Mannitol is also known by the chemical name D-mannitol [1]. It is a sugar alcohol commonly used as a diuretic and an osmotic agent [1, 2].
Why is Mannitol Used Medically?
Mannitol serves multiple medical purposes, primarily due to its osmotic properties [2]. It is used to reduce intracranial pressure and cerebral edema in patients with brain injuries or tumors [3]. It also helps to decrease intraocular pressure in cases of glaucoma [2]. Additionally, mannitol can be employed to promote urinary excretion of certain toxins and in the management of acute kidney injury [2].
How Does Mannitol Work?
As an osmotic diuretic, mannitol works by increasing the osmolarity of the glomerular filtrate in the kidneys [2]. This process draws water from the body's tissues into the renal tubules, leading to increased urine production and removal of excess fluid [2, 4]. When used to reduce swelling in the brain, mannitol increases the osmolarity of the blood, drawing fluid out of swollen brain cells and into the bloodstream [3].
What Are the Potential Side Effects of Mannitol?
Patients may experience side effects from mannitol treatment. These can include dehydration, electrolyte imbalances (such as hyponatremia or hypernatremia), headache, and nausea [1, 2]. In some cases, it may also cause dizziness, blurred vision, or allergic reactions [1].
Are There Other Sugar Alcohols Like Mannitol?
Yes, other sugar alcohols exist and share some similar properties with mannitol. Common examples include sorbitol, xylitol, and erythritol [5]. These compounds are often used as sweeteners in sugar-free products and have varying caloric values and metabolic pathways [5].
