title: Once-daily inhaled corticosteroids for the treatment of asthma.
abstract: OBJECTIVE
  Inhaled corticosteroids (ICS) are the mainstay of asthma therapy. Although compliance to this type of medication is often suboptimal and once-daily dosing can help to improve adherence to the treatment, the clinical implications of such a mode of administration should be determined.
  
  
  RESULTS
  This review summarizes the recent studies on comparative efficacy of once-versus twice-daily administration of ICS, in light of previous reports.
  
  
  CONCLUSIONS
  Although twice-daily administration of ICS is often better to optimize asthma parameters, in many patients, asthma can be sufficiently controlled by a once-daily regimen of most ICS. An increased frequency of dosing seems preferable if asthma becomes uncontrolled or is severe, although this requires further study. A therapeutic trial should, however, be done to ensure that asthma control is adequate. Comparative long-term effects of such a strategy on inflammatory and remodeling parameters remain to be determined, as does the proportion of patients who can adequately control their asthma with once-daily administration of the various ICS available.
