Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mannitol is an osmotic diuretic that increases plasma osmolality, drawing water from intracellular compartments into extracellular fluid. In the kidneys, it is freely filtered at the glomerulus but minimally reabsorbed, increasing tubular fluid osmolality and reducing water reabsorption, thereby promoting diuresis. It also reduces cerebral edema by creating an osmotic gradient that draws water from brain tissue into plasma.
Osmotically active agent that increases plasma osmolality, drawing water from intracellular and interstitial spaces into the vascular compartment, thereby reducing cerebral edema and intraocular pressure.
Intravenous: 50-100 g (250-500 mL of 20% solution) over 30-60 minutes; may repeat every 6-8 hours as needed. For cerebral edema: 1-2 g/kg IV over 30-60 minutes.
1.5-2 g/kg intravenous infusion over 30-60 minutes every 6-8 hours as needed for reduction of intracranial pressure or cerebral edema.

Terminal elimination half-life: 0.25–1.7 hours in normal renal function; prolonged in renal impairment.
Terminal half-life: 0.25–1.5 hours (15–90 minutes) in normal renal function; prolonged to 24–36 hours in anuria or severe renal impairment.
Renal: >90% as unchanged drug. Biliary/fecal: negligible.
Renal: >90% unchanged by glomerular filtration; minimal tubular reabsorption or secretion. <10% metabolized in liver (negligible).
