Mechanism of Action

Gliclazide stimulates insulin secretion from pancreatic β-cells, reduces hepatic gluconeogenesis, and lowers blood glucose concentrations. It also inhibits platelet aggregation at therapeutic doses. Duration: ≥12 hr. Absorption: Readily absorbed from the GI tract (oral). Distribution: Protein-binding: 94%. Metabolism: Extensively hepatic; converted to inactive metabolites. Excretion: Urine (60-70% metabolites and small amounts of unchanged drug); faeces (10-20%); 10-12 hr (elimination half-life).

Special Precautions

Monitor blood glucose concentration. May require insulin during metabolic stress. Care when transferring from combination therapy. Increased risk of severe hypoglycaemia in elderly, debilitated patients, patients with hepatic or renal impairment. Risk of hypogylcaemia when caloric intake is deficient, after strenuous exercise, when taken with ethanol or when >1 antidiabetic drug is used.
