OSMITROL 20% IN WATER vs SORBITOL-MANNITOL IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Sorbitol and mannitol are osmotic diuretics. They increase osmotic pressure in the glomerular filtrate, reducing water reabsorption and promoting diuresis. Mannitol also decreases intracranial and intraocular pressure by creating an osmotic gradient that draws water from tissues into the vasculature.
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.
Intravenous infusion of 50 mL of a 25% sorbitol-25% mannitol solution administered over 10–20 minutes; may repeat once after 6–8 hours if needed.

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.
Sorbitol: approximately 0.5-1 hour; mannitol: approximately 0.5-1.5 hours. In anuria, mannitol half-life may extend to 36 hours.
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.
Renal: >95% as unchanged sorbitol and mannitol; negligible biliary/fecal elimination.
