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 replaces potassium ions lost from the body, maintaining cellular membrane potential and acid-base balance. Dextrose 5% provides a source of calories and water for hydration. Sodium chloride 0.9% replenishes sodium and chloride ions, restoring extracellular fluid volume and osmolarity.
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 at a rate of 10 mEq potassium chloride per hour, maximum 40 mEq per day, as needed to correct hypokalemia. Product is a fixed combination; typical administration is 1-2 L per day of the solution.

Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Potassium has a half-life of approximately 12-24 hours in healthy individuals, reflecting redistribution and renal elimination; prolonged in renal impairment. Dextrose has a half-life of <30 minutes due to rapid cellular uptake and metabolism.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
Potassium is primarily excreted renally (90%) via glomerular filtration and distal tubular secretion; about 10% is eliminated in feces via gastrointestinal secretion. Dextrose is fully metabolized to CO2 and water, while sodium and chloride are renally excreted with reabsorption regulated by renal function.
