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 replenishes intracellular potassium, essential for maintaining membrane potential and neuromuscular function. Dextrose provides a carbohydrate source to prevent hypoglycemia. Sodium chloride maintains osmotic balance and electrolyte homeostasis.
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. The rate of administration and total volume depend on the patient's fluid and electrolyte needs. Typically, the dose is 10 mEq of potassium chloride per liter of fluid, infused at a rate not exceeding 10 mEq/hour (or 20 mEq/hour in severe hypokalemia) via central line. Maximum daily dose: 200 mEq.

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 by first-order kinetics. Serum potassium half-life is approximately 30 minutes due to rapid distribution and renal excretion, but depends on renal function and total body stores.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
Renal: >90% as potassium ions. Fecal: <10% via unabsorbed potassium.
