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 is the major intracellular cation. It is essential for the maintenance of intracellular tonicity, transmission of nerve impulses, contraction of cardiac, skeletal, and smooth muscle, and maintenance of normal renal function. Dextrose provides caloric support and sodium chloride provides electrolyte replacement.
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; dose depends on serum potassium level and clinical status. Typical adult dose: 20-40 mEq potassium chloride infused at a rate not exceeding 10-20 mEq/hour. The concentration in this product is 40 mEq/L, so infusion rate should be adjusted accordingly.

Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Not applicable; potassium is not eliminated via first-order kinetics. Homeostatic regulation maintains serum levels.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
Primarily renal (>90% as potassium ion). Minimal fecal/biliary elimination.
