title: Indacaterol: a new once daily long-acting beta(2) adrenoceptor agonist.
abstract: BACKGROUND
  Indacaterol is a novel once daily long-acting beta agonist (LABA) developed for the treatment of chronic obstructive pulmonary disease (COPD) and asthma.
  
  
  OBJECTIVE
  This review summarizes preclinical and clinical data of indacaterol, including all data generated during the phase II trial program, and further discusses the outlook and potential of the drug in the future treatment of COPD and asthma.
  
  
  METHODS
  Clinical studies suggest that indacaterol produces rapid and sustained bronchodilation in COPD patients and asthmatics of different severities. Until now, clinical studies of up to 28 days' duration have been published that have confirmed the suitability of indacaterol for once daily dosing, along with a favorable overall safety and tolerability profile.
  
  
  CONCLUSIONS
  Indacaterol monotherapy has potential in COPD, where antiinflammatory treatment is not fully established and issues about a potential risk of LABA use causing excess mortality have not been raised. In addition, indacaterol represents an option for future combination therapies in both asthma and COPD. However, more data are required, particularly in COPD, to fully assess the therapeutic potential of indacaterol in improving symptoms, quality of life, exacerbation rates, disease progression, exercise capacity, and hyperinflation. The currently ongoing phase III clinical trial program will add knowledge in respect to many long-term efficacy outcomes and gather further safety and tolerability data in both asthma and COPD.
