MAGNESIUM SULFATE vs SODIUM CHLORIDE 14.6%
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 14.6% is a hypertonic saline solution that increases serum osmolality, drawing water from the intracellular space into the extracellular compartment, thereby reducing cerebral edema and intracranial pressure. It also acts as a volume expander and electrolyte replenisher.
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 via central line; typical dose for severe hyponatremia is 100-150 mL over 20 minutes (150 mL max) for acute correction, then 0.5-1 mmol/L/hour increase not exceeding 8 mmol/L in 24 hours.

Clinical Note
moderateMagnesium sulfate + Levofloxacin
"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 homeostatically regulated with no defined terminal half-life. Rapidly redistributed and excreted, with clinical effect related to plasma concentration.
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
Renal: >90% as unchanged sodium and chloride ions; minor fecal (<5%) and negligible biliary elimination.
