Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Provides free water and sodium chloride to expand extracellular fluid volume and correct electrolyte imbalances. Dextrose is metabolized to carbon dioxide and water, providing calories and preventing ketosis. Sodium chloride dissociates into sodium and chloride ions, maintaining osmotic pressure and acid-base balance.
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.
Intravenous infusion; dose determined by fluid and electrolyte requirements. Typical adult: 500-1000 mL at 50-100 mL/hour, adjusted based on clinical status.
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.

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
moderateDextrose: not applicable (endogenous substrate); glucose half-life ~1.5–2 hours in circulation under normal conditions, prolonged in hyperglycemia. Sodium chloride: not applicable as ions are electrolytes with no elimination half-life; renal clearance depends on glomerular filtration and tubular reabsorption.
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
Dextrose is fully metabolized to carbon dioxide and water; no significant renal excretion of intact dextrose. Sodium chloride is excreted renally; sodium and chloride ions are eliminated via kidneys, with excretion proportional to intake and renal function. No biliary or fecal elimination of intact components.
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
