Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Increases plasma osmolality, drawing water from intracellular and interstitial spaces into the vascular compartment, thereby reducing intracranial pressure and intraocular pressure. Acts as an osmotic diuretic in the kidneys, increasing urine flow by inhibiting water reabsorption in the proximal tubule and loop of Henle.
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.
1-2 g/kg as a 15% solution intravenously over 30-60 minutes. Typical adult dose: 100-200 g (667-1333 mL of 15% solution) administered as a single dose for reduction of intracranial pressure or promotion of diuresis.
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 0.25-1.5 hours in normal renal function; prolonged to 24-36 hours in 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.
Primarily renal (90-100% as unchanged drug); negligible biliary/fecal elimination.
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%).
