title: The impact of budesonide and other inhaled corticosteroid therapies in the management of asthma in children and adults.
abstract: BACKGROUND
  Since the recognition that asthma is characterized by extensive inflammation of the airways, the use of inhaled corticosteroids (ICSs) as controller therapy has become central to successful disease management. As the prevalence of asthma increases worldwide, there is concern about increasing numbers of patients with untreated or undertreated asthma, which may lead to deterioration in disease control, with direct effects on morbidity and mortality rates. The costs attributed to asthma translate into a considerable economic burden, from the direct costs of medical treatment to the costs incurred through lost work or school days. International treatment guidelines currently recommend early intervention with ICS therapy to improve lung function and disease control.
  
  
  OBJECTIVE
  This article reviews the role of therapy with ICSs, particularly budesonide, in improving the management of asthma in patients of all ages and in reducing the economic and social burdens of this disease.
  
  
  RESULTS
  Randomized, controlled clinical studies confirm the efficacy of early intervention with ICSs in patients with mild persistent asthma. Regular use of an ICS can reduce the number of exacerbations and hospitalizations in patients of all ages and with all disease severities.
  
  
  CONCLUSIONS
  Budesonide has a well-established efficacy and safety profile. Its once-daily dosing may contribute to improved adherence and cost-effectiveness.
