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 tubular osmotic pressure, thereby inhibiting water reabsorption and promoting diuresis.
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.
0.25-1 g/kg intravenously over 30-60 minutes, repeated every 6-12 hours if needed.
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.

Terminal elimination half-life is 0.25–1.5 hours in normal renal function; prolonged to 4–6 hours with anuria or oliguria. Clinically, osmotic diuresis lasts as long as urine output sustains concentration.
Sorbitol: approximately 0.5-1 hour; mannitol: approximately 0.5-1.5 hours. In anuria, mannitol half-life may extend to 36 hours.
Primarily renal (90-100% unchanged) via glomerular filtration; <3% metabolized in liver; minimal biliary/fecal excretion.
Renal: >95% as unchanged sorbitol and mannitol; negligible biliary/fecal elimination.
