Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mannitol is an osmotic diuretic that increases plasma osmolality, thereby drawing water from extravascular spaces into the plasma and reducing intracranial 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: 50-100 g (1-2 g/kg) as a 15-25% solution over 30-60 minutes. For cerebral edema: 0.25-1 g/kg IV every 4-6 hours. For oliguric acute kidney injury: test dose of 0.2 g/kg IV over 3-5 minutes; if urine output >50 mL/hr, administer 50-100 g as 15-20% solution over 2-6 hours.
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 elimination half-life approximately 0.5–1 hour in normal renal function; prolonged to 24–36 hours in anuria or severe renal impairment.
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% excreted unchanged in urine within 24 hours; minimal biliary/fecal elimination (<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%).
