MANNITOL 10% vs OSMITROL 10% 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 that increases plasma osmolality, drawing water from intracellular spaces into extracellular fluid and increasing renal blood flow, thereby enhancing water excretion.
0.25-2 g/kg intravenously as a 10% solution over 30-60 minutes, typically 50-100 g every 6-8 hours.
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.

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 in renal impairment.
Renal: 90% as unchanged drug; <10% metabolized in liver to fructose and glucose; fecal: negligible
Renal: >90% excreted unchanged by glomerular filtration with minimal tubular reabsorption. Negligible biliary/fecal elimination.
