May 05, 2025

Managing Type 2 diabetes effectively requires a combination of lifestyle changes, regular monitoring, and appropriate medication. One commonly recommended oral antidiabetic medicine is Gliclazide 60 mg, a second-generation sulfonylurea known for its strong glucose-lowering effect, stable action, and comparatively lower risk of hypoglycemia. Trusted across India, it is widely prescribed to help patients achieve long-term glycaemic control.

This detailed article explains everything you need to know about Gliclazide 60 mg, including how it works, benefits, mechanism of action, safety, dosage guidance, comparisons, precautions, and answers to common FAQs.

1. Introduction to Gliclazide 60 mg

Gliclazide 60 mg is an oral medication used in the management of Type 2 Diabetes Mellitus (T2DM). It belongs to the sulfonylurea class, which stimulates the pancreas to release more insulin when needed. Unlike older sulfonylureas, Gliclazide offers better safety, smoother glucose control, and predictable absorption, making it a preferred choice for long-term diabetic therapy.

In India, doctors often prescribe Gliclazide 60 mg as a once-daily modified-release tablet due to its convenience and improved adherence.

2. What Is Gliclazide 60 mg Used For?

Gliclazide 60 mg is primarily used for:

  • Controlling high blood sugar in Type 2 diabetes

  • Reducing the risk of diabetic complications

  • Lowering HbA1c levels

  • Improving overall glycemic stability

  • Enhancing pancreatic beta-cell activity

It is not recommended in Type 1 diabetes, diabetic ketoacidosis, or in individuals with complete insulin deficiency.

3. Mechanism of Action: How Gliclazide Works

Gliclazide works through multiple pathways:

3.1 Stimulates insulin secretion

It activates pancreatic beta cells to release insulin only when glucose levels are high, which reduces the chance of sudden hypoglycemia.

3.2 Improves insulin sensitivity

It enhances peripheral glucose uptake, helping the body use insulin more efficiently.

3.3 Provides sustained glucose control

The modified-release (MR) form maintains stable blood sugar throughout the day.

3.4 Prevents microvascular complications

Gliclazide is proven to protect blood vessels in the eyes, kidneys, and nerves.

4. Key Benefits of Gliclazide 60 mg

Gliclazide 60 mg offers several clinically proven benefits:
