Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides a source of calories and fluid for cellular metabolism. Sodium chloride and potassium chloride replace electrolyte deficits and maintain acid-base 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.
IV infusion; rate determined by fluid and electrolyte requirements. Typical adult dose: 1000-2000 mL per 24 hours, administered at 40-80 mL/hour.
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 minute (rapid uptake into cells); potassium: ~4-6 hours in a 70 kg adult with normal renal function; chloride: variable, follows sodium kinetics.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Excretion is primarily renal for potassium and chloride; dextrose is metabolized to CO2 and water. Potassium: >90% excreted in urine; chloride: >95% renally absorbed and excreted; dextrose: not excreted unchanged.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
