Indications
This tablet is indicated as an adjunct to diet and exercise in type 2 diabetes mellitus patients- In case that the monotherapy with glimepiride or metformin does not result in adequate glycemic control. Replacement of combination therapy of glimepiride and metformin.
Pharmacology
Glimepiride is a sulfonylurea antidiabetic agent which decreases blood glucose concentration. The primary mechanism of action of Glimepiride appears to be dependent on stimulating the release of insulin from functioning pancreatic beta cells. Glimepiride acts in concert with glucose by improving the sensitivity of beta cells to physiological glucose stimulus, resulting in insulin secretion. In addition, extrapancreatic effects like reduction of basal hepatic glucose production, increased peripheral tissue sensitivity to insulin and glucose uptake may also play role in the activity of Glimepiride. In non-fasting diabetic patients, the hypoglycaemic action of a single dose of Glimepiride persists for 24 hours. Metformin Hydrochloride is a biguanide type oral antihyperglycemic drug used in the management of type 2 diabetes. It lowers both basal and postprandial plasma glucose. Its mechanism of action is different from those of sulfonylureas and it does not produce hypoglycemia. Metformin Hydrochloride decreases hepatic glucose production, decreases intestinal absorption of glucose and improves insulin sensitivity by an increase in peripheral glucose uptake and utilization.
Dosage Administration
The dosage of this tablet is governed by the desired blood glucose level. The dosage of this tablet must be the lowest which is sufficient to achieve the desired metabolic control. During treatment with this tablet glucose levels in blood and urine must be measured regularly. Mistakes, e.g. forgetting to take a dose, must never be corrected by subsequently taking a larger dose. As an improvement in control of diabetes is, in itself, associated with higher insulin sensitivity, glimepiride requirements may fall as treatment proceeds. To avoid hypoglycaemia timely dose reduction or cessation of this tablet therapy must therefore be considered. The highest recommended dose per day should be 8 mg of glimepiride and 2000 mg of metformin. In order to avoid hypoglycaemia the starting dose of this tablet should not exceed the daily doses of glimepiride or metformin already being taken. When switching from combination therapy of glimepiride plus metformin as separate tablets, this combination should be administered on the basis of dosage currently being taken.
Side Effects
Pregnancy- For Glimepiride: Glimepiride must not be taken during pregnancy. Otherwise, there is risk of harm to the child. The patient must change over to insulin during pregnancy. Patients planning a pregnancy must inform their physician. It is recommended that such patients change over to insulin. For Metformin: When the patient plans to become pregnant and during pregnancy, diabetes should not be treated with metformin but insulin should be used to maintain blood glucose levels as close to normal as possible in order to lower the risk of fetal malformations associated with abnormal blood glucose levels. Lactation- For Glimepiride: To prevent possible ingestion with the breast milk and possible harm to the child, glimepiride must not be taken by breast-feeding women. If necessary the patient must change over to insulin, or must stop breastfeeding. For Metformin: Metformin is excreted into milk in lactating rats. Similar data is not available in humans and a decision should be made whether to discontinue nursing or to discontinue metformin, taking into account the importance of the compound to the mother.
Pregnancy And Lactation
For Glimepiride- In patients hypersensitive to glimepiride, metformin, other sulfonylureas, other sulfonamides, or any of the excipients of Amaryl M. In pregnant women. In breastfeeding women. No experience has been gained concerning the use of glimepiride in patients with severe impairment of liver function and in dialysis patients. In patients with severe impairment of hepatic function, change-over to insulin is indicated, not least to achieve optimal metabolic control. For Metformin- Hypersensitivity to metformin or any of the excipients. Any type of acute metabolic acidosis such as lactic acidosis Diabetic ketoacidosis, diabetic pre-coma. Severe Renal failure or renal disfunction (e.g., serum creatine levels >135 ?mol/L in males and >110 ?mol/L in females), GFR < 30 mL/min. Acute conditions with the potential to alter renal function such as Dehydration, severe infection, intravascular administration of iodinated contrast agents etc. Acute or chronic disease which may cause tissue hypoxia such as cardiac or respiratory failure, recent myocardial infarction, shock Hepatic insufciency. Acute alcohol intoxication, alcoholism. Lactation.
Therapeutic
For Glimepiride: In the initial weeks of treatment, the risk of hypoglycemia may be increased and necessitates especially careful monitoring. If risk factors for hypoglycemia are present, it may be necessary to adjust the dosage of glimepiride or the entire therapy. This also applies whenever illness occurs during therapy or the patient's life-style changes. It is known from other sulfonylureas that, despite initially successful countermeasures, hypoglycaemia may recur. Patients must, therefore, remain under close observation. Severe hypoglycaemia further requires immediate treatment and follow-up by a physician and, in some circumstances, in-patient hospital care. Treatment of patients with G6PD-defciency with sulfonylurea agents can lead to hemolytic anaemia. Since glimepiride belongs to the class of sulfonylurea agents, caution should be used in patients with G6PD-defciency and a non-sulfonylurea alternative should be considered. For Metformin: Regular monitoring of thyroid-stimulating hormone (TSH) levels is recommended in patients withhypothyroidism. Long-term treatment with metformin has been associated with a decrease in vitamin B12 serumlevels which may cause peripheral neuropathy. Monitoring of the vitamin B12 level is recommended.
Storage Conditions
Children: Data is insufficient to recommend pediatric use of this tablet. Renal impairment: A GFR should be assessed before initiation of treatment with metformin-containing products and at least annually thereafter. In patients at increased risk of further progression of renal impairment and in the elderly, renal function should be assessed more frequently, e.g. every 3-6 months. The maximum daily dose of metformin should preferably be divided into 2-3 daily doses. Factors that may increase the risk of lactic acidosis should be reviewed before considering the initiation of metformin in patients with GFR<60 mL/min. If no adequate strength of this tablet is available, individual monocomponents should be used instead of the fixed dose combination. GFR 60-89 ml/min: Metformin: Maximum daily dose is 3000 mg. Dose reduction may be considered in relation to declining renal function. Glimepiride: The highest recommended dose per day should be 8 mg of glimepiride. GFR 45-59 ml/min: Metformin: Maximum daily dose is 2000 mg. The starting dose is at most half of the maximum dose. GFR 30-44 ml/min: Metformin: Maximum daily dose is 1000 mg. The starting dose is at most half of the maximum dose. GFR <30 ml/min: Metformin: Metformin is contraindicated Glimepiride: Change-over to insulin is indicated, not least to achieve optimal metabolic control.
