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 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: 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, 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+).

Terminal 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
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 (90-95% as unchanged drug); minor biliary/fecal (<5%)
Renal: >95% as chloride and sodium ions; potassium ions also excreted renally (90% reabsorbed, remainder excreted). Biliary/fecal: negligible (<5%).
