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 essential potassium ion for maintaining intracellular osmotic pressure, acid-base balance, and nerve conduction. Dextrose provides calories and increases serum glucose. Sodium chloride supplies sodium and chloride ions to maintain extracellular fluid volume and electrolyte balance.
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.
IV infusion: 10 mEq potassium chloride in 1000 mL D5 0.45% NaCl at a rate not exceeding 10 mEq/hour; maximum 40 mEq/hour with cardiac monitoring. Adult dose typically 20-40 mEq per day, adjusted based on serum potassium.

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 as potassium is an endogenous ion; serum half-life reflects redistribution and renal clearance, approximately 6-8 hours in normal renal function.
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
Renal: >90% as potassium ions, with minor fecal loss (<5%). Biliary excretion is negligible.
