Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that provides a source of glucose, which is metabolized to produce adenosine triphosphate (ATP) via glycolysis and the Krebs cycle. It serves as a carbohydrate caloric agent to prevent or treat hypoglycemia and provide parenteral nutrition.
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. Typical adult dose: 500-1000 mL as a continuous infusion at a rate of 100-200 mL/hour. Dose based on fluid and glucose requirements, typically providing 50-100 g glucose per day.
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.

The terminal elimination half-life of glucose is approximately 1.5–2.5 hours in healthy individuals. In renal impairment, half-life may be prolonged due to reduced gluconeogenesis and altered clearance.
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.
Excreted primarily via renal filtration; <1% is excreted unchanged in urine. The majority is metabolized to CO2 and water via glycolysis and the Krebs cycle, with CO2 eliminated via the lungs.
Renal: 100% (D-glucose and its metabolites, including CO2 and water); less than 1% excreted unchanged in urine under normal conditions; fecal excretion negligible.
