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 23.4% is a hypertonic saline solution that increases serum osmolality, drawing water from intracellular space into extracellular space, thereby expanding intravascular volume and reducing cerebral edema. It also acts as an 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.
IV: 50-100 mL of 23.4% sodium chloride (11.7-23.4 g NaCl) infused over 1-2 hours for hyponatremia; rate not to exceed 0.5 mEq/L/h correction.

Clinical Note
moderateMagnesium sulfate + Gatifloxacin
"The serum concentration of Gatifloxacin can be decreased when it is combined with Magnesium sulfate."
Clinical Note
moderateMagnesium sulfate + Rosoxacin
"The serum concentration of Rosoxacin can be decreased when it is combined with Magnesium sulfate."
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 as a terminal elimination half-life; sodium and chloride are electrolytes regulated by homeostatic mechanisms; plasma concentrations normalize within minutes to hours depending on volume status and renal function.
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
Renal; >95% of administered sodium and chloride ions excreted unchanged in urine via glomerular filtration and tubular reabsorption/regulation; negligible biliary/fecal elimination.
