DEXTROSE 20% IN PLASTIC CONTAINER vs DEXTROSE 5%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that serves as a source of calories and water for parenteral nutrition. It is oxidized to carbon dioxide and water, providing energy. Administration of hypertonic dextrose solutions increases blood glucose levels, which can stimulate insulin secretion and promote cellular glucose uptake.
Dextrose 5% provides a source of calories and water for intravenous administration. It is metabolized to carbon dioxide and water, yielding energy. Dextrose solutions exert osmotic effects and can increase blood glucose levels.
Intravenous infusion; adult dose: 500-1000 mL of 20% dextrose solution (100-200 g dextrose) administered over 1-2 hours; maximum infusion rate: 0.5 g/kg/hour. Frequency: as needed for hypoglycemia or as part of parenteral nutrition.
Intravenous infusion; 5% dextrose in water (D5W) is typically administered at a rate of 100-200 mL/hour to provide 50-100 g of glucose per day for maintenance hydration and minimal caloric support in adults.

Plasma half-life is approximately 2-5 minutes under normal conditions due to rapid cellular uptake and metabolism; prolonged in hyperglycemic states or renal impairment.
0.5-1 hour (endogenous glucose); intravenous infusion half-life is variable due to continuous cellular uptake and metabolism; clinical context: rapid clearance via insulin-mediated cellular uptake and glycolysis.
Dextrose is completely metabolized to carbon dioxide and water via glycolysis and the citric acid cycle; negligible renal excretion of unchanged drug. <1% excreted unchanged in urine.
Renal: 100% (D-glucose and its metabolites, including CO2 and water); less than 1% excreted unchanged in urine under normal conditions; fecal excretion negligible.
