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, essential for maintaining cellular membrane potential, nerve impulse transmission, and muscle contraction. Dextrose provides a source of calories and energy. Sodium chloride provides sodium and chloride ions for electrolyte balance and fluid distribution.
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. Rate and volume determined by patient's fluid and electrolyte needs; typical adult maintenance: 100-200 mL/h (providing K+ 1.5-3 mEq/h).

Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Potassium: 1-1.5 hours (rapid redistribution); clinical context: steady-state achieved in 24-48 hours with continuous infusion; elimination half-life prolonged in renal impairment.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
Primarily renal (>90%); potassium is filtered and actively secreted in distal tubules; negligible fecal or biliary elimination. Dextrose and sodium are metabolized or renally eliminated.
