MANNITOL 5% 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 plasma osmolality, drawing water from intracellular spaces into the extracellular fluid and vasculature, thereby reducing intracranial and intraocular pressure. It also increases renal tubular osmotic pressure, inhibiting water reabsorption and promoting diuresis.
Osmotic diuretic that increases plasma osmolality, drawing water from intracellular spaces into extracellular fluid and increasing renal blood flow, thereby enhancing water excretion.
Intravenous infusion of 50-100 g (as a 5% solution) over 2-6 hours, typically 500-1000 mL, for osmotic diuresis; or for reduction of intracranial pressure, 1-2 g/kg IV over 30-60 minutes as a 15-25% solution.
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: 0.25–1.5 h (prolonged in renal impairment); clinical context: accumulates in renal failure, monitor serum osmolarity and renal function
Terminal elimination half-life is approximately 0.25–1.5 hours in patients with normal renal function, prolonged in renal impairment.
Renal: 90% unchanged; biliary/fecal: negligible (<2%)
Renal: >90% excreted unchanged by glomerular filtration with minimal tubular reabsorption. Negligible biliary/fecal elimination.
