Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides caloric support and restores blood glucose levels, while electrolytes (such as sodium, potassium, magnesium, chloride, acetate, and phosphate) replace deficits and maintain acid-base balance. The specific electrolyte composition in No. 48 (e.g., sodium, potassium, magnesium, chloride, acetate, phosphate) aids in rehydration and correction of electrolyte disturbances.
Dextrose serves as a source of calories and water for hydration, and is metabolized to carbon dioxide and water, yielding energy. Potassium chloride provides potassium ions to maintain electrolyte balance, necessary for nerve conduction, muscle contraction, and acid-base regulation. The combination replenishes fluid and electrolytes in patients with hypokalemia and dehydration.
Intravenous administration; dosing is based on fluid and electrolyte requirements, typically 1-2 L per 24 hours for adults, infused at a rate of 100-200 mL/hour, adjusted according to clinical status and serum electrolyte levels.
Intravenous infusion of 1000-2000 mL/day (providing 50-100 g dextrose and 1.5-3 g potassium chloride) at a rate of 50-100 mL/hour; adjust based on fluid and electrolyte requirements.

Dextrose: terminal elimination half-life is approximately 2-3 hours in non-diabetic individuals, reflecting glucose utilization and storage; prolonged in renal impairment due to decreased clearance of metabolites. Electrolytes: half-life varies; sodium and chloride have elimination half-lives of 6-12 hours; potassium half-life is 12-24 hours; magnesium half-life is 24-48 hours; acetate half-life is minutes (rapid metabolism).
Dextrose: not applicable (rapidly metabolized). Potassium: distribution half-life ~1 h, terminal half-life ~8 h (in patients with normal renal function); prolonged in renal impairment.
Dextrose is completely metabolized to carbon dioxide and water in the presence of insulin; minimal renal excretion (<5%) as unchanged glucose in normoglycemic individuals. Electrolytes (sodium, chloride, potassium, magnesium, acetate, gluconate) are primarily excreted renally; renal elimination accounts for >90% of sodium and chloride, ~80% of potassium, and ~70% of magnesium. Acetate is rapidly metabolized to bicarbonate. Gluconate is partially excreted renally and partially metabolized.
Potassium: >90% renal (glomerular filtration and tubular secretion). Dextrose: metabolized to CO2 and water; negligible renal excretion (<5%).
