GCG and Hypoglycemia: This is a new therapeutic class for treating diabetes, whose mechanism includes stimulating beta cells to increase insulin synthesis and action on pancreatic alpha cells, reducing glucagon production. Glucagon has the effect of increasing glycemic levels. Average potential of A1C reduction (0.5 - 0.8%, depending on the basal A1C value). Do not cause hypoglycemia but gastrointestinal intolerance and pancreatitis have been described (exenatide and sitaglipitn) [13,14].
