MANNITOL 25% vs OSMITROL 15% IN WATER
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; increases plasma osmolality, drawing water from extravascular to intravascular space, thereby reducing intracranial and intraocular pressure.
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.
IV infusion of 50-200 g over 30-60 minutes as a 15% solution; typical adult dose is 1.5-2 g/kg every 6-8 hours.

Terminal elimination half-life: 0.25–1.7 hours; prolonged in renal impairment.
Terminal elimination half-life is approximately 0.25–1.5 hours in patients with normal renal function; prolonged to 24–36 hours in anuria or severe renal impairment.
Renal: >90% unchanged by glomerular filtration; biliary/fecal: <5%.
Primarily renal excretion as unchanged drug; >97% eliminated by glomerular filtration within 24 hours. Minimal biliary/fecal elimination (<3%).
