Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Sorbitol and mannitol are sugar alcohols that act as osmotic diuretics. They are filtered by the glomerulus but not reabsorbed, increasing osmotic pressure in the tubular lumen, thereby reducing water reabsorption and promoting diuresis. They also increase intraocular pressure and decrease intracranial pressure by drawing water from tissues into the bloodstream.
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.
Osmotic diuretic; 50-100 g (as 25% solution) IV over 30-60 minutes, may repeat every 6-12 hours as needed; maximum 200 g/day.

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.
Terminal elimination half-life is approximately 4-6 hours; may be prolonged in renal impairment.
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%).
Primarily renal excretion as unchanged drug; >90% eliminated via urine within 24 hours.
