MANNITOL 20% vs OSMITROL 20% IN WATER
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 extracellular fluid, thereby reducing intracranial pressure and promoting diuresis.
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.
Adult: 50-100 g intravenously as a 20% solution over 30-60 minutes. For cerebral edema: 0.25-1 g/kg IV over 30-60 minutes. For oliguric acute kidney injury: test dose 0.2 g/kg IV over 3-5 minutes.
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 elimination half-life 1.1–1.6 hours in normal renal function; prolonged to 18–36 hours in anuria/end-stage renal disease.
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; negligible biliary (<2%) or fecal elimination.
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.
