Trajenta is a brand name for a medication called linagliptin. It is an oral medication used to treat type 2 diabetes. Linagliptin belongs to a class of drugs known as dipeptidyl peptidase/4 (DPP/4) inhibitors. Type 2 diabetes is a chronic condition where the body's cells become resistant to the effects of insulin, leading to elevated blood sugar levels. DPP/4 inhibitors like Trajenta work by increasing the levels of incretin hormones in the body. Incretins help regulate blood sugar levels by increasing insulin secretion from the pancreas in response to meals and by reducing the amount of glucose produced by the liver.Trajenta (linagliptin) is taken orally as a tablet, usually once daily. It is often prescribed as part of a comprehensive treatment plan that may include dietary changes, exercise, and other medications to manage blood sugar levels in people with type 2 diabetes.
