Introduction

Under normal circumstances, medications such as metformin sustained-release tablets, acarbose tablets, gliclazide sustained-release tablets, glibenclamide tablets, and nateglinide capsules can lower blood glucose levels before bedtime. It is recommended to use these medications under a doctor's guidance to ensure their effectiveness and safety. In daily life, it is also important to maintain a balanced diet, engage in appropriate physical activity, and keep a positive mindset to help achieve stable blood glucose control.

Generally, medications such as metformin sustained-release tablets, acarbose tablets, gliclazide sustained-release tablets, glibenclamide tablets, and nateglinide capsules can lower blood sugar levels before bedtime. It is recommended to use these medications under a doctor's guidance to ensure their effectiveness and safety. Detailed explanations are as follows:

1. Metformin Sustained-Release Tablets

These tablets lower blood glucose levels by inhibiting glucose production in the liver and increasing glucose utilization in muscles and fat tissues. They are primarily suitable for patients with type 2 diabetes, especially those who are obese or have hyperinsulinemia.

2. Acarbose Tablets

Acarbose belongs to the class of alpha-glucosidase inhibitors, which delay carbohydrate absorption and thereby reduce postprandial blood glucose levels. It is suitable for diabetic patients whose condition is not adequately controlled by dietary management alone.

3. Gliclazide Sustained-Release Tablets

Gliclazide sustained-release tablets promote insulin secretion from pancreatic beta cells, thus lowering blood glucose levels. They are primarily used to treat mild to moderate type 2 diabetes in patients whose condition is not satisfactorily controlled by diet and physical exercise alone.

4. Glibenclamide Tablets

Glibenclamide tablets stimulate pancreatic beta cells to secrete more insulin, thereby lowering blood glucose levels. They can be used in patients with mild to moderate hyperglycemia when dietary therapy and physical exercise are ineffective.

5. Nateglinide Capsules

Nateglinide capsules are rapid- or short-acting insulin secretagogues that quickly lower postprandial blood glucose levels. They are suitable for diabetic patients whose postprandial blood glucose control is unsatisfactory.

In daily life, attention should also be paid to maintaining a balanced diet, engaging in appropriate physical activity, and keeping a positive mindset to help achieve stable blood glucose control.
