Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose 5% provides a source of calories and water for hydration, correcting hypoglycemia by increasing blood glucose levels. Sodium chloride 0.45% and potassium chloride 5 mEq restore electrolyte balance: sodium and chloride are essential for maintenance of extracellular fluid volume and acid-base balance; potassium is critical for neuromuscular function, cardiac contractility, and intracellular 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 at a rate determined by fluid and electrolyte requirements; typical adult dose is 1000-2000 mL over 24 hours, not exceeding 50 mL/kg/day.
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: ~1.5-2.5 minutes (rapid cellular uptake). Sodium/potassium: hours to days (depends on total body stores and renal function); in renal failure, half-life is prolonged.
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, not excreted unchanged; sodium and potassium are primarily excreted renally (>90% of load), with minor fecal loss (<5%).
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
