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% and potassium chloride 0.3% in plastic container provides isotonic crystalloid solution for resuscitation and maintenance of extracellular fluid volume. Sodium chloride restores sodium and chloride deficits, while potassium chloride replenishes potassium, essential for maintaining cellular membrane potential, nerve conduction, and muscle contraction, including cardiac function.
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, rate and volume determined by clinical need: typical adult dose is 1-2 L/day for maintenance or replacement, up to 3-4 L/day for deficits; maximum infusion rate 1 L/hour under continuous monitoring. Contains 0.9% sodium chloride (154 mEq/L Na+, Cl-) and 0.3% potassium chloride (40 mEq/L K+).

Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Sodium and chloride: 6–12 hours (tissue distribution equilibrium); potassium: 12–24 hours (slow exchange from intracellular stores). Clinical context: half-life prolonged in renal impairment.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
Renal: >95% as chloride and sodium ions; potassium ions also excreted renally (90% reabsorbed, remainder excreted). Biliary/fecal: negligible (<5%).
