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 maintaining intracellular osmotic pressure, acid-base balance, and nerve impulse transmission. Dextrose 5% provides glucose for cellular metabolism, and sodium chloride 0.9% 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, 15 mEq potassium chloride in 5% dextrose and 0.9% sodium chloride at a rate not exceeding 10 mEq/hour; frequency based on serum potassium levels and clinical need.

Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Not applicable as potassium is an electrolyte with distribution and elimination dependent on body stores and renal function; in healthy individuals, clearance is rapid with no defined terminal half-life, but in renal impairment, half-life extends.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
Renal: >90% of potassium intake is excreted by the kidneys, primarily via distal tubular secretion; <10% fecal, minimal biliary.
