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 is the principal extracellular cation and anion, respectively, in the body. It maintains osmotic pressure, fluid balance, and acid-base balance. It is essential for nerve conduction and muscle contraction.
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; dose and rate depend on patient's fluid and electrolyte status; typical maintenance: 0.9% NaCl at 1-2 mL/kg/h.

Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Terminal half-life is approximately 24-48 hours in healthy individuals, primarily reflecting renal sodium handling and total body sodium pool; significantly prolonged in renal impairment.
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
Renal: >95% unchanged via glomerular filtration and tubular reabsorption. Fecal/biliary: negligible.
