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 is an osmotic diuretic that increases plasma osmolality, drawing water from extravascular spaces (e.g., brain, eyes) into the intravascular compartment and enhancing water excretion by the kidneys. Dextrose provides caloric supplementation, and sodium chloride provides electrolytes to maintain tonicity.
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. For osmotic diuresis: 50-100 g (1000-2000 mL of this solution) over 1-2 hours, total dose not exceeding 200 g/day. For reduction of intracranial pressure: 1.5-2 g/kg as a 20-25% solution given IV over 30-60 minutes. This 5% solution is not typically used for ICP reduction due to dilution.

Terminal 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: 0.25–1.5 hours (approximately 15–90 minutes); prolonged in renal impairment. Dextrose: <30 minutes (endogenous regulation).
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
Renal: >90% mannitol excreted unchanged in urine; dextrose is fully reabsorbed or metabolized; sodium chloride is handled by renal tubules.
