Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose 5% provides a source of calories and water for hydration, and potassium chloride replenishes potassium stores to maintain cellular function and electrolyte balance.
Dextrose is a carbohydrate that provides caloric support and prevents ketosis. Potassium chloride provides potassium ions for electrolyte balance and cellular function.
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.
Intravenous infusion: 5% dextrose and 0.224% potassium chloride at a rate of 100-200 mL/hour for maintenance fluid and electrolyte replacement, adjusted based on serum potassium levels and clinical status.

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: Terminal half-life approximately 4–6 hours in patients with normal renal function, but highly variable depending on glomerular filtration rate; up to 20–30 hours in severe renal impairment. Dextrose: Not applicable as it is rapidly cleared from blood via insulin-mediated uptake; metabolic half-life minutes.
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.
Exclusively renal: >98% of potassium ion is excreted via kidneys, with minimal fecal loss. Dextrose is completely metabolized to CO2 and water, with no direct renal excretion of intact dextrose under normal conditions.
