Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose (D-glucose) is a monosaccharide that serves as a substrate for cellular energy production. It is metabolized via glycolysis and the citric acid cycle to produce ATP, and it also participates in the pentose phosphate pathway for NADPH and ribose synthesis.
Dextrose is a carbohydrate that provides caloric support and prevents ketosis. Potassium chloride provides potassium ions for electrolyte balance and cellular function.
Intravenous administration; dose depends on patient's metabolic needs and clinical condition. Typical adult dose: 500 mL of 30% dextrose (150 g dextrose) infused over 4-6 hours, rate not exceeding 0.5 g/kg/hour. Frequency: as needed per blood glucose monitoring.
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.

Not applicable; dextrose is a physiologic sugar with rapid metabolism. In diabetics, impaired utilization may prolong glucose elevation (clinical context: risk of hyperglycemia).
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.
Dextrose is completely metabolized to carbon dioxide and water; <5% excreted unchanged in urine (renal) and none via biliary/fecal routes.
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.
