MANNITOL 15% IN PLASTIC CONTAINER vs OSMITROL 20% IN WATER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mannitol is an osmotic diuretic that increases plasma osmolality, thereby drawing water from extravascular spaces into the plasma and reducing intracranial pressure. It also increases renal tubular osmotic pressure, inhibiting water reabsorption and promoting diuresis.

Intravenous: 50-100 g (1-2 g/kg) as a 15-25% solution over 30-60 minutes. For cerebral edema: 0.25-1 g/kg IV every 4-6 hours. For oliguric acute kidney injury: test dose of 0.2 g/kg IV over 3-5 minutes; if urine output >50 mL/hr, administer 50-100 g as 15-20% solution over 2-6 hours.
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 approximately 0.5–1 hour 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% excreted unchanged in urine within 24 hours; minimal biliary/fecal elimination (<2%).
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.
