MANNITOL 20% vs OSMITROL 10% 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 spaces into extracellular fluid and increasing renal blood flow, thereby enhancing water excretion.
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.
0.25-2 g/kg intravenously over 30-60 minutes, repeated every 6-12 hours as needed. Maximum dose: 2 g/kg per dose or 200 g daily.

Terminal elimination half-life 1.1–1.6 hours in normal renal function; prolonged to 18–36 hours in anuria/end-stage renal disease.
Terminal elimination half-life is approximately 0.25–1.5 hours in patients with normal renal function, prolonged in renal impairment.
Renal, >90% unchanged by glomerular filtration; negligible biliary (<2%) or fecal elimination.
Renal: >90% excreted unchanged by glomerular filtration with minimal tubular reabsorption. Negligible biliary/fecal elimination.
