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 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.
Dextrose 5% provides a source of calories and water for hydration, and potassium chloride replenishes potassium stores to maintain cellular function and electrolyte balance.
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.
Intravenous infusion; rate and volume determined by fluid, electrolyte, and caloric requirements of the patient. Typical adult dose: 500-1000 mL of D5 0.15% KCl at a rate of 100-200 mL/hour (2 mL/kg/hour maximum in normokalemic patients). Monitor serum potassium and glucose.

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.
Exogenous potassium has a half-life of approximately 8 hours; dextrose has a half-life of minutes (continuous utilization). Context: Potassium half-life is prolonged in renal failure, requiring dose adjustment.
Potassium: 90% renal, 10% fecal. Glucose: completely metabolized; <1% renal.
Potassium is eliminated primarily by the kidneys (90%), with minor fecal loss (10%). Dextrose is metabolized to CO2 and water; excess is excreted renally. In renal impairment, potassium excretion is reduced.
