Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that serves as a source of calories and water for intravenous administration. It is metabolized to carbon dioxide and water via glycolysis and the citric acid cycle, providing energy. Sodium chloride provides sodium and chloride ions to maintain electrolyte balance and osmotic pressure.
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; rate and volume determined by fluid and electrolyte needs, typically 100-200 mL/hour for maintenance, not to exceed 50 mL/kg/day to avoid fluid overload.
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.

Dextrose: functional half-life ~2 hours (rapid cellular uptake). Sodium: ~6-12 hours (renal regulation). Chloride: parallels sodium. Clinical context: elimination is rapid with normal renal function.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Renal: Dextrose is completely metabolized; sodium and chloride are eliminated renally. Excretion of water follows urine output. No biliary or fecal elimination.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
