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 carbohydrate that provides caloric support and prevents ketosis. Potassium chloride provides potassium ions for electrolyte balance and cellular 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: 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.

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 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.
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.
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.
