Mannitol is a type of sugar alcohol commonly used in medicine for its diuretic properties. It is often administered intravenously to increase urine production, which can help to reduce fluid buildup in the body and lower pressure within the skull.

In medical practice, Mannitol is frequently employed to treat conditions such as cerebral edema (swelling of the brain), increased intracranial pressure, and acute kidney failure. By drawing water into the kidneys and promoting urine output, Mannitol helps to remove excess fluid from the body and alleviate pressure on vital organs.
