Eligibility Criteria
Inclusion Criteria
- •Patients aged 60 - 75 years
- •Patients diagnosed with asthma (NIH, 2007) over six months ago
- •Patients maintaining monotherapy of low dose inhaled budesonide (pulmicort 400µg/day or ciclesonide 160 µg/day or fluticasone 250 µg/day) or combination of low dose inhaled budesonide and LABA (Seretide® 250 µg/day or Symbicort® 320 µg/day ) for over a month before the participation in this trial
- •Patients not reaching 'well controlled asthma status' with four-week monotherapy of low dose inhaled budesonide (Pulmicort 400 µg/day)
- •Patients who sufficiently listen to the purpose and content of this trial and the properties of investigational products and voluntarily agree with the participation to sign a written consent approved by IRB of Ajou University Medical Center before the participation in this trial
Exclusion Criteria

Arms & Interventions
Monotherapy of medium dose ICS
Intervention: Monotherapy of medium dose ICS
Combination of low ICS and montelukast
Intervention: Combination of low ICS and montelukast
Outcomes
Primary Outcomes
Rate of patients reaching "well controlled asthma status"
Time Frame: 12-weeks treatment
Rate of patients reaching "well controlled asthma status" after 12-week treatment : evaluating comprehensively frequency of day symptoms and night symptoms, limit of activities and use of rescue medicine based on GINA guideline for asthma management (GINA 2006) and PEF or FEV1(% predicted)
Secondary Outcomes
- Time to first well-controlled week(during the 12 weeks of treatment)
- Sub-group analysis of leukotrienes associated genotypes(visit 1)
- Biomarkers of inflammation(baseline(W1), W5, W9, W13, W17)
