Keep this leaflet with the medicine. You may need to read it again. What Bronchitol is used for Your medicine is used to treat Cystic Fibrosis. Bronchitol is inhaled into the lungs to relieve the symptoms of cystic fibrosis. It does this by helping to clear mucus from the lungs. Bronchitol contains the active ingredient mannitol. It works by increasing the amount of water on the surface of your airways and in your mucus. This helps your lungs to clear mucus more easily. It also helps improve the condition of your lungs and your breathing. As a result you may get a ‘productive cough’, which also helps to remove mucus from your lungs. Your doctor may have prescribed Bronchitol for another reason. Ask your doctor if you have any questions about why Bronchitol has been prescribed for you. There is no evidence that Bronchitol is addictive. This medicine is available only with a doctor’s prescription. Before you take Bronchitol Before you are started on Bronchitol, your doctor will check whether your airways are too sensitive to mannitol. This is done by giving your first (initiation) dose of Bronchitol under strictly controlled Leer el documento completo
Bronchitol Australian PI 30 October 2012 Page 1 of 11 PRODUCT INFORMATION BRONCHITOL MANNITOL POWDER FOR INHALATION NAME OF THE MEDICINE Mannitol. Also known as D-mannitol. The empirical formula is C 6 H 14 O 6 . Molecular weight is 182.2 CAS number: 69-65-8. Structural Formula: DESCRIPTION Mannitol is a hexahydric alcohol. The powder is a white or almost white, crystalline powder of free- flowing granules. Mannitol is freely soluble in water, and very slightly soluble in alcohol. Mannitol shows polymorphism. Mannitol is the only ingredient in the contents of the hard gelatin capsules. PHARMACOLOGY _PHARMACODYNAMICS _ Bronchitol contains mannitol that has been spray dried to achieve a respirable form. The spray dried mannitol is to be delivered by use of a specific inhaler device. The inhalation of mannitol is intended to improve lung hygiene by correcting the impaired mucociliary clearance that is characteristic of cystic fibrosis. While the exact mechanism of action is unknown, inhaled mannitol may change the viscoelastic properties of mucus, increase the hydration of the periciliary fluid layer and contribute to increased mucociliary and cough clearance of the retained secretions. _PHARMACOKINETICS _ Absorption: In a study of 18 healthy male adult volunteers, using an Aridol inhaler, the absolute bioavailability of mannitol powder for inhalation by comparison to mannitol administered intravenously was 0.59 ± 0.15. The rate and extent of absorption of mannitol after inhaled administration was very similar to that observed after oral administration. The T max after inhaled administration was 1.5 ± 0.5 hours. In a study of 9 cystic fibrosis patients (6 adults, 3 adolescents), using 400 mg inhaled mannitol as a single dose (Day 1) then twice a day Leer el documento completo
