Short-acting hypoglycemic drugs commonly include short-acting insulin, α-glucosidase inhibitors, and glinides. 1. Short-acting insulin: such as Mentholatum insulin, injected before meal, with fast onset of action and short duration of action, it can rapidly reduce postprandial blood glucose. 2. α-glucosidase inhibitors: such as acarbose, voglibose and miglitol, which reduce postprandial blood glucose by delaying glucose absorption, and are taken with meals. 3. Glargine analogs: such as Repaglinide, a non-sulfonylurea insulinotropic agent, promotes insulin secretion after meals and reduces postprandial blood glucose. It is recommended that patients use short-acting hypoglycemic agents under the guidance of a doctor and should not use them on their own.
