Usage


Linagliptin is an inhibitor of dipeptidyl peptidase 4 (DPP-4), which degrades incretin-like polypeptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). Linagliptin increases the concentration of active incretin hormones, stimulates insulin release in a glucose-dependent manner, and reduces circulating glucagon levels.


Linagliptin in combination with metformin and sulfonylureas, with diet and exercise, can be used for glycemic control in adults with type II diabetes.
