Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that provides calories and serves as a source of glucose, which is utilized for cellular energy metabolism. Sodium chloride provides sodium and chloride ions to maintain electrolyte balance and osmotic pressure. Potassium chloride provides potassium ions essential for cellular functions, including nerve conduction and muscle contraction, and helps correct or prevent hypokalemia.
Magnesium sulfate provides magnesium ions, which are essential for various physiological processes. It acts as a cofactor for enzymatic reactions, stabilizes excitable membranes, and antagonizes calcium entry at the neuromuscular junction, leading to reduced acetylcholine release and muscle relaxation. In the CNS, it may act as a noncompetitive antagonist of NMDA receptors, exerting anticonvulsant effects.
Intravenous infusion: 1000-2000 mL/day (25-50 mL/kg/day) titrated to fluid and electrolyte needs; maximum infusion rate 0.5 g/kg/hour dextrose.
1 to 4 g intravenously as a 5% to 20% solution, rate not exceeding 150 mg/min; dosing frequency depends on indication (e.g., preeclampsia/eclampsia: 4-5 g IV loading then 1-2 g/hr infusion; hypomagnesemia: 1-2 g IV over 1-2 hours, may repeat based on serum magnesium levels).

Dextrose: not applicable as it is rapidly metabolized; glucose half-life is approximately 1.5-2 hours in normal individuals, prolonged in diabetes. Sodium and potassium: not defined as they are regulated by renal function.
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Dextrose is metabolized to carbon dioxide and water; <1% excreted unchanged in urine. Sodium chloride and potassium chloride are excreted renally; >90% of filtered sodium and potassium is reabsorbed, with excretion balancing intake via renal regulation. Biliary/fecal excretion is negligible.
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
