OSMITROL 15% IN WATER vs SORBITOL-MANNITOL IN PLASTIC CONTAINER
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 osmotic diuretics. They increase osmotic pressure in the glomerular filtrate, reducing water reabsorption and promoting diuresis. Mannitol also decreases intracranial and intraocular pressure by creating an osmotic gradient that draws water from tissues into the vasculature.
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.
Intravenous infusion of 50 mL of a 25% sorbitol-25% mannitol solution administered over 10–20 minutes; may repeat once after 6–8 hours if needed.

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.
Sorbitol: approximately 0.5-1 hour; mannitol: approximately 0.5-1.5 hours. In anuria, mannitol half-life may extend to 36 hours.
Primarily renal excretion as unchanged drug; >97% eliminated by glomerular filtration within 24 hours. Minimal biliary/fecal elimination (<3%).
Renal: >95% as unchanged sorbitol and mannitol; negligible biliary/fecal elimination.
