Linagliptin, sold under the brand name Tradjenta among others, is a medication used to treat diabetes mellitus type 2.[3] It is generally less preferred than metformin and sulfonylureas as an initial treatment.[3][4] It is used together with exercise and diet.[3] It is not recommended in type 1 diabetes.[3] It is taken by mouth.[3]

Common side effects include inflammation of the nose and throat.[3] Serious side effects may include angioedema, pancreatitis, joint pain.[4][3] Use in pregnancy and breastfeeding is not recommended.[4] Linagliptin is a dipeptidyl peptidase-4 inhibitor.[3] It works by increasing the production of insulin and decreasing the production of glucagon by the pancreas.[3]

Linagliptin was approved for medical use in the United States in 2011.[3] A month supply in the United Kingdom costs the NHS about £33 as of 2019.[4] In the United States the wholesale cost of this amount is about 391 USD.[5] In 2017, it was the 200th most commonly prescribed medication in the United States, with more than two million prescriptions.[6][7]

Medical uses

Results in 2010 from a Phase III clinical trial of linagliptin showed that the drug can effectively reduce blood sugar.[8]


The defined daily dose is 5 mg by mouth.[1]

Side effects

Linagliptin may cause severe joint pain.[2][9]

The U.S. Food and Drug Administration (FDA) is warning that the type 2 diabetes medicines like sitagliptin, saxagliptin, linagliptin, and alogliptin may cause joint pain that can be severe and disabling. FDA has added a new Warning and Precaution about this risk to the labels of all medicines in this drug class, called dipeptidyl peptidase-4 (DPP-4) inhibitors.

Trajenta's Prescribing Information[10] states the drug is contraindicated for people with bronchial hyperreactivity. Asthma is a form of bronchial hyperreactivity[11][circular reference].

Mechanism of action

Linagliptin belongs to a class of drugs called DPP-4 inhibitors.


Linagliptin is the INN.[12]
