Mannitol

Introduction

Mannitol is a type of sugar alcohol that is commonly used in medicine as a diuretic and osmotic agent. It helps reduce pressure and swelling in the brain, eyes, and kidneys by drawing excess fluid out of the body. Doctors often prescribe Mannitol for emergency situations like head injuries, glaucoma, and kidney conditions. Apart from medical uses, it is also used in laboratories and pharmaceutical preparations. Mannitol is available in different dosage forms and should be used under the supervision of a healthcare professional.

How Mannitol Works

Mannitol works as an osmotic diuretic by increasing the amount of water and salt excreted from the body through urine. It draws excess fluid from tissues like the brain and eyes into the blood, which is then filtered out by the kidneys. This process helps reduce pressure and swelling effectively.
