Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides a source of calories and fluid, correcting hypoglycemia. Sodium chloride and potassium chloride replenish electrolytes and maintain osmotic 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.
Intravenous infusion: 1000 mL administered at a rate of 125 mL/hour over 8 hours; typical dosing range 1-3 L per 24 hours titrated based on electrolyte levels, fluid status, and clinical response.
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.

The components do not have a classical half-life. Dextrose has a distribution half-life of a few minutes and an elimination half-life of approximately 1-2 hours due to cellular uptake and metabolism. Sodium and chloride have a volume-dependent half-life; potassium's elimination half-life is approximately 12-24 hours, prolonged in renal impairment.
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 carbon dioxide and water, with negligible renal excretion. Sodium and chloride are primarily excreted renally, with >90% eliminated unchanged; potassium is >90% renally excreted, with minor fecal (approximately 5%) and negligible biliary elimination.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
