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 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. 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 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.

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