Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Sodium chloride 0.9% is an isotonic solution that provides sodium and chloride ions, essential for maintenance of osmotic pressure and fluid balance. It acts as a volume expander and vehicle for drug administration.
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).
Intravenous infusion; 0.9% sodium chloride is administered at a rate and volume determined by the patient's fluid and electrolyte needs, typically 500-1000 mL per hour for resuscitation or 100-200 mL per hour for maintenance.

Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
The terminal elimination half-life of sodium and chloride ions is approximately 8-12 hours in individuals with normal renal function, reflecting the time required to excrete a load and reestablish homeostasis. In renal impairment, half-life is prolonged proportionally to the decrease in glomerular filtration rate.
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
Primarily renal excretion; >90% of administered sodium and chloride ions are eliminated unchanged in urine via glomerular filtration and tubular reabsorption. Less than 10% is lost through sweat, feces, and insensible losses.
