Mechanism of action: incretins, sush as glucagon-like peptide-1 (GLP-1), it is enhance glucose-dependent insulin secreation and exhibit other antihyperglycemic actions following their release into the circulation from the gut. BYETTA (exenatide injection) is a GLP-1 receptor agonist that enhances glucose-dependent insulin secreation, and slows gastric emptying.
Adverse reaction: hypoglycemia
Sitagliptin (Januvia)
Mechanism of action: it is a DPP-4 inhibitor, which is believed to exert its actions in patients with type 2 diabetes by slowing the inactivation of incretin hormones. Concentrations of the active intact hormones are increased by JANUVIA, therapy increasing and prolonging the action of these hormones. Incretin
