OSMITROL 10% IN WATER vs SORBITOL-MANNITOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Osmotic diuretic that increases plasma osmolality, drawing water from intracellular spaces into extracellular fluid and increasing renal blood flow, thereby enhancing water excretion.
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.
0.25-2 g/kg intravenously over 30-60 minutes, repeated every 6-12 hours as needed. Maximum dose: 2 g/kg per dose or 200 g daily.
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 in renal impairment.
Terminal elimination half-life is approximately 4-6 hours; may be prolonged in renal impairment.
Renal: >90% excreted unchanged by glomerular filtration with minimal tubular reabsorption. Negligible biliary/fecal elimination.
Primarily renal excretion as unchanged drug; >90% eliminated via urine within 24 hours.
