What Is Trajenta?

What Is Trajenta?

Trajenta is a prescription oral medication that contains linagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor. It is used to help control blood sugar in adults with type 2 diabetes mellitus, when taken along with diet and exercise. Trajenta works by regulating incretin hormones in the body, which helps improve insulin release and reduce glucose production by the liver.

Trajenta is not insulin and should not be used to treat diabetic ketoacidosis or type 1 diabetes. It is available only by prescription from a licensed healthcare provider.

Trajenta is the international brand name for linagliptin and is marketed outside the United States. In the United States, linagliptin is approved by the FDA under the brand name Tradjenta. While both contain the same active ingredient and work in the same way, Trajenta itself is not an FDA-approved U.S. brand name.

What Is the Mechanism of Action of Trajenta?

What Is the Mechanism of Action of Trajenta?

Trajenta (linagliptin) works by inhibiting the enzyme dipeptidyl peptidase-4 (DPP-4). By blocking DPP-4, Trajenta:

  • Increases levels of incretin hormones (GLP-1 and GIP)
  • Enhances glucose-dependent insulin release from the pancreas
  • Reduces glucagon secretion, which lowers glucose production by the liver

Together, these effects help improve blood sugar control in adults with Type 2 diabetes.
