Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Magnesium sulfate acts as a physiological calcium channel blocker. It inhibits calcium influx into presynaptic nerve terminals, reducing acetylcholine release at the neuromuscular junction and decreasing muscle contraction. It also antagonizes NMDA receptors and stabilizes neuronal membranes.
Dextrose 5% provides free water and calories to correct carbohydrate depletion and osmotic diuresis. Potassium chloride replaces potassium ions to maintain cellular membrane potential, nerve impulse conduction, and muscle contraction. Sodium chloride 0.11% provides sodium and chloride ions to maintain extracellular fluid volume and osmolality.
IV: Loading dose 4-6 g over 20-30 minutes, followed by maintenance infusion 1-2 g/hour for seizure prophylaxis in severe preeclampsia/eclampsia. IM: 4-8 g deep IM initially, then 4 g every 4 hours as needed.
Intravenous infusion; rate and volume determined by electrolyte needs and fluid status. Typical maintenance: 1-2 mEq/kg/day potassium chloride, administered at a rate not exceeding 10-20 mEq/h via peripheral line or up to 40 mEq/h via central line. This product provides 0.037% KCl (5 mEq/L), 5% dextrose, and 0.11% NaCl (19 mEq/L Na+).

Terminal elimination half-life approximately 4-6 hours in patients with normal renal function; prolonged to 12-24 hours or more in renal impairment, necessitating dose adjustment
Potassium: not applicable as an element; distribution half-life ~1 h. Dextrose: minutes. Sodium: regulated with t1/2 of ~1-2 h for acute load.
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
Renal: >90% of potassium is excreted via kidneys, with minor fecal loss (~10%). Dextrose and sodium are fully metabolized or renally excreted.
