Bronchiectasis is a disease state defined by localized, irreversible dilation of part of the bronchial tree caused by destruction of the muscle and elastic tissue.  It is classified as an obstructive lung disease, along with emphysema, bronchitis, asthma, and cystic fibrosis.  Involved bronchi are dilated, inflamed, and easily collapsible, resulting in airflow obstruction and impaired clearance of secretions.  Bronchiectasis is associated with a wide range of disorders, but it usually results from bacterial infections, such as infections caused by the Staphylococcus or Klebsiella species or Bordatella pertussis.

Treatment of bronchiectasis includes controlling infections and bronchial secretions, relieving airway obstructions, removal of affected portions of lung by surgical removal or artery embolization and preventing complications. This includes the prolonged usage of antibiotics to prevent detrimental infections, as well as eliminating accumulated fluid with postural drainage and chest physiotherapy. Surgery may also be used to treat localized bronchiectasis, removing obstructions that could cause progression of the disease.

Inhaled steroid therapy that is consistently adhered to can reduce sputum production and decrease airway constriction over a period of time, and help prevent progression of bronchiectasis. One commonly used therapy is beclometasone dipropionate, which is also used in asthma treatment.[20] Use of inhalers such as albuterol (salbutamol), fluticasone (Flovent/Flixotide) and ipratropium (Atrovent) may help reduce likelihood of infection by clearing the airways and decreasing inflammation.

Although not approved for use in any country, Mannitol dry inhalation powder, under the name Bronchitol, has been granted orphan drug status by the FDA for use in patients with bronchiectasis and with cystic fibrosis.

Combination therapies, long acting bronchodilators and inhaled corticosteroids such as Symbicort and Advair Diskus are also commonly used inhaled medicines which has in many cases been effective in clearing the airways, reducing sputum and reducing inflammation.
