Hypertonic saline is one of the most frequently used hypertonic solutions in critical care, particularly for managing conditions such as severe symptomatic hyponatremia and elevated intracranial pressure. Unlike normal saline, this concentrated solution draws water out of cells and into the bloodstream through osmosis.

According to pharmaceutical experts, excipients are crucial for creating palatable tablets, and mannitol stands out as the most commonly used base for chewable tablets due to its excellent sensory properties. This article explores the properties of mannitol and compares it with other common excipients used in chewable formulations.

As a potent osmotic diuretic, mannitol is used in critical care to reduce swelling in the brain or eyes, but its primary action can cause a major adverse effect: significant shifts in the body's fluid and electrolyte balance. This can lead to serious complications if not carefully monitored and managed by healthcare professionals.

According to a Cochrane review of mannitol for acute traumatic brain injury, excessive or prolonged administration may cause mannitol to pass into the brain, where it might contribute to increased intracranial pressure. This finding offers a complex answer to the question: does mannitol increase intracranial pressure under specific, medically significant circumstances?

Intracranial hypertension, a sustained pressure above 20 mmHg, is a life-threatening emergency often seen after traumatic brain injury, and its presence significantly increases the risk of death [1.2.2]. So, in these critical moments, **what does hypertonic saline do to the brain?**

Mannitol was one of the first osmotic diuretics developed and is a versatile medication with a unique mechanism of action. What is the drug mannitol used for? It is primarily administered to address medical conditions involving excess fluid and pressure, particularly within the brain and eyes, by creating an osmotic gradient.

Brain swelling, a potentially life-threatening condition, occurs in response to many injuries, tumors, and infections. Understanding **what medication is used to reduce brain swelling** is critical for managing increased intracranial pressure and preventing severe neurological damage.

Hyperosmolar therapy is a core component of medical management for patients with acute intracranial hypertension. A foundational discovery in 1919 demonstrated that intravenous hyperosmolar solutions could significantly reduce intracranial pressure (ICP) and brain volume. What is hyperosmolar therapy? It is a life-saving strategy that uses highly concentrated solutions to create an osmotic gradient, drawing excess fluid from the brain to alleviate swelling.

In the United States, about 33% of children with severe traumatic brain injury receive hypertonic saline and 40% receive mannitol as part of osmotic therapy to manage brain swelling. So, **what is osmotic therapy?** It is a critical medical intervention that uses osmotically active substances to reduce fluid volume in the brain.
