Drug Overview
Januvia (sitagliptin; Merck & Co) is a member of the dipeptidyl peptidase-IV (DPP-IV) inhibitor class. DPP-IV is an enzyme responsible for the rapid degradation of the incretin hormone glucagon-like peptide-1 (GLP-1), which is released postprandially from the gut. Inhibition of DPP-IV augments the amount of active GLP-1, which in turn triggers increased insulin secretion from the pancreas in a glucose-dependent manner and suppresses the release of glucagon, resulting in lowered blood glucose levels.
The franchise product Janumet/XR ([sitagliptin + metformin/XR]; Merck & Co) addresses the fact that Januvia is generally used as a second- or third-line treatment option as an add-on to metformin.
