Mannitol is an osmotic diuretic. It is administered intravenously to help create more urine. This is important in cases of intoxication, when a person needs to excrete toxic materials. Mannitol can also help when a person is suffering from acute renal failure, as the increased urine both speeds up the excretion of toxic materials and helps stop the kidneys from shutting down entirely. Mannitol is also given to help reduce swelling inside a person's eye or around their brain.

Mannitol is a sugary substance that kills tumor cells without destroying healthy tissue. The agent may be delivered to the tumor site via a catheter and may be used alone or in conjunction with surgery.
