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.
Mannitol is an osmotic diuretic that increases plasma osmolality, drawing water from intracellular spaces into the extracellular fluid and vasculature, thereby reducing intracranial and intraocular pressure. It also increases renal tubular osmotic pressure, inhibiting water reabsorption and promoting diuresis.
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.
Intravenous infusion of 50-100 g (as a 5% solution) over 2-6 hours, typically 500-1000 mL, for osmotic diuresis; or for reduction of intracranial pressure, 1-2 g/kg IV over 30-60 minutes as a 15-25% solution.
