Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Osmotically active agent that increases plasma osmolality, drawing water from intracellular and interstitial spaces into the vascular compartment, thereby reducing cerebral edema and intraocular pressure.
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.
1.5-2 g/kg intravenous infusion over 30-60 minutes every 6-8 hours as needed for reduction of intracranial pressure or cerebral edema.
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 half-life: 0.25–1.5 hours (15–90 minutes) 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% unchanged by glomerular filtration; minimal tubular reabsorption or secretion. <10% metabolized in liver (negligible).
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%).
