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 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.
0.25-1 g/kg intravenously over 30-60 minutes, repeated every 6-12 hours if needed.
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.

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.
Terminal elimination half-life is approximately 4-6 hours; may be prolonged in renal impairment.
Primarily renal (90-100% unchanged) via glomerular filtration; <3% metabolized in liver; minimal biliary/fecal excretion.
Primarily renal excretion as unchanged drug; >90% eliminated via urine within 24 hours.
