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 carbohydrates and calories to restore blood glucose levels and correct dehydration. Potassium chloride replenishes potassium ions, which are essential for maintaining cellular membrane potential, nerve impulse transmission, and muscle contraction. The combination corrects hypokalemia and prevents potassium depletion during intravenous fluid therapy.
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: 500-1000 mL at a rate of 100-200 mL/hour, not exceeding 25 mEq potassium per hour (or 0.5 mEq/kg/hour) and a maximum concentration of 40 mEq/L. Total daily dose depends on fluid and electrolyte needs.

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.
Dextrose: not applicable (endogenous); potassium: 12-24 hours (distribution half-life), terminal phase not defined due to homeostatic regulation.
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: Potassium excreted primarily via kidneys (90%) with some fecal loss; dextrose is metabolized to CO2 and water, excreted renally as water and bicarbonate (less than 5% unchanged).
