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 0.45% (half-normal saline) is an isotonic crystalloid solution that provides sodium and chloride ions to maintain or restore extracellular fluid volume. It expands intravascular volume, corrects electrolyte imbalances, and can dilute plasma osmolality. The chloride component helps maintain acid-base balance.
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; adult: 500-1000 mL at a rate of 50-100 mL/hour (maintenance); adjust based on fluid and electrolyte status.

"The serum concentration of Levofloxacin can be decreased when it is combined with Magnesium sulfate."
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
Not applicable; sodium and chloride ions are endogenous substances with rapid renal regulation; no defined half-life.
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
Renal: >90% as sodium and chloride ions; negligible biliary/fecal elimination.
