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, which are essential for maintaining intracellular osmolarity, nerve impulse transmission, cardiac and skeletal muscle contraction, and acid-base balance. Dextrose provides glucose for cellular metabolism, and sodium chloride provides sodium and chloride ions for extracellular fluid volume and osmolality maintenance.
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 clinical condition; typical adult maintenance: 100-200 mL/hour, not to exceed 300 mL/hour. Each liter provides potassium 1.5 g (20 mEq), dextrose 100 g, and sodium chloride 9 g (154 mEq Na+).

Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Potassium: Not applicable; dextrose: 1-2 h (terminal phase); sodium and chloride: not applicable due to homeostatic regulation.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
Renal: >90% of potassium, chloride, and sodium ions are excreted via kidneys; glucose is fully metabolized or excreted renally if exceeds renal threshold (typically <1% unchanged).
