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 calories and water for hydration, and potassium chloride replenishes potassium stores to maintain cellular function and electrolyte balance.
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; 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.

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.
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.
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.
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.
