MANNITOL 15% vs OSMITROL 5% IN WATER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Increases plasma osmolality, drawing water from intracellular and interstitial spaces into the vascular compartment, thereby reducing intracranial pressure and intraocular pressure. Acts as an osmotic diuretic in the kidneys, increasing urine flow by inhibiting water reabsorption in the proximal tubule and loop of Henle.
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/kg as a 15% solution intravenously over 30-60 minutes. Typical adult dose: 100-200 g (667-1333 mL of 15% solution) administered as a single dose for reduction of intracranial pressure or promotion of diuresis.
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.

Terminal elimination half-life approximately 0.25-1.5 hours in normal renal function; prolonged to 24-36 hours in renal impairment.
Approximately 0.25-1.5 hours (15-90 minutes); prolonged in renal impairment or with mannitol accumulation (e.g., in anuria).
Primarily renal (90-100% as unchanged drug); negligible biliary/fecal elimination.
Primarily renal (90-100% unchanged in urine); negligible biliary or fecal elimination.
