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.
Potassium chloride provides potassium ions for maintaining intracellular tonicity, cellular metabolism, nerve impulse transmission, and muscle contraction. Dextrose 5% provides a source of calories and water for hydration. Sodium chloride 0.225% provides sodium and chloride ions to maintain electrolyte balance and osmotic pressure.
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 at a rate not exceeding 10 mEq/hour; typical dose 10-20 mEq over 1-2 hours, may repeat as needed. Maximum 40 mEq per dose, 200 mEq per day.

Clinical Note
moderateMagnesium sulfate + Levofloxacin
"The serum concentration of Levofloxacin can be decreased when it is combined with Magnesium sulfate."
Clinical Note
moderateTerminal 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 has no defined terminal elimination half-life as it is an electrolyte regulated by homeostasis; redistribution half-life is approximately 4–6 hours. In renal impairment, elimination is prolonged.
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
Renal excretion: potassium is primarily eliminated by the kidneys; approximately 90% of potassium intake is excreted renally, with the remainder via feces (10%) and negligible biliary elimination.
