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 necessary for the conduction of nerve impulses, maintenance of normal cardiac rhythm, and contraction of skeletal and smooth muscle. Dextrose provides calories and is a source of glucose for cellular metabolism. Sodium chloride provides sodium and chloride ions, maintaining 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: 10-20 mEq per hour, not exceeding 40 mEq in 4 hours; maximum 150 mEq per day; dose based on potassium deficit and serum potassium level.

Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Not applicable for potassium; distribution half-life ~0.5-1 h; elimination depends on renal function; in normal renal function, plasma potassium decline follows biphasic pattern with terminal half-life ~2-4 h.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
Renal: >90% as potassium ions; fecal: <10%; minimal biliary elimination.
