Bronchitol is a medication designed to manage and treat certain lung conditions, particularly cystic fibrosis, a genetic disorder that affects the lungs and other organs. It is an inhaled dry powder form of mannitol, a type of sugar alcohol that works by drawing water into the airways. This action helps to thin the mucus, making it easier to clear from the lungs and improving breathing function. Bronchitol is typically used as part of a broader treatment regimen for cystic fibrosis patients who have not responded adequately to other therapies. It is important for patients to be properly trained in the correct use of Bronchitol to ensure its effectiveness and to minimize potential side effects.
