The purpose of this study is to demonstrate whether subjects respond similarly to the Onset of Effect Questionnaire (OEQ) administered pre-dose versus post-dose, while receiving SYMBICORT® pMDI 80/4.5 μg x 2 actuations twice daily or budesonide HFA pMDI 80 μg x 2 actuations twice daily.

Primary Purpose: Treatment
Official Title: A Two-week, Randomised, Double-blind Study Assessing the Onset of Effect Questionnaire Administered Pre-dose Versus Post-dose in Adult Subjects (≥ 18 Years) With Mild to Moderate Asthma, Receiving SYMBICORT® pMDI 80/4.5 μg x 2 Actuations Twice Daily or Budesonide HFA pMDI 80 μg x 2 Act. Twice Daily

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • To determine whether subjects respond similarly to the Onset of Effect Questionnaire items 2 and 5 when administered post-dose versus pre-dose and does that difference favour a bronchodilator treatment group over a non-bronchodilator treatment group

Secondary Outcome Measures:
  • To determine if there is an association between the immediate physiological response to medication and the responses to OEQ items 2 and 5 and to determine what subjects mean when they say they feel their asthma maintenance medication 'working right away
