Description: Teneligliptin belongs to the DPP-IV inhibitor class of medications. These medicines inhibit the action of the enzyme DPP-IV, which breaks down incretins (hormones released after eating). Incretins stimulate insulin production and help the body use glucose for fuel. By inhibiting DPP-IV, teneligliptin helps increase the amount of active incretin hormones in the bloodstream. Metformin lowers blood sugar levels by reducing the amount of glucose produced by the liver. Metformin reduces the amount of glucose produced by the liver by inhibiting gluconeogenesis. Inhibition of gluconeogenesis means that fewer nutrients are converted into glucose, therefore reducing the amount of glucose in the blood.
