MANNITOL 10% IN PLASTIC CONTAINER vs OSMITROL 20% IN WATER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mannitol is an osmotic diuretic that increases plasma osmolarity, drawing water from tissues into the bloodstream and enhancing water excretion by the kidneys. It also reduces intracranial pressure by creating an osmotic gradient across the blood-brain barrier.
Osmotic diuretic that increases plasma osmolality, drawing water from intracellular spaces into extracellular fluid and increasing renal tubular osmotic pressure, which inhibits water reabsorption and promotes diuresis.
Adults: 50-100 g intravenously over 30-60 minutes, typically as a 15-25% solution. For reduction of intracranial pressure, 1.5-2 g/kg as a 20% solution IV over 30-60 minutes. For promotion of diuresis, 50-100 g as a 5-25% solution IV.
1-2 g/kg (5-10 mL/kg of 20% solution) intravenously over 30-60 minutes for reduction of intracranial pressure; may repeat every 6-8 hours. For preoperative bowel preparation, 100-200 mL (20% solution) orally.

Terminal elimination half-life is 0.25–1.5 hours; prolonged in renal impairment (up to 36 hours).
0.25–1.5 hours (15–90 minutes) in patients with normal renal function. In oliguric or anuric patients, half-life is markedly prolonged, up to 36 hours, due to reduced clearance.
Renal: >90% as unchanged drug; minimal biliary or fecal excretion.
Primarily renal excretion as unchanged drug. Over 90% of administered dose is excreted unchanged in urine within 24 hours. Less than 5% is metabolized in the liver; negligible biliary/fecal elimination.
