Head-to-head clinical analysis: MANNITOL 5 versus OSMITROL 15 IN WATER.
MANNITOL 5% 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 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; increases plasma osmolality, drawing water from extravascular to intravascular space, thereby reducing intracranial and intraocular pressure.
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.
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: 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 to 24–36 hours in anuria or severe renal impairment.
Renal: 90% unchanged; biliary/fecal: negligible (<2%)
Primarily renal excretion as unchanged drug; >97% eliminated by glomerular filtration within 24 hours. Minimal biliary/fecal elimination (<3%).
