Generic

Glimepiride

 

Indications

Glimepiride is indicated as an adjunct to diet to lower the blood glucose in patients with non-insulindependent diabetes mellitus (type 2 diabetes) whose hyperglycemia cannot be controlled by diet, physical exercise and weight reduction.

Glimepiride is also indicated for use in combination with Insulin to lower blood glucose in patients whose hyperglycaemia can not be controlled by diet and exercise or in conjunction with an oral hypoglycaemic agent.

 

Pharmacology

Glimepiride stimulates the insulin release from pancreatic β-cells and reduces glucose output from the liver. It also increases insulin sensitivity at peripheral target sites.

 

Dosage & Administration

In principle, the dosage of Glimepiride is governed by the desired blood sugar level. The dosage of Glimepiride must be the lowest which is sufficient to achieve the desired metabolic control. The initial and the maintenance doses are set based on the results of regular check of glucose in blood and urine. Monitoring of glucose levels in blood and urine also serves to detect either primary or secondary failure of therapy.

Initial dose and dose titration: the usual initial dose is 1 mg once daily, if necessary, the daily dose can be increased. Any increase can be based on regular blood sugar monitoring, and should be gradual, i.e., at intervals of 1 to 2 weeks, and carried out stepwise, as follows: 1 mg -> 2 mg -> 3 mg -> 4 mg -> 6 mg.

Dose in patients with well controlled diabetes: the usual dose range in patients with well controlled diabetes is 1 to 4 mg daily.

Distribution of doses: Timing and distribution of doses are decided by the physician, in consideration of the patient's current life-style. Normally, a single daily dose is sufficient. This should be taken immediately before a substantial breakfast or if none is taken immediately before the first main meal. It is very important not to skip meals after taking the drug.

Secondary dosage adjustment: As control of diabetes improves, sensitivity to insuiin increases; therefore, Glimepiride requirement may fall as treatment proceeds. To avoid hypoglycaemia, timely dose reduction or cessation of Glimepiride therapy must be considered. A dose adjustment must also be considered whenever the patient's weight or life-styie changes, or other factors arise which cause an increased susceptibility to hypo or hyperglycaemia.

Changeover from other oral antidiabetics to Glimepiride: There is no exact dosage relationship between Glimepiride and other oral blood sugar lowering agents. When substituting Glimepiride for other such agents, the initial daily dose is 1 mg; this applies even in changeover from maximum dose of other oral blood sugar lowering agents. Any dose increase should be in accordance with guideline given above in 'initial dose and dose titration'. Consideration must be given to the potency and duration of action of the previous blood sugar lowering agent. It may be necessary to interrupt treatment to avoid additive effects which would increase the risk of hypoglycaemia.

 

Interactions

Potentiation of the blood-sugar-lowering effect may occur with Insulin and other oral anti-diabetics, ACE inhibitors, Allopurinol, anabolic steroids and male sex hormones, Chloramphenicol, coumarin derivatives, Fluoxetine, MAO inhibitors, Miconazole, Para-aminosalicyclic acid, Pentoxifylline (high dose parenteral), Phenylbutazone, Oxyphenbutazone, quinolones, salicylates, sulphonamides, tetracyclines, β blockers.

Weakening of the blood-sugar-lowering effect may occur with Acetazolamide, barbiturates, corticosteroids, Diazoxide, diuretics, Epinephrine and other sympathomimetic agents, laxative, oestrogens and progestogens, phenothiazines, Phenytoin, Rifampicin, and thyroid hormones. H2 -receptor antagonists, Clonidine and Reserpine may lead to either potentiation or weakening of the blood-sugar-lowering effect. Both acute and chronic alcohol intake may potentiate or weaken the blood-sugar-lowering action of Glimepiride unpredictably.

 

Contraindications

Glimepiride is not suitable for the treatment of insulin dependent (type I) diabetes mellitus, or for the treatment of diabetic ketoacidosis, nor for the treatment of diabetic coma. Glimepiride must not be used in patients hypersensitive to Glimepiride, other sulfonylureas

 

Side-Effects

Hypoglycaemia, temporary visual impairment, nausea, vomiting, diarrhoea, abdominal pain, urticaria, fall in blood pressure.

 

Pregnancy

Glimepiride must not be taken during pregnancy; a changeover to insulin is necessary. Patients planning a pregnancy must inform their physician, and should change over to insulin. Ingestion of Glimepiride with breast milk feeding may harm the child. Therefore, Glimepiride must not be taken by breastfeeding women. Either a changeover or complete discontinuation of breastfeeding is necessary

 

Precautions

In the initial weeks of treatment, the risk of hypoglycaemia may be increased and necessitates careful monitoring. If such risk present it may be necessary to adjust the dosage of Glimepiride, Hypoglycaemia can almost be promptly controlled by immediate intake of carbohydrates (glucose or sugar).
