Mannitol is a sugar alcohol used as an osmotic diuretic. It is administered intravenously to reduce intracranial pressure and cerebral edema [1]. It works by drawing water out of cells, including brain cells, thus reducing swelling [1][2].
What is mannitol used for in medicine?
Mannitol is primarily used to treat increased intracranial pressure, which can be caused by brain tumors, head injuries, or other neurological conditions [1][3]. It is also used to promote urine flow in cases of kidney failure or to reduce intraocular pressure in patients with glaucoma [1][3].
How does mannitol work to reduce swelling?
Mannitol is poorly absorbed by the kidneys and remains in the bloodstream, creating an osmotic gradient. This gradient pulls water from tissues, such as the brain, into the bloodstream, thereby reducing edema and pressure [1][2]. When filtered by the kidneys, it inhibits sodium and chloride reabsorption, leading to increased urine output [1].
What are the potential side effects of mannitol?
Common side effects of mannitol include headache, nausea, vomiting, and dizziness [1]. More serious side effects can include fluid and electrolyte imbalances, such as dehydration, hypernatremia, and kidney damage [1][3]. Allergic reactions are also possible [1].
How is mannitol administered?
Mannitol is administered intravenously as an infusion [1]. The dosage and rate of administration depend on the patient's condition and medical needs [3].
Are there any alternatives to mannitol for reducing intracranial pressure?
Other treatments for reducing intracranial pressure include hypertonic saline, corticosteroids, and surgical interventions [4]. The choice of treatment depends on the underlying cause and severity of the condition [4].
