Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Potassium chloride provides potassium ions essential for nerve impulse transmission, muscle contraction, and acid-base balance. Dextrose supplies glucose for cellular energy. Sodium chloride restores sodium and chloride ions for fluid and electrolyte balance.
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.
Intravenous infusion, rate determined by serum electrolyte levels and fluid requirements; typical adult dose: 1 mL/kg/hour, providing potassium at 0.11 g (1.5 mEq) per 100 mL, dextrose 5 g per 100 mL, and sodium chloride 0.33 g per 100 mL.

Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Potassium: not applicable as a terminal half-life; distribution and elimination follow body potassium homeostasis. Dextrose and sodium chloride are rapidly distributed and eliminated with half-lives of minutes to hours.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
Potassium: primarily renal (>90% as K+), with minimal biliary/fecal elimination (<2%). Dextrose and sodium chloride are metabolized or excreted renally.
