MANNITOL 20% IN PLASTIC CONTAINER 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 compartments into extracellular fluid. In the kidneys, it is freely filtered at the glomerulus but minimally reabsorbed, increasing tubular fluid osmolality and reducing water reabsorption, thereby promoting diuresis. It also reduces cerebral edema by creating an osmotic gradient that draws 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.
Intravenous: 50-100 g (250-500 mL of 20% solution) over 30-60 minutes; may repeat every 6-8 hours as needed. For cerebral edema: 1-2 g/kg IV over 30-60 minutes.
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 elimination half-life: 0.25–1.7 hours in normal renal function; prolonged 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. Biliary/fecal: negligible.
Renal: >90% excreted unchanged by glomerular filtration with minimal tubular reabsorption. Negligible biliary/fecal elimination.
