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 osmolarity, acid-base balance, and nerve impulse transmission; dextrose is a carbohydrate source for energy metabolism; sodium chloride provides sodium and chloride ions for extracellular fluid 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, 1000 mL to 2000 mL per 24 hours, adjusted based on serum potassium, glucose, and sodium levels.
