Used in the management of type 2 diabetes mellitus as a once-daily oral antihyperglycemic agent. It functions by enhancing the activity of incretin hormones, which stimulate insulin release in a glucose-dependent manner, thereby lowering blood glucose levels without increasing the risk of hypoglycemia. Often prescribed as monotherapy or in combination with other antidiabetic medications such as metformin or pioglitazone. Its long half-life allows for convenient daily dosing, improving patient adherence. Suitable for patients requiring improved glycemic control with a low risk of weight gain or hypoglycemic episodes.
