Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Provides free water and sodium chloride to expand extracellular fluid volume and correct electrolyte imbalances. Dextrose is metabolized to carbon dioxide and water, providing calories and preventing ketosis. Sodium chloride dissociates into sodium and chloride ions, maintaining osmotic pressure and acid-base balance.
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; dose determined by fluid and electrolyte requirements. Typical adult: 500-1000 mL at 50-100 mL/hour, adjusted based on clinical status.
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 (endogenous substrate); glucose half-life ~1.5–2 hours in circulation under normal conditions, prolonged in hyperglycemia. Sodium chloride: not applicable as ions are electrolytes with no elimination half-life; renal clearance depends on glomerular filtration and tubular reabsorption.
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Dextrose is fully metabolized to carbon dioxide and water; no significant renal excretion of intact dextrose. Sodium chloride is excreted renally; sodium and chloride ions are eliminated via kidneys, with excretion proportional to intake and renal function. No biliary or fecal elimination of intact components.
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
