Linagliptin, sold under the brand name Tradjenta among others, is a medication used to treat type 2 diabetes (but not type 1) in conjunction with exercise and diet. [7] [8] Linagliptin is a dipeptidyl peptidase-4 inhibitor [7] that works by increasing the production of insulin and decreasing the production of glucagon by the pancreas. [7] It is generally less preferred than metformin and sulfonylureas as an initial treatment. [7] [9] It is taken by mouth. [7]
Common side effects include inflammation of the nose and throat. [7] Serious side effects may include angioedema, pancreatitis, joint pain. [9] [7] Use in pregnancy and breastfeeding is not recommended. [9]
Linagliptin was approved for medical use in the United States, [10] Japan, the European Union, Canada, and Australia in 2011. [7] [11] In 2020, it was the 293rd most commonly prescribed medication in the United States, with more than 1 million prescriptions. [12] [13] From August 2021 linagliptin became available as a generic medicine in the US. [14]
Linagliptin is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes. [5]
Linagliptin belongs to a class of drugs called DPP-4 inhibitors. [5]
Linagliptin is the international nonproprietary name (INN). [16] Brand names: Trajenta, [17] Tradjenta.
