Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Dextrose is a monosaccharide that serves as a source of calories and water for hydration. It is metabolized to carbon dioxide and water, yielding energy. Potassium chloride dissociates to provide potassium ions, which are essential for maintenance of intracellular tonicity, nerve impulse transmission, contraction of cardiac, skeletal, and smooth muscle, and maintenance of normal renal function.
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.
Intravenous infusion; rate and volume determined by patient fluid and electrolyte status. Typical maintenance: 100-125 mL/hour for adults, providing 5 g dextrose and 7.5 mEq potassium chloride per liter.

Dextrose: not applicable (endogenous); potassium: 12-24 hours (distribution half-life), terminal phase not defined due to homeostatic regulation.
Potassium: terminal half-life ~1-1.5 hours in normokalemic patients; clinically relevant for dosing interval. Glucose: negligible terminal half-life due to rapid metabolism.
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).
Potassium: 90% renal, 10% fecal. Glucose: completely metabolized; <1% renal.
