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 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 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: 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.

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.
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: 90% renal, 10% fecal. Glucose: completely metabolized; <1% renal.
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.
