Linagliptin and Metformin tablets are a combination medication used in the treatment of type 2 diabetes mellitus. Linagliptin: Linagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor. It works by increasing the levels of incretin hormones in the body. These hormones help to control blood sugar levels by stimulating the release of insulin after meals and decreasing the amount of sugar made by the body. Metformin: Metformin belongs to the biguanide class of antidiabetic medications. It works by decreasing the amount of glucose produced by the liver and increasing the sensitivity of muscle cells to insulin. This helps to lower blood sugar levels. The combination of Linagliptin and Metformin helps to improve glycemic control in patients with type 2 diabetes by targeting different mechanisms involved in blood sugar regulation.
