MANNITOL 25% vs OSMITROL 15% 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.
Osmotically active agent that increases plasma osmolality, drawing water from intracellular and interstitial spaces into the vascular compartment, thereby reducing cerebral edema and intraocular pressure.
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.
1.5-2 g/kg intravenous infusion over 30-60 minutes every 6-8 hours as needed for reduction of intracranial pressure or cerebral edema.

Terminal elimination half-life: 0.25–1.7 hours; prolonged in renal impairment.
Terminal half-life: 0.25–1.5 hours (15–90 minutes) in normal renal function; prolonged to 24–36 hours in anuria or severe renal impairment.
Renal: >90% unchanged by glomerular filtration; biliary/fecal: <5%.
Renal: >90% unchanged by glomerular filtration; minimal tubular reabsorption or secretion. <10% metabolized in liver (negligible).
