MANNITOL 10% vs OSMITROL 15% IN WATER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mannitol is an osmotic diuretic that increases urinary output by raising the osmolarity of glomerular filtrate, thereby reducing tubular reabsorption of water and solutes. It also reduces cerebral edema by creating an osmotic gradient across the blood-brain barrier, drawing water from brain tissue into plasma.
Osmotic diuretic; increases plasma osmolality, drawing water from extravascular to intravascular space, thereby reducing intracranial and intraocular pressure.
0.25-2 g/kg intravenously as a 10% solution over 30-60 minutes, typically 50-100 g every 6-8 hours.
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.

Terminal half-life: 1.1–1.6 hours; prolonged to 6–36 hours in renal impairment
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.
Renal: 90% as unchanged drug; <10% metabolized in liver to fructose and glucose; fecal: negligible
Primarily renal excretion as unchanged drug; >97% eliminated by glomerular filtration within 24 hours. Minimal biliary/fecal elimination (<3%).
