Osmitrol is a medication used to treat conditions like edema and high pressure inside the eye. This medication is also known by other names, such as sorbitol and mannitol. These synonyms are used interchangeably with osmitrol depending on the brand or manufacturer. Mannitol is commonly used in intravenous drips to reduce pressure inside the brain and prevent swelling. Sorbitol, on the other hand, is a natural sugar alcohol found in fruits and vegetables. It is used as a sweetener in various products and also works as a laxative. Thus, osmitrol, mannitol, and sorbitol all have different applications and are used to treat a range of different conditions.
