Clinically used drugs for lowering postprandial glucose include α-glucosidase inhibitors (such as acarbose), glargine analogs (such as Repaglinide), and short-acting insulin, etc. There is no such thing as the drug of choice, and the treatment should be in accordance with the doctor’s prescription. 1. α-glucosidase inhibitors: such as acarbose, voglibose and miglitol, which can inhibit α-glucosidase located in the small intestine, slowing down the intestinal digestion and absorption of carbohydrates and lowering postprandial blood glucose, the drug is taken with meals. 2. Glargine-type drugs: this kind of drugs mainly includes Repaglinide, Naglinide and Miglinide, which can stimulate the early phase secretion of insulin after meal, and the drugs have fast effect and need to be taken immediately before meal. 3. Short-acting insulin: such as Mentholatum insulin, which has a faster onset of action and a shorter duration of efficacy, is suitable for lowering postprandial blood glucose. It is recommended that patients who have the need to lower postprandial blood glucose should follow the doctor’s instructions to use the drug, and should not use the drug on their own.
