<p>It controls blood glucose levels by selectively and continually inhibiting DPP-4, an enzyme that causes the inactivation of glucagon-like peptide-1 and glucagon-dependent insulinotropic polypeptide, incretin hormones that play an important role in blood glucose regulation. The inhibition of DPP-4 increases insulin secretion depending on blood glucose concentration, thereby controlling blood glucose levels. It is indicated for the treatment of type 2 diabetes.</p>
