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 urinary output by raising the osmolarity of glomerular filtrate, thereby reducing tubular reabsorption of water and solutes. It also reduces cerebral edema by creating an osmotic gradient across the blood-brain barrier, drawing water from brain tissue into plasma.
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.
0.25-2 g/kg intravenously as a 10% solution over 30-60 minutes, typically 50-100 g every 6-8 hours.
