MANNITOL 20% 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, drawing water from intracellular compartments into extracellular fluid. In the kidneys, it is freely filtered at the glomerulus but minimally reabsorbed, increasing tubular fluid osmolality and reducing water reabsorption, thereby promoting diuresis. It also reduces cerebral edema by creating an osmotic gradient that draws water from brain tissue into plasma.
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.
Intravenous: 50-100 g (250-500 mL of 20% solution) over 30-60 minutes; may repeat every 6-8 hours as needed. For cerebral edema: 1-2 g/kg IV over 30-60 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: 0.25–1.7 hours in normal renal function; prolonged in 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% as unchanged drug. Biliary/fecal: 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.
