MANNITOL 20% vs OSMITROL 5% IN WATER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Increases plasma osmolality, drawing water from intracellular and interstitial spaces into the extracellular fluid, thereby reducing intracranial pressure and promoting diuresis.
Osmotic diuretic that increases plasma osmolality, drawing water from intracellular and interstitial spaces into the extracellular compartment, thereby reducing cerebral edema and intraocular pressure; also promotes diuresis by increasing renal tubular fluid osmolality.
Adult: 50-100 g intravenously as a 20% solution over 30-60 minutes. For cerebral edema: 0.25-1 g/kg IV over 30-60 minutes. For oliguric acute kidney injury: test dose 0.2 g/kg IV over 3-5 minutes.
50-100 g intravenously as a 5% solution over 30-60 minutes; may repeat every 6-8 hours as needed. Maximum dose: 200 g in 24 hours.

Terminal elimination half-life 1.1–1.6 hours in normal renal function; prolonged to 18–36 hours in anuria/end-stage renal disease.
Approximately 0.25-1.5 hours (15-90 minutes); prolonged in renal impairment or with mannitol accumulation (e.g., in anuria).
Renal, >90% unchanged by glomerular filtration; negligible biliary (<2%) or fecal elimination.
Primarily renal (90-100% unchanged in urine); negligible biliary or fecal elimination.
