Glucoless is a combination of two active materials:

Metformin is a biguanide antidiabetic agent, lowering basal and postprandial plasma glucose. It reduce

hepatic glucose production and increasing insulin sensitivity in muscle, improving peripheral glucose

uptake also slowing intestinal glucose absorption.

Glibenclamide is one of the second generation sulfonylureas cause a rapid reduction of blood sugar

levels by stimulating release of insulin from the pancreas and increasing isulin binding receptor density

in periphral tissues.

After oral administration of Glucoless Metformin hydrochloride reach the maximum concentration

approximately after 2.5 hours and glibenclamide after 4 hours. Metformin plasma protein binding is

negligible while Glibenclamide is extensively bound to plasma albumin (99%). Metformin is excreted

unchanged by the urine with elimination half-life approximately is 6.5 hours while Glibenclamide is

completely metabolised in the liver into 2 metabolites and excreted in the bile (60%) and urine (40%)

with elimination half-life is 4 to 11 hours.


Treatment of type 2 diabetes ( insulin indenpendent ) in adults, as replacement for previous combination

therapy of metformin and glibenclamide in patients whose glycaemia is stable and well-controlled.


- Initial dose should not exceed the daily dose of metformin and glibenclaminde that already being taken.

- The daily dose prefere to be adjust every two weeks or more according to blood glucose test by not

more than one tablet of Glucoless 5mg /500mg.

- Maximam daily dose is 2000 mg of metformine and 20 mg of glibenclaminde.

- Elderly patient the initial dose is one tablet of Glucoless 2.5mg / 500mg than the dose should be adjust

depend on renal function test.



- Hypersensitivity to metformin, glibenclamide, or other sulfonylureas and sulfonamides.

- Type 1 diabetes (insulin dependent diabetes), ketoacidosis, diabetic pre-coma

- Renal failure or renal dysfunction (serum creatinine > 135μmol / l in men and >110μmol/L in women).

- Dehydration, severe infection, shock, intravenous administration of iodinated contrast agents,

cardio-respiratory failure or myocardial infarction.

- Hepatic insufficiency.

- Children and patients with porphyria.


- The treatment of Glucoless 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.

- During treatment signs of sudden hypoglycemia may occure like cold sweat cold and pale skin,

dizziness, headache, repaid heartbeat feeling sick, starving and nervous in this case treatment should be

stopped and glucose or any food contain suger or honey should be taken in immediatly and tell the

doctor directly.

- Taken Glucoless should be stopped before 48 hours before major surgey or X-ray examination

invalving injection of an iodinal contrast medicine then return to treatment after 48 hours of finishing

after insurring of kidney function.

- Before starting using Glucoless renal function test should be established and during treatment renal

funtion test should should be done periodic.

Use during Pregnancy and Lactation

Pregnant, planning to get pregnant or breast-feeding women should not take this medicine because it

may harm the baby.

Effects on ability to drive and use machines

Glibenclaminde cause hypoglycemia so, should not be taken during drive or use machine.


Glucoless should not be used synchronized with : Miconazole, Phenylbutazone, With all antidiabetic

drugs, Danazol, Chlorpromazine, Corticosteroids (glucocorticoids and tetracosactides) NSAID,

Diuretics, Beta-blockers, Salbutamol, Fluconazole, Angiotensin Converting Enzyme inhibitors

(captopril, enalapril), Clarithromycin, Erythromycin, and Terbutaline.


Metformin :

- The common adverse effects : nausea, vomiting, diarrhea, abdominal pain, loss of appetite and

Metallic taste in the mouth.

- The rare adverse effects : Lactic acidosis, pruritus, urticaria, hepatitis or liver function test

abnormalities resolving upon metformin discontinuation and decrease vit. B12 absorption and serum

level during long-term.

Glibenclamide :

Hypoglycemia, temporary vision disturbances, nausea, vomiting, diarrhea, stomach discomfort, hives,

itching, skin rash possibly leading to symptoms such as breathlessness and even shock, allergic

vasculitis, abnormal laboratory values for liver and kidney tests and blood cells, jaundice, hepatitis,

porphyria, feeling hot and redness.


Metformin : A large overdose may lead to lactic acidosis . Which considered as a serious and

emergency case should be treated in the hospital. The most effective treatment is to remove lactate and

metformin by hemodialysis.

Glibenclamide : may lead to severe life threatening hypoglycemia, the patient must immediately take

sugar. In case of unconsciousness , an intravenous injection of concentrated glucose solution is

indicated ( for adults starting with 40 ml of 20% solution ).


Store below 30OC, in a dry place.
