Diabetic patients can be treated with glucose-lowering drugs such as insulinotropic agents, biguanides and α-glucosidase inhibitors under the guidance of doctors. 1. Insulin secretagogues: including gliclazide, glipizide, repaglinide, etc. These drugs can act on pancreatic B-cells and promote the secretion of insulin by pancreatic B-cells. 2. Metformin: mainly including metformin, can inhibit the output of hepatic glucose, improve the sensitivity of peripheral tissues to insulin, increase the uptake and utilization of glucose, and then play a role in lowering blood glucose. 3. α-glucosidase inhibitors: these drugs mainly include acarbose, voglibose, etc., which can inhibit α-glucosidase, slow down the absorption of carbohydrates, and then play a role in lowering postprandial blood glucose. Diabetic patients who need to use hypoglycemic drug treatment should be under the guidance of a doctor.
