MANNITOL 5% 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 the osmolarity of the glomerular filtrate, reducing tubular reabsorption of water and solutes. It also draws water from intracellular spaces into the extracellular fluid, 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.
50-100 g intravenously over 30-60 minutes for initial dose in acute renal failure or cerebral edema; maintenance dose 25-50 g every 6-8 hours based on serum osmolality and urine output.
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: 1–2 hours (adults with normal renal function); prolonged to 24–48 hours in 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% as unchanged drug via glomerular filtration; negligible biliary 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.
