Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that provides caloric support and helps correct hypoglycemia. Sodium chloride is an electrolyte that maintains osmotic balance and fluid volume.
Magnesium sulfate causes decreased release of acetylcholine at the neuromuscular junction, reducing muscle contractility. It also blocks calcium channels, leading to vasodilation and anticonvulsant effects.
Intravenous infusion; dosage depends on fluid and electrolyte requirements. Typical maintenance: 75-150 mL/kg/day for adults, administered as continuous infusion.
IV: 1-4 g as a 10-20% solution, rate not exceeding 1 g/min; for eclampsia: 4-5 g IV bolus then 1-2 g/hour IV infusion.

Not applicable for dextrose as it is rapidly metabolized; plasma glucose half-life is approximately 1.7-2.0 hours after IV infusion but highly variable depending on metabolic demand and insulin activity. For sodium chloride, ions are continuously regulated by renal handling; no traditional half-life.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Dextrose is metabolized to CO2 and water via glycolysis and the Krebs cycle; negligible renal excretion (<5%). Sodium chloride is excreted renally with sodium and chloride ions freely filtered and variably reabsorbed (99% reabsorption under normal conditions, but excretion increases with excess intake).
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
