MANNITOL 20% IN PLASTIC CONTAINER 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 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; increases plasma osmolality, drawing water from extravascular to intravascular space, thereby reducing intracranial and intraocular pressure.
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.
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 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 to 24–36 hours in anuria or severe renal impairment.
Renal: >90% as unchanged drug. Biliary/fecal: negligible.
Primarily renal excretion as unchanged drug; >97% eliminated by glomerular filtration within 24 hours. Minimal biliary/fecal elimination (<3%).
