Monitor blood and urine glucose concentrations, glycosylated Hb, renal function, LFT, weight; signs and symptoms of hypoglycaemia.
Symptoms: Hypoglycaemia; faintness, confusion, sweating or shaking. Management: Mild hypoglycaemia may be treated with oral glucose or with any sugary food or drinks. For severe hypoglycaemia, administer glucagon or rapid IV inj of glucose 50% solution followed by continuous infusion of glucose 10% solution. Monitor patient for at least 48 hours.
Increased plasma concentration with fluconazole and voriconazole. Increased hypoglycaemic effect with NSAIDs (e.g. phenylbutazone), ACE inhibitors, MAOIs, cimetidine, chloramphenicol, probenecid, coumarins and fibrates. Potentially Fatal: Severe hypoglycaemia leading to coma with miconazole.
Increased hypoglycaemic action with alcohol.
Description: Mechanism of Action: Glipizide stimulates insulin release from pancreatic ß-cells and reduces glucose output from the liver. It also increases insulin sensitivity at peripheral target sites. Duration: 12-24 hours. Pharmacokinetics: Absorption: Rapidly and completely absorbed from the gastrointestinal tract (immediate-release). Food delays absorption. Bioavailability: 90-100%. Time to peak plasma concentration: 1-3 hours; 6-12 hours (extended-release). Distribution: Plasma protein binding: 98-99%, primarily to albumin. Volume of distribution: 10-11 L. Metabolism: Metabolised in the liver by CYP2C19 to inactive metabolites. Excretion: Via urine (<10% as unchanged drug; 80% as metabolites); faeces (10%). Elimination half-life: 2-5 hours.
Immediate-release: Store below 25°C. Protect from light. Extended-release: Store between 20-25°C. Protect from moisture and humidity.
