Gliclazide is an oral anti-diabetic medication containing Gliclazide (60mg) in a modified-release (MR) formulation. It belongs to the sulfonylurea class and is used to control blood sugar levels in adults with Type 2 Diabetes Mellitus (T2DM). Stimulating the pancreas to produce more insulin at the correct times helps keep blood glucose within a healthy range, especially when lifestyle changes alone are insufficient.

Gliclazide is a sophisticated, modified-release oral pharmacological therapy specifically developed for the long-term clinical management of Type 2 Diabetes Mellitus. The core active pharmaceutical ingredient is Gliclazide, a potent second-generation sulfonylurea that has been precision-engineered to target the insulin-secreting beta cells within the pancreas.

Unlike traditional immediate-release formulations that require multiple doses throughout the day, this 60mg modified-release tablet utilises an advanced delivery matrix. This technology ensures the medication is released into the systemic circulation at a steady, controlled rate over a full 24-hour period. This gradual release profile is significant because it facilitates stable, around-the-clock glycemic control with the convenience of a single daily dose, greatly improving patient adherence to treatment regimens.

The primary physiological function of Gliclazide involves restoring the crucial first peak of insulin secretion, a metabolic response to glucose that is typically diminished or entirely lost in individuals living with Type 2 Diabetes. Once ingested, the medication binds with high affinity to specific sulfonylurea receptors located on the surface of the pancreatic beta cells. This binding process triggers a sequence of intracellular events that stimulate the release of endogenous insulin, particularly in direct response to food intake.

In addition to its primary glucose-lowering capabilities, Gliclazide is scientifically recognised for its unique "hemovascular" properties. These secondary benefits involve a reduction in the microthrombotic processes, essentially helping to inhibit the formation of tiny blood clots and preventing the "stickiness" of platelets. By addressing these vascular factors, the medication plays a dual role: managing blood sugar while simultaneously mitigating the underlying processes that lead to diabetic complications.

By smoothing out these glycemic fluctuations, Gliclazide serves as an exceptionally effective tool for the sustained lowering of HbA1c levels.

Ultimately, the goal of maintaining such steady glycemic levels is the prevention of chronic microvascular and macrovascular damage. Consistent use of this medication, as part of a comprehensive care plan, is intended to significantly reduce the risk of long-term debilitating damage to the:

• Cardiovascular system (heart and blood vessels)
• Renal system (kidneys)
• Visual health (retina and eyes)
• Peripheral nervous system (nerves)

Gliclazide (Gliclazide 60mg) is indicated for:

Type 2 Diabetes Mellitus (T2DM):

For the control of high blood sugar in adults when dietary measures, physical exercise, and weight loss alone are not adequate.

Combination Therapy:

Can be used alongside other anti-diabetic agents like Metformin, alpha-glucosidase inhibitors, or insulin when blood sugar goals are not met with a single drug.

• 24-Hour Control: The modified-release technology ensures steady blood sugar regulation throughout the day and night.
• Restores Natural Response: Helps the body regain its early insulin response to food intake.
• Cardiovascular Safety: Widely regarded for its long-term safety profile regarding heart health compared to some older sulfonylureas.
• Reduced Complications: Effectively lowers the risk of microvascular complications like diabetic retinopathy (eye damage) and nephropathy (kidney damage).
• Simple Regimen: Once-daily dosing with breakfast improves patient compliance.

Most side effects are mild and can be managed with proper meal timing.

Common Side Effects:

• Hypoglycemia: Low blood sugar (feeling hungry, shaking, sweating, or confused).
• Digestive Upset: Stomach pain, nausea, or indigestion.

Serious Side Effects (Seek urgent medical attention):

• Liver Disorders: Yellowing of the skin/eyes, dark urine, and fatigue.
• Severe Skin Reactions: Rash, redness, or blistering (Stevens-Johnson Syndrome).
• Blood Count Changes: Unusual bruising, sore throat, or fever (which may indicate a drop in white or red blood cells).

• Dosage: Usually starts at 30mg or 60mg once daily, adjusted by your doctor up to a maximum of 120mg.
• Administration: Take the tablet whole with breakfast. Do not crush or chew it, as this destroys the modified-release mechanism.
• Timing: It is crucial to take this medication with a meal to prevent blood sugar from dropping too low.
• Consistency: Take it at the same time every morning to maintain stable levels

Gliclazide acts primarily on the pancreatic beta cells. It binds to the sulfonylurea receptor-1 (SUR1), which closes ATP-sensitive potassium channels. This change in the cell's electrical state opens calcium channels, causing the "burst" release of insulin. Its unique "modified release" allows this process to happen in a controlled manner over 24 hours, mimicking the body's natural needs more closely than older medications.

• Meal Timing is Key: Always eat breakfast after taking your tablet.
• Hypo Treatment: Keep a "hypo kit" (glucose tabs or a sugary drink) in your car and bag at all times.
• Don't Crush: Remember that these are modified-release tablets; breaking them can lead to too much medicine entering your system at once.
• Foot Care: Regular foot checks are vital for anyone on diabetes medication.

Store in a cool, dry place below 30°C. Keep the tablets in their original blister pack to protect them from moisture. Keep out of reach of children.
