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 osmotic diuretics. They increase osmotic pressure in the glomerular filtrate, reducing water reabsorption and promoting diuresis. Mannitol also decreases intracranial and intraocular pressure by creating an osmotic gradient that draws water from tissues into the vasculature.
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.
Intravenous infusion of 50 mL of a 25% sorbitol-25% mannitol solution administered over 10–20 minutes; may repeat once after 6–8 hours if needed.

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.
Sorbitol: approximately 0.5-1 hour; mannitol: approximately 0.5-1.5 hours. In anuria, mannitol half-life may extend to 36 hours.
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%).
Renal: >95% as unchanged sorbitol and mannitol; negligible biliary/fecal elimination.
