How does mannitol inhalation work?

Inhaled mannitol is used for thinning and clearing mucus that becomes thick and adheres to the bronchial passage in people with pulmonary conditions such as cystic fibrosis. Mannitol inhalation is also used for diagnostic purposes to assess airway sensitivity to stimuli.

The precise mechanism by which mannitol thins the mucus is not clear. Mannitol is an osmotic agent and it is thought to work by drawing water from the lung cells into the airway, which rehydrates the mucus, loosens it, and facilitates its clearance from the lungs.
