text: [Glucagon-like peptide 1 (GLP-1)].
  GLP-1 receptor agonists such as exenatide are a group of new therapeutic agents that mimic the gut-derived incretin hormone GLP-1. These drugs stimulate insulin secretion while suppressing glucagon secretion, inhibit gastric motility, reduce appetite and hence, food intake. This group of drugs also induce reduction in fasting and postprandial glucose concentrations, HbA1c and ultimately lead to weight loss. The drugs are administered subcutaneously (exenatide twice daily). The most common side effect is mild nausea. Although short-term studies are promising, long-term clinical studies are needed to determine the benefits of this approach for the treatment of type 2 diabetes.
