title: Evaluation of combination long-acting beta-2 agonists and inhaled glucocorticosteroids for treatment of asthma.
abstract: BACKGROUND
  Treating asthma with a combination of inhaled corticosteroid and a long-acting beta-2-agonist is often preferred when asthma is not controlled when using a low-medium dose of an inhaled corticosteroid.
  
  
  OBJECTIVE
  To review the pharmacology, efficacy and safety of inhalers containing combinations of long-acting bronchodilators and inhaled corticosteroids to treat moderate-to-severe, persistent asthma.
  
  
  METHODS
  Using a list of keywords, we conducted a PubMed search of the literature. Data provided by the manufacturer were also reviewed.
  
  
  RESULTS
  Fluticasone propionate with salmeterol and budesonide with formoterol are both well tolerated, have equal clinical efficacy and have recent data affirming their safe use in diverse patient populations.
  
  
  CONCLUSIONS
  Combination inhalers improve asthma control in patients previously uncontrolled on inhaled corticosteroids.
