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 spaces into the extracellular fluid and bloodstream, thereby reducing cerebral edema and promoting diuresis. Dextrose provides a source of calories and may help prevent hypoglycemia.
Increases plasma osmolality, drawing water from tissues into the bloodstream, thereby reducing intracranial pressure and cerebral edema.
Adult: 50-100 g (500-1000 mL of 10% solution) intravenously over 1-2 hours, repeated as needed every 6-12 hours. Individualize based on urine output and serum osmolality.
Initial: 0.25–1 g/kg (25–100 mL of 10% solution) IV over 30–60 minutes. May repeat every 6–12 hours if needed. Typical adult dose: 50–100 g IV. Maximum: 2 g/kg per dose.

Terminal elimination half-life of mannitol is approximately 1.5-2 hours in patients with normal renal function. Clinically, duration of osmotic diuresis parallels half-life; in renal impairment, half-life may extend to 24-36 hours, increasing risk of fluid overload and electrolyte disturbances.
Terminal half-life approximately 1.5 hours in normal renal function; prolonged in renal impairment (up to 36 hours in anuria).
Primarily renal excretion: Mannitol is filtered by glomeruli and not reabsorbed, excreted unchanged in urine (approximately 80-90% within 24 hours). Biliary/fecal elimination is negligible (<5%). Dextrose is metabolized to CO2 and water; any excess is excreted renally as glucose if threshold exceeded.
Primarily renal; >90% excreted unchanged in urine via glomerular filtration; <5% biliary/fecal.
