Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Osmotic diuretic that increases plasma osmolality, drawing water from intracellular spaces into extracellular fluid and increasing renal tubular osmotic pressure, which inhibits water reabsorption and promotes diuresis.
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.
1-2 g/kg (5-10 mL/kg of 20% solution) intravenously over 30-60 minutes for reduction of intracranial pressure; may repeat every 6-8 hours. For preoperative bowel preparation, 100-200 mL (20% solution) orally.

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.
0.25–1.5 hours (15–90 minutes) in patients with normal renal function. In oliguric or anuric patients, half-life is markedly prolonged, up to 36 hours, due to reduced clearance.
Renal: >90% unchanged by glomerular filtration; minimal tubular reabsorption or secretion. <10% metabolized in liver (negligible).
Primarily renal excretion as unchanged drug. Over 90% of administered dose is excreted unchanged in urine within 24 hours. Less than 5% is metabolized in the liver; negligible biliary/fecal elimination.
