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 expands extracellular fluid volume, replacing sodium and chloride deficits. Sodium is the primary cation maintaining osmotic pressure and acid-base balance; chloride is the major extracellular anion. The solution provides electrolyte replacement and hydration without altering serum osmolality.
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, 100-200 mL/hour for maintenance; up to 1000 mL bolus for volume resuscitation in adults.

Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Not applicable; sodium and chloride ions are endogenous substances with no defined terminal elimination half-life. Excretion half-life is dependent on renal function, typically 6-12 hours in individuals with normal kidney function.
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
Renal: >95% of administered sodium and chloride ions are excreted unchanged in urine; fecal and biliary elimination are negligible (<1%).
