Trajenta, also known by its generic name linagliptin, is a prescription medication used to treat type 2 diabetes. It is an oral medication that works by increasing the levels of incretin hormones in the body. Incretin hormones are responsible for stimulating insulin release and decreasing the amount of glucose produced by the liver. By regulating these processes, Trajenta helps control blood sugar levels in patients with type 2 diabetes.

Trajenta works by inhibiting the activity of DPP-4, an enzyme that breaks down incretin hormones. By inhibiting DPP-4, Trajenta allows incretin hormones to remain active in the body for longer periods, leading to increased insulin secretion and reduced glucagon levels. This ultimately helps lower blood sugar levels in individuals with type 2 diabetes.

Trajenta is primarily prescribed for individuals diagnosed with type 2 diabetes. It is typically recommended for patients who have not achieved adequate blood sugar control through lifestyle modifications such as diet and exercise alone. Trajenta is often used as part of a comprehensive treatment plan that may include other oral medications or insulin therapy. However, it is important to consult with a healthcare professional to determine if Trajenta is the right medication for you.
