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 is a monosaccharide that serves as a substrate for cellular energy production via glycolysis and the citric acid cycle. It increases blood glucose levels, providing an immediate source of calories and carbohydrate for patients with hypoglycemia or caloric needs.
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.
Adults: 50 mL (20 g dextrose) intravenously as a single dose for hypoglycemia; may repeat if needed. For hyperkalemia with insulin: 25 g (62.5 mL) IV with 10 units regular insulin.

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.
30-60 minutes; clinical context: rapid redistribution and metabolism limit hyperglycemic effect, but in glucose-6-phosphatase deficiency or hepatic impairment, half-life may extend to 2-4 hours.
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.
Dextrose is completely metabolized to carbon dioxide and water; less than 5% is excreted unchanged in urine. Renal excretion accounts for <5% of elimination; biliary/fecal elimination is negligible.
