OSMITROL 15% IN WATER IN PLASTIC CONTAINER vs SORBITOL-MANNITOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Sorbitol and mannitol are sugar alcohols that act as osmotic diuretics. They are filtered by the glomerulus but not reabsorbed, increasing osmotic pressure in the tubular lumen, thereby reducing water reabsorption and promoting diuresis. They also increase intraocular pressure and decrease intracranial pressure by drawing water from tissues into the bloodstream.
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.
Osmotic diuretic; 50-100 g (as 25% solution) IV over 30-60 minutes, may repeat every 6-12 hours as needed; maximum 200 g/day.

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.
Terminal elimination half-life is approximately 4-6 hours; may be prolonged in renal impairment.
Renal: >90% unchanged by glomerular filtration; minimal tubular reabsorption or secretion. <10% metabolized in liver (negligible).
Primarily renal excretion as unchanged drug; >90% eliminated via urine within 24 hours.
