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.
Mannitol increases plasma osmolality, drawing water from tissues into the intravascular space via osmotic gradient, thereby reducing intracranial pressure and promoting diuresis. Dextrose provides caloric support. Sodium chloride provides electrolytes.
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: 50 to 100 g (333-667 mL) initially, then 50 g (333 mL) every 4-6 hours to maintain urine output of 30-50 mL/hr. Administer as a 15% solution with dextrose 5% in 0.45% sodium chloride.

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
Mannitol: 0.5-1.5 hours in normal renal function; prolonged to 24-48 hours in anuria; dextrose: 1-2 hours; negligible for sodium chloride.
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
Renal excretion of unchanged mannitol: 80-90% within 24 hours; dextrose is fully metabolized; sodium chloride is renally excreted.
