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 cellular membrane potential, nerve impulse conduction, and muscle contraction. Dextrose 5% provides glucose for energy, and sodium chloride 0.9% restores sodium and chloride ions, maintaining 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.
Adults: Intravenous infusion at a rate not exceeding 10 mEq per hour. Typical dose 10-20 mEq potassium chloride in 100-1000 mL D5 0.9% NaCl, repeated as needed based on serum potassium and clinical status.

Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Potassium has no true elimination half-life as it is a mineral; its serum concentration is tightly regulated by renal function and cellular uptake. In anuric patients, half-life may exceed 24 hours.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
Renal: >90% of potassium is excreted by the kidneys, primarily via distal tubular secretion and reabsorption. Fecal: <10%. Biliary: negligible.
