Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides a source of calories and carbohydrate for metabolism, preventing ketosis and promoting protein-sparing. Sodium chloride provides electrolytes to maintain osmotic pressure and fluid 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: rate determined by patient's fluid and electrolyte needs; typical maintenance dose 30-100 mL/hour for adults. 10% dextrose provides 340 kcal/L. 0.33% NaCl provides 51 mEq/L Na+.
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: ~2.3 hours (intracellular utilization). Sodium chloride: not applicable; electrolytes are regulated homeostatically. Clinically, dextrose's half-life reflects rapid cellular uptake.
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
Renal: nearly 100% as free water and electrolytes. Dextrose is completely metabolized to CO2 and water; no significant biliary or fecal elimination.
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
