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 crystalloid solution that increases intravascular volume by replacing extracellular fluid and electrolytes. It does not have a specific molecular target; its primary pharmacological effect is osmotic expansion of the vascular compartment.
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 injection of 10 mL of 0.9% sodium chloride solution for cardiac output determination via thermodilution, repeated as needed every 3-5 minutes for up to 3 injections per measurement set.

Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Not applicable as a conventional drug; sodium and chloride are endogenous electrolytes. The infused ions are distributed and eliminated according to body homeostasis. The plasma half-life of an infused sodium load is approximately 30-60 minutes in euvolemic individuals, but is highly variable based on renal function and volume status.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
Primarily renal (>95%). Sodium and chloride ions are freely filtered at the glomerulus and undergo variable tubular reabsorption depending on volume status; excess is excreted unchanged in urine. Fecal and biliary elimination are negligible.
