title: Addition of montelukast versus double dose of inhaled budesonide in moderate persistent asthma.
abstract: BACKGROUND
  Although current guidelines suggest the use of inhaled corticosteroids as the first line therapy in persistent asthma, the concerns about high-dose corticosteroids may limit their usage. We aimed to investigate the efficacy of inhaled budesonide plus oral montelukast versus a double dose of inhaled budesonide.
  
  
  METHODS
  Thirty patients with moderate asthma took part in the study. Following a 2-week run in period, the patients were randomized into two groups to receive 400 microg/day of inhaled budesonide plus 10 mg/day of montelukast (BUD + M group) or 800 microg/day of inhaled budesonide (high BUD group). The patients were evaluated at 2-week intervals (during a total treatment period of 6 weeks) for symptom scores, asthma exacerbations, lung function, use of short-acting beta2 agonist, blood eosinophil counts and adverse events.
  
  
  RESULTS
  At the end of the study, morning and daytime symptom scores were significantly reduced within the groups. Although there was a significant decrease in the frequency of short-acting beta2 agonist use in the BUD + M group, the decrease in the high BUD group was not significant. During the study period, no patient in either group experienced an asthma exacerbation. Blood eosinophil levels significantly declined in both the BUD + M (0.87 +/- 0.31%) and high BUD groups (0.67 +/- 0.29%) as compared with baseline levels (BUD + M = 2.60 +/- 0.65%, high BUD group = 2.60 +/- 0.47%; P < 0.05).
  
  
  CONCLUSIONS
  Our results suggest that the addition of montelukast to low-dose inhaled budesonide is as effective as a double dose of inhaled budesonide in asthma control.
