Smegliptide is an insulin sensitizer and belongs to insulin-like peptide-1(GLP- 1) receptor agonist. It can stimulate the secretion of insulin and reduce the secretion of glucagon, thus achieving the effect of lowering blood sugar. Clinically, smectite is often used in patients with type 2 diabetes, especially those who still can't achieve ideal blood sugar control after diet control, exercise and other drug treatments.
