MANNITOL 25% 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 osmolarity, drawing water from intracellular and interstitial spaces into the intravascular compartment. In the kidney, it is filtered but not reabsorbed, increasing tubular fluid osmolarity and promoting water excretion. It also reduces intracranial and intraocular pressure by creating an osmotic gradient.
Increases plasma osmolality, drawing water from tissues into the bloodstream, thereby reducing intracranial pressure and cerebral edema.
1-2 g/kg (4-8 mL/kg) intravenously as a 25% solution over 30-60 minutes; may repeat every 6-8 hours as needed.
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; 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% unchanged by glomerular filtration; biliary/fecal: <5%.
Primarily renal; >90% excreted unchanged in urine via glomerular filtration; <5% biliary/fecal.
