Mannitol Injection IP 25% w/v is a sterile, non-pyrogenic hyperosmotic solution used to reduce elevated intracranial and intraocular pressure. It is commonly indicated in the management of cerebral edema, glaucoma, and for promoting diuresis in acute renal failure or toxic substance elimination.
Mannitol acts as an osmotic diuretic. When administered intravenously, it increases the osmotic pressure of plasma, drawing water from tissues (including the brain and eyes) into the bloodstream. It also reaches the renal tubules where it inhibits reabsorption of water and electrolytes, thereby increasing urine output. This dual action relieves pressure and aids in detoxification through enhanced diuresis.
