Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides a source of calories and hydration, preventing ketosis and promoting glycogen deposition. Sodium chloride maintains extracellular fluid volume and electrolyte balance.
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.
Adult: Intravenous infusion at a rate determined by clinical condition, typically 100-200 mL/hour for maintenance; maximum infusion rate 25 g/hour (500 mL/hour). Dose individualized based on fluid, electrolyte, and glucose needs.
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: <15 minutes due to rapid cellular uptake and metabolism; sodium and chloride: no defined half-life as electrolytes are homeostatically regulated.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Renal; dextrose is metabolized to CO2 and water; sodium and chloride are excreted renally with >90% reabsorption under normal conditions.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
