MANNITOL 5% vs OSMITROL 5% IN WATER IN PLASTIC CONTAINER
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. It is filtered by glomerulus and not reabsorbed, leading to increased urinary output and reduction of intracranial/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.
Intravenous infusion. Usual adult dose: 50-100 grams (500-1000 mL of 5% solution) administered over 30-60 minutes. Frequency: every 6-12 hours as needed for cerebral edema or reduction of intraocular pressure.

Terminal: 0.25–1.5 h (prolonged in renal impairment); clinical context: accumulates in renal failure, monitor serum osmolarity and renal function
The terminal elimination half-life is approximately 1.5 to 2 hours in adults with normal renal function. This can be prolonged to 6-12 hours in patients with renal impairment, requiring dose adjustment.
Renal: 90% unchanged; biliary/fecal: negligible (<2%)
Mannitol is excreted primarily by the kidneys via glomerular filtration, with approximately 80% of an administered dose appearing unchanged in urine within 3 hours. Less than 10% undergoes tubular reabsorption; negligible biliary or fecal elimination (<1%).
