ISMOTIC vs OSMITROL 5% 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 that increases plasma osmolality, drawing water from intracellular and interstitial spaces into the extracellular compartment, thereby reducing cerebral edema and intraocular pressure; also promotes diuresis by increasing renal tubular fluid osmolality.
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.
50-100 g intravenously as a 5% solution over 30-60 minutes; may repeat every 6-8 hours as needed. Maximum dose: 200 g in 24 hours.

4.5-6.0 hours in adults with normal renal function; prolonged in renal impairment (up to 24-48 hours in anuria)
Approximately 0.25-1.5 hours (15-90 minutes); prolonged in renal impairment or with mannitol accumulation (e.g., in anuria).
Renal: 90-95% unchanged; biliary/fecal: <5%
Primarily renal (90-100% unchanged in urine); negligible biliary or fecal elimination.
