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 maintenance of electrolyte balance and normal cellular function. Sodium chloride provides sodium and chloride ions to maintain extracellular fluid volume and osmolarity.
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. The typical adult dose is 20-40 mEq of potassium per day, administered as an infusion rate not exceeding 10 mEq/hour or 0.5 mEq/kg/hour. Concentration is 0.11% KCl (1.46 mEq/L) provided in 0.9% NaCl.

Clinical Note
moderateMagnesium sulfate + Gatifloxacin
"The serum concentration of Gatifloxacin can be decreased when it is combined with Magnesium sulfate."
Clinical Note
moderateMagnesium sulfate + Rosoxacin
"The serum concentration of Rosoxacin can be decreased when it is combined with Magnesium sulfate."
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
Not applicable; potassium is a physiologic ion with rapid equilibration; serum levels reflect total body stores and renal function; in anephric patients, half-life extends to 30-50 hours.
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
Primarily renal (>90%) as potassium ions; negligible biliary/fecal elimination under normal conditions.
