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 for essential cellular functions, including maintenance of intracellular tonicity, nerve impulse conduction, cardiac and skeletal muscle contraction, and acid-base balance. Dextrose supplies glucose for cellular energy metabolism, and sodium chloride provides sodium and chloride ions to maintain extracellular fluid volume and osmolality.
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 patient's fluid and electrolyte needs; typical adult maintenance: 100-200 mL/hour, providing potassium at 1.5-3 mEq/hour, not to exceed 10 mEq/hour or 200 mEq/day.

Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Potassium: Not applicable (homeostatically regulated); dextrose: ~1-2 hours (exogenous insulin clearance); chloride: ~3-4 hours.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
Primarily renal excretion of potassium (90% via kidneys); chloride and dextrose components are metabolized or excreted renally. Less than 1% fecal.
