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 vascular compartment, thereby reducing intracranial pressure and intraocular pressure. Acts as an osmotic diuretic in the kidneys, increasing urine flow by inhibiting water reabsorption in the proximal tubule and loop of Henle.
Osmotic diuretic; increases plasma osmolality, drawing water from extravascular to intravascular space, thereby reducing intracranial and intraocular pressure.
1-2 g/kg as a 15% solution intravenously over 30-60 minutes. Typical adult dose: 100-200 g (667-1333 mL of 15% solution) administered as a single dose for reduction of intracranial pressure or promotion of diuresis.
IV infusion of 50-200 g over 30-60 minutes as a 15% solution; typical adult dose is 1.5-2 g/kg every 6-8 hours.

Terminal elimination half-life approximately 0.25-1.5 hours in normal renal function; prolonged to 24-36 hours in renal impairment.
Terminal elimination half-life is approximately 0.25–1.5 hours in patients with normal renal function; prolonged to 24–36 hours in anuria or severe renal impairment.
Primarily renal (90-100% as unchanged drug); negligible biliary/fecal elimination.
Primarily renal excretion as unchanged drug; >97% eliminated by glomerular filtration within 24 hours. Minimal biliary/fecal elimination (<3%).
