin is primarily used in the management of type 2 diabetes mellitus. It functions as a dipeptidyl peptidase-4 (DPP-4) inhibitor, which helps in regulating blood sugar levels by increasing the release of insulin and decreasing the production of glucose by the liver. This medication is often prescribed when diet, exercise, and other antidiabetic agents do not provide adequate glycemic control. It is particularly beneficial for patients who require a once-daily oral treatment, offering convenience and improved adherence. Additionally, Teneligliptin has shown efficacy in reducing postprandial glucose levels, making it a valuable option for managing meal-related blood sugar spikes. Its use is generally well-tolerated, with a lower risk of hypoglycemia compared to some other antidiabetic drugs, making it a suitable choice for a broad range of patients.
