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.
Osmotic diuretic; increases plasma osmolality, drawing water from extravascular to intravascular space, thereby reducing intracranial and intraocular pressure.
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.
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 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 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 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 excretion as unchanged drug; >97% eliminated by glomerular filtration within 24 hours. Minimal biliary/fecal elimination (<3%).
