Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Magnesium sulfate acts as a physiological calcium channel blocker. It inhibits calcium influx into presynaptic nerve terminals, reducing acetylcholine release at the neuromuscular junction and decreasing muscle contraction. It also antagonizes NMDA receptors and stabilizes neuronal membranes.
Hypertonic sodium chloride solution (3%) increases extracellular osmolarity, drawing water from intracellular space into extracellular compartment via osmotic gradient, thereby reducing cerebral edema and intracranial pressure. Sodium ions also restore electrolyte balance in hyponatremia.
IV: Loading dose 4-6 g over 20-30 minutes, followed by maintenance infusion 1-2 g/hour for seizure prophylaxis in severe preeclampsia/eclampsia. IM: 4-8 g deep IM initially, then 4 g every 4 hours as needed.
Intravenous infusion of 3% sodium chloride at a rate of 1-2 mL/kg/hour, with a typical rate of 50-100 mL/hour for adults, titrated to serum sodium goals. Maximum infusion rate: 100 mL/hour, with careful monitoring of serum sodium (increase not >8-10 mEq/L per 24 hours).

Clinical Note
moderateTerminal elimination half-life approximately 4-6 hours in patients with normal renal function; prolonged to 12-24 hours or more in renal impairment, necessitating dose adjustment
Not applicable: sodium and chloride are endogenous electrolytes; administered dose mixes with body pools and is eliminated via renal excretion with a half-life dependent on renal function and hydration status. In euvolemic individuals with normal renal function, the terminal elimination half-life of excess sodium is approximately 6–12 hours.
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
Renal (essentially 100%): sodium and chloride ions are excreted unchanged in urine. No biliary or fecal elimination of intact drug; sodium and chloride are obligately filtered and variably reabsorbed based on volume status and renal function.
