Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that provides caloric support and corrects hypoglycemia; sodium chloride replaces sodium and chloride ions to maintain electrolyte balance; potassium chloride replaces potassium for maintenance of normal cellular function.
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, typical adult dose: 1000-2000 mL per 24 hours, rate adjusted based on fluid and electrolyte status. Potassium chloride content provides 15 mEq per liter; infusion rate should not exceed 10-20 mEq/hr potassium.
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.

Glucose: rapid, <15 min (physiologic turnover); Potassium: 6-8 h (intracellular redistribution phase); Sodium: prolonged, 24-48 h (dependent on renal function).
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Glucose is metabolized to carbon dioxide and water; potassium is primarily eliminated renally (90-95%) with minor fecal loss; sodium and chloride are excreted renally according to homeostasis.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
