Bronchiectasis is a long-term lung condition associated with bronchial dilatation, chronic inflammation and infection. Treatment is often empirical or extrapolated from other lung conditions, for example the use of inhaled therapies licensed for use in asthma or chronic obstructive pulmonary disease. Inhaled therapies, such as corticosteroids or long-acting bronchodilators (long-acting beta agonists or long-acting muscarinic antagonists), are commonly used in bronchiectasis despite scanty evidence on exacerbation reduction.
