Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Magnesium sulfate causes decreased release of acetylcholine at the neuromuscular junction, reducing muscle contractility. It also blocks calcium channels, leading to vasodilation and 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.
IV: 1-4 g as a 10-20% solution, rate not exceeding 1 g/min; for eclampsia: 4-5 g IV bolus then 1-2 g/hour IV infusion.
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.

Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
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 (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
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.
