MAGNESIUM SULFATE vs SODIUM CHLORIDE
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.
Sodium chloride dissociates in body fluids into sodium and chloride ions, which are major determinants of extracellular fluid osmolality and volume. It maintains electrolyte balance, nerve impulse transmission, and muscle contraction.
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: 0.9% sodium chloride (normal saline) infusion at 50-100 mL/hour for maintenance; dose depends on indication (e.g., 500-1000 mL bolus for hypovolemia). Maximum rate: 1 L/hour in emergencies.

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
Variable and distribution-dependent; for acute changes, distribution half-life ~20 minutes; terminal half-life ~8-12 hours for total body sodium adjustment, clinically relevant for electrolyte correction
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
Primarily renal (>90%) via glomerular filtration and tubular reabsorption; negligible biliary/fecal elimination (<1%)
