Glycolande - General Information:

An antidiabetic sulfonylurea derivative with actions similar to those of chlorpropamide. [PubChem]

Pharmacology:

Glycolande (INN), also known as glyburide (USAN), a second-generation sulfonylurea antidiabetic agent, appears to lower the blood glucose acutely by stimulating the release of insulin from the pancreas, an effect dependent upon functioning beta cells in the pancreatic islets. With chronic administration in Type II diabetic patients, the blood glucose lowering effect persists despite a gradual decline in the insulin secretory response to the drug. Extrapancreatic effects may be involved in the mechanism of action of oral sulfonyl-urea hypoglycemic drugs. The combination of glibenclamide and metformin may have a synergistic effect, since both agents act to improve glucose tolerance by different but complementary mechanisms. In addition to its blood glucose lowering actions, glibenclamide produces a mild diuresis by enhancement of renal free water clearance. Glycolande is twice as potent as the related second-generation agent glipizide.

Glycolande for patients

Patients should be informed of the potential risks and advantages of MICRONASE and of alternative modes of therapy. They also should be informed about the importance of adherence to dietary instructions, of a regular exercise program, and of regular testing of urine and/or blood glucose.

The risks of hypoglycemia, its symptoms and treatment, and conditions that predispose to its development should be explained to patients and responsible family members. Primary and secondary failure also should be explained.

Glycolande Interactions

The hypoglycemic action of sulfonylureas may be potentiated by certain drugs including nonsteroidal anti-inflammatory agents and other drugs that are highly protein bound, salicylates, sulfonamides, chloramphenicol, probenecid, coumarins, monoamine oxidase inhibitors, and beta adrenergic blocking agents. When such drugs are administered to a patient receiving MICRONASE, the patient should be observed closely for hypoglycemia. When such drugs are withdrawn from a patient receiving MICRONASE, the patient should be observed closely for loss of control.

Certain drugs tend to produce hyperglycemia and may lead to loss of control. These drugs include the thiazides and other diuretics, corticosteroids, phe-nothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimet-ics, calcium channel blocking drugs, and isoniazid. When such drugs are administered to a patient receiving MICRONASE, the patient should be closely observed for loss of control. When such drugs are withdrawn from a patient receiving MICRONASE, the patient should be observed closely for hypoglycemia.

A possible interaction between glyburide and ciprofloxacin, a fluoroquinolone antibiotic, has been reported, resulting in a potentiation of the hypoglycemic action of glyburide. The mechanism for this interaction is not known.

A potential interaction between oral miconazole and oral hypoglycemic agents leading to severe hypoglycemia has been reported. Whether this interaction also occurs with the intravenous, topical or vaginal preparations of miconazole is not known. Metformin: In a single-dose interaction study in NIDDM subjects, decreases in glyburide AUC and Cmax were observed, but were highly variable. The single-dose nature of this study and the lack of correlation between glyburide blood levels and pharmaco-dynamic effects, makes the clinical significance of this interaction uncertain. Coadministration of gly-buride and metformin did not result in any changes in either metformin pharmacokinetics or pharmaco-dynamics.

Glycolande Contraindications

MICRONASE Tablets are contraindicated in patients with:

1.Known hypersensitivity or allergy to the drug.

2.Diabetic ketoacidosis, with or without coma. This condition should be treated with insulin.

3.Type I diabetes mellitus, as sole therapy.
