ISMOTIC vs OSMITROL 15% IN WATER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Isosmotic solution of mannitol; increases plasma osmolality, drawing water from tissues into the vasculature and reducing intracranial/intraocular pressure via osmotic diuresis.
Osmotic diuretic; increases plasma osmolality, drawing water from extravascular to intravascular space, thereby reducing intracranial and intraocular pressure.
1-2 g orally every 6-8 hours, maximum 8 g/day; or 1-2 g intravenously over 5-10 minutes every 6-8 hours, maximum 8 g/day.
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.

4.5-6.0 hours in adults with normal renal function; prolonged in renal impairment (up to 24-48 hours in anuria)
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: 90-95% unchanged; biliary/fecal: <5%
Primarily renal excretion as unchanged drug; >97% eliminated by glomerular filtration within 24 hours. Minimal biliary/fecal elimination (<3%).
