MANNITOL 25% vs OSMITROL 20% IN WATER IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mannitol is an osmotic diuretic that increases plasma osmolarity, drawing water from intracellular and interstitial spaces into the intravascular compartment. In the kidney, it is filtered but not reabsorbed, increasing tubular fluid osmolarity and promoting water excretion. It also reduces intracranial and intraocular pressure by creating an osmotic gradient.
Osmotic diuretic that increases plasma osmolality, drawing water from intracellular spaces into extracellular fluid and increasing renal tubular osmotic pressure, thereby inhibiting water reabsorption and promoting diuresis.
1-2 g/kg (4-8 mL/kg) intravenously as a 25% solution over 30-60 minutes; may repeat every 6-8 hours as needed.
0.25-1 g/kg intravenously over 30-60 minutes, repeated every 6-12 hours if needed.

Terminal elimination half-life: 0.25–1.7 hours; prolonged in renal impairment.
Terminal elimination half-life is 0.25–1.5 hours in normal renal function; prolonged to 4–6 hours with anuria or oliguria. Clinically, osmotic diuresis lasts as long as urine output sustains concentration.
Renal: >90% unchanged by glomerular filtration; biliary/fecal: <5%.
Primarily renal (90-100% unchanged) via glomerular filtration; <3% metabolized in liver; minimal biliary/fecal excretion.
