DEXTROSE 5% AND SODIUM CHLORIDE 0.9% vs MAGNESIUM SULFATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose 5% provides a source of calories and fluid for hydration, preventing ketosis by providing a minimal carbohydrate source. Sodium chloride 0.9% supplies electrolytes and maintains osmotic pressure in extracellular fluid.
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; typical adult dose is 500-1000 mL as a single dose, administered at a rate determined by clinical condition (e.g., 100-200 mL/h for maintenance).
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
moderateGlucose has a plasma half-life of approximately 1.5-2.5 hours in normal individuals, reflecting rapid cellular uptake and metabolism. Sodium and chloride have no definable half-life as they are actively regulated; however, the half-life of infused sodium is approximately 2-4 hours depending on renal function.
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
Glucose is completely metabolized to CO2 and water; renal excretion of unchanged glucose is negligible (<1%) in normoglycemic patients. Sodium and chloride are primarily excreted renally (90-95% of infused load) with small fecal and sweat losses. In dextrose 5% and sodium chloride 0.9%, both components are eliminated renally; the dextrose is metabolized, not excreted unchanged.
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
