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 for maintaining intracellular osmolality, acid-base balance, nerve conduction, and muscle contraction. Dextrose is a monosaccharide that provides calories and may reduce protein and nitrogen loss. Sodium chloride provides sodium and chloride ions for fluid and electrolyte balance.
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 not exceeding 10 mEq/hour of potassium chloride; typical adult dose is 20-40 mEq potassium in 500-1000 mL of solution infused over 4-8 hours, adjusting based on serum potassium 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; potassium is an electrolyte with no classic half-life. Dextrose half-life is ~15-20 min; sodium chloride half-life is ~1-2 weeks for total body sodium. Plasma potassium clearance depends on renal function.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
Primarily renal (90-95% as potassium ion); minimal biliary/fecal elimination; excretion of dextrose and sodium chloride components is also renal.
