Glucolow XR ( Metformin ) is a biguanide antidiabetic agent, lowering both basal and postprandial plasma glucose.

Glucolow XR does not stimulate insulin secretion and therefore does not produce hypoglycaemia ,it acts by reduction

of hepatic glucose production ,increasing insulin sensitivity in muscles ,hence improving peripheral tissue for glucose

uptake and delay intestinal glucose absorption. After an oral dose of Glucolow XR tablet the absorption does not

effected by meals, the maximum plasma concentration is reached in approximately 7 hours. Plasma protein binding is

negligible. It is excreted unchanged in the urine with elimination half-life is approximately 6.5 hours.


Glucolow XR is used for treatment of type 2 diabetes mellitus (Insulin independent), particularly in overweight

patients, when dietary management and exercise alone does not result in adequate glycaemic control.

In adults: Metformin can be used as monotherapy, in combination with insulin or with other oral antidiabetic agents.


• Adults : The usual starting dose is one tablet of Glucolow XR 500 at evening meal once daily. After 10 - 15 days the

maximum recommended dose is 4 tablets of Glucolow XR 500 daily.

• Glucolow XR 750 and Glucolow XR 1000 are intended for patients who are already treated with metformin tablets

(prolonged or immediate release). And the dose of them should be equivalent to the daily dose of metformin tablets

• Elderly patients : The dose should be adjusted on the based on renal function test.

• Combination with insulin : given at the usual starting dose (one tablet of Glucolow XR 500 once daily ) while

- Hypersensitivity to Metformin.

- Diabetic ketoacidosis (symptoms include abdominal pain, fast and deep breathing, sleepiness or unusual mouth odor)

and diabetic pre-coma.

- Renal failure or renal dysfunction (creatinine clearance rate less than 60 ml/min), hepatic insufficiency , excessive

consumption of alcohol.

- Cases that accompanied by renal function change such as dehydration, severe infection such as respiratory or urinary

tract infections and shock.

- Diseases which cause hypoxia in tissues such as cardiac respiratory failure, recent myocardial infarction or shock.


- The treatment of Metformin should be stopped immediately and consult the doctor ,if lactic acidosis symptoms

appear which include vomiting, abdominal pain with muscle cramps ,fatigue and difficulty in breathing, this case

occurs due to Metformin accumulation especially in patients with renal impairment.

- The treatment of Metformin should be stopped , in case of X- ray examination by injection of iodinated contrast

media ( Iodinated Radiographic dye use to show the organs and vessels in X-ray photo) and the treatment should not

be resumed until 48 hours after the test , after ensuring that kidney function is normal.

- Regular tests should be done to monitor blood glucose level and kidney function before initiation and during

treatment with Metformin. Metformin is excreted by kidneys, caution should be taken when start taking

antihypertensive drugs, diuretic or NSAIDs due to the probability of alteration of renal function.

- In case of undergoing a major surgery ,the treatment of Metformin should be stopped 48 hours before the surgery

and 48 hours after the surgery , the treatment should not be resumed unless after ensuring that kidney function is


- The patient should inform the doctor of taking any other drug or any infection.

diabetes and they should consult the doctor for replacement of Glucolow XR by Insulin . Glucolow XR is not

recommended during breast-feeding.

Effects on ability to drive vehicles and use machines

Metformin monotherapy does not cause hypoglycaemia and therefore has no effect on the ability to drive or use

machines, hypoglycaemia may occur when metformin is used in the same time with other antidiabetic agents, hence

the mental concentration may be confused.


Caution should be taken when co-administration of Metformin with corticosteroids, NSAIDs ,antihypertensive agents

of ACEI class , diuretics, Beta 2 agonists such as salbutamol, alcohol containing medicaments.


The most common : Nausea, vomiting, diarrhea, abdominal pain and loss of appetite may occur especially at the

beginning of treatment .

Common effects : Taste disturbances.

Very rare : Lactic acidosis , itching , red skin , decrease in vitamin B12 level in blood.
