Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Provides exogenous glucose for cellular energy metabolism and corrects electrolyte imbalances. Sodium and chloride maintain osmotic pressure and acid-base balance. Potassium is essential for nerve conduction, muscle contraction, and intracellular enzyme 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: 1000-2000 mL/day as maintenance, adjusted based on fluid, electrolyte, and energy 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.

Potassium: approximately 1-1.5 hours (distribution phase) with a terminal elimination half-life of about 8-12 hours in renal impairment. Dextrose: effectively infinite as it is metabolized; sodium and chloride follow body regulation with no defined half-life.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Components are eliminated via renal excretion: glucose is metabolized and excreted as CO2 and water; sodium, chloride, and potassium are excreted renally with over 90% of infused potassium appearing in urine within 24 hours.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
