OSMITROL 15% IN WATER vs SORBITOL-MANNITOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Osmotic diuretic; increases plasma osmolality, drawing water from extravascular to intravascular space, thereby reducing intracranial 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.
IV infusion of 50-200 g over 30-60 minutes as a 15% solution; typical adult dose is 1.5-2 g/kg every 6-8 hours.
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 elimination half-life is approximately 0.25–1.5 hours in patients with 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.
Primarily renal excretion as unchanged drug; >97% eliminated by glomerular filtration within 24 hours. Minimal biliary/fecal elimination (<3%).
Primarily renal excretion as unchanged drug; >90% eliminated via urine within 24 hours.
