  • Title: [Therapeutic approach to the distal airways in asthma].
    Author: de Diego Damiá A, Vega Chicote JM.
    Journal: Arch Bronconeumol; 2011 Apr; 47 Suppl 2():27-31. PubMed ID: 21640282.
    Abstract:
    Bronchial asthma is a chronic inflammatory disease that affects both the large-caliber airways and the smaller-caliber bronchioles. In the last few years, a major therapeutic advance has been made with the development of new systems of inhalation solutions, which produce extra-fine particles, achieving better lung deposition throughout the airways and reducing oropharyngeal deposition. These formulations have improved the effectiveness of bronchodilation and particularly the antiinflammatory effect. The use of long-acting b2-adrenergic steroids in extra-fine formulation, whether alone or in combinations of fixed doses, improves drug distribution throughout the bronchial tree, enhancing the therapeutic effect with lower doses of drugs. Leukotriene receptor antagonists have shown their effect on the small airways in asthmatic patients, both in studies of pulmonary resistance and pulmonary volumes and in imaging studies.
