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 extracellular fluid, thereby reducing intracranial pressure and promoting diuresis.
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.
Adult: 50-100 g intravenously as a 20% solution over 30-60 minutes. For cerebral edema: 0.25-1 g/kg IV over 30-60 minutes. For oliguric acute kidney injury: test dose 0.2 g/kg IV over 3-5 minutes.
0.25-1 g/kg intravenously over 30-60 minutes, repeated every 6-12 hours if needed.

Terminal elimination half-life 1.1–1.6 hours in normal renal function; prolonged to 18–36 hours in anuria/end-stage renal disease.
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.
Renal, >90% unchanged by glomerular filtration; negligible biliary (<2%) or fecal elimination.
Primarily renal (90-100% unchanged) via glomerular filtration; <3% metabolized in liver; minimal biliary/fecal excretion.
