MANNITOL 20% IN PLASTIC CONTAINER vs OSMITROL 10% IN WATER IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mannitol is an osmotic diuretic that increases plasma osmolality, drawing water from intracellular compartments into extracellular fluid. In the kidneys, it is freely filtered at the glomerulus but minimally reabsorbed, increasing tubular fluid osmolality and reducing water reabsorption, thereby promoting diuresis. It also reduces cerebral edema by creating an osmotic gradient that draws water from brain tissue into plasma.
Increases plasma osmolality, drawing water from tissues into the bloodstream, thereby reducing intracranial pressure and cerebral edema.
Intravenous: 50-100 g (250-500 mL of 20% solution) over 30-60 minutes; may repeat every 6-8 hours as needed. For cerebral edema: 1-2 g/kg IV over 30-60 minutes.
Initial: 0.25–1 g/kg (25–100 mL of 10% solution) IV over 30–60 minutes. May repeat every 6–12 hours if needed. Typical adult dose: 50–100 g IV. Maximum: 2 g/kg per dose.

Terminal elimination half-life: 0.25–1.7 hours in normal renal function; prolonged in renal impairment.
Terminal half-life approximately 1.5 hours in normal renal function; prolonged in renal impairment (up to 36 hours in anuria).
Renal: >90% as unchanged drug. Biliary/fecal: negligible.
Primarily renal; >90% excreted unchanged in urine via glomerular filtration; <5% biliary/fecal.
