Introduction

If dietary adjustments are actively made and antidiabetic medications are strictly taken as prescribed, and if pancreatic islet function is relatively good, blood glucose can generally be controlled through mechanisms such as promoting insulin secretion or delaying carbohydrate absorption in the intestines. However, if diet is not actively adjusted and pancreatic islet function is poor, other complications may easily develop, and simply using antidiabetic drugs alone usually cannot maintain blood glucose within the normal range.

Under normal circumstances, if blood glucose-lowering medications are taken as prescribed and combined with proper dietary adjustments and relatively good pancreatic function, blood sugar levels can usually be controlled. Otherwise, glycemic control may not be achieved, and additional drug therapies may be required. The specific analysis is as follows:

1. Possible

If dietary habits are actively adjusted and antidiabetic medications are strictly taken as directed by a physician, and if pancreatic function remains relatively good, these medications generally help lower and control blood glucose by promoting insulin secretion, delaying carbohydrate absorption in the intestines, or enhancing insulin sensitivity. Commonly used drugs include glipizide tablets, gliclazide tablets, and glyburide tablets.

2. Not possible

If, during treatment with oral hypoglycemic agents, dietary adjustments are not made and total daily caloric intake is not controlled, especially when pancreatic function is significantly impaired, other complications may easily develop. In such cases, using oral降糖 drugs alone typically cannot bring blood glucose levels into the normal range, and insulin injections are usually needed to achieve adequate control.

After a diagnosis of diabetes, patients are advised to promptly visit the endocrinology department at a hospital and, under the guidance of a qualified physician, select appropriate methods and medications for effective management, thereby preventing adverse impacts on health due to disease progression.

What are the antidiabetic drugs in the AGI class?

AGIs (alpha-glucosidase inhibitors) include acarbose, voglibose, and miglitol. AGIs are a class of antidiabetic drugs that specifically inhibit alpha-glucosidase—an enzyme essential for the digestion and absorption of carbohydrates. Carbohydrates must interact with alpha-glucosidase to be broken down and absorbed in the gastrointestinal tract.

To which class of antidiabetic drugs does acarbose belong?

Acarbose is an alpha-glucosidase inhibitor used for lowering blood glucose. Its main mechanism of action is to inhibit enzyme activity, thereby reducing the breakdown of carbohydrates or starch from polysaccharides into monosaccharides. This delays and reduces glucose absorption in the body, helping to alleviate postprandial hyperglycemia. Clinically, it is commonly used in conjunction with dietary control for the treatment of diabetes.

Is insulin considered an anti-diabetic drug?

Under normal circumstances, insulin is classified as an anti-hyperglycemic agent. Insulin is a medication that inhibits the rise of blood glucose levels; its primary function is to prevent excessive sugar from entering the body through the bloodstream, thereby stopping increases in blood glucose. Insulin reduces blood sugar levels and promotes the movement of glucose, facilitating the transfer of glucose from the bloodstream into cells, thus preventing elevated blood glucose levels.
