MANNITOL 10% vs OSMITROL 5% 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 and interstitial spaces into the extracellular compartment, thereby reducing cerebral edema and intraocular pressure; also promotes diuresis by increasing renal tubular fluid osmolality.
0.25-2 g/kg intravenously as a 10% solution over 30-60 minutes, typically 50-100 g every 6-8 hours.
50-100 g intravenously as a 5% solution over 30-60 minutes; may repeat every 6-8 hours as needed. Maximum dose: 200 g in 24 hours.

Terminal half-life: 1.1–1.6 hours; prolonged to 6–36 hours in renal impairment
Approximately 0.25-1.5 hours (15-90 minutes); prolonged in renal impairment or with mannitol accumulation (e.g., in anuria).
Renal: 90% as unchanged drug; <10% metabolized in liver to fructose and glucose; fecal: negligible
Primarily renal (90-100% unchanged in urine); negligible biliary or fecal elimination.
