Brief Summary:
This study is being carried out to see if budesonide with HFA is effective, safe and well tolerated compared with budesonide CFC. Budesonide HFA has been already given in other research studies, in both healthy volunteers and subjects with asthma.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. PC 20 Methacholine (Provocative Concentration of Methacholine Causing 20 % Fall in FEV1(Forced Expiratory Volume) [ Time Frame: Baseline and week 2 ]

    Provocative concentration of methacholine is that causing a 20% fall in FEV1. The methacholine challenge test entailed the patient inhaling from an aerosol containing doubling concentrations of methacholine over a period of 2 minutes until FEV1 had been reduced by 20%.

    The ratio of Methacholine concentration measured at 2 weeks to that at Baseline.



Secondary Outcome Measures :
  1. Peak Exploratory Flow (PEF) [ Time Frame: Baseline to week 2 recorded daily ]
    Change in PEF at Week 2 from baseline, mean over all days in run-in and all dasy in treatment period, with baseline as covariate.

  2. FEV1 (Forced Expiratory Volume in 1 Second) [ Time Frame: Baseline to week 2 ]
    FEV1 change from baseline

  3. FEF 25-75 (Forced Expiratory Flow 25-75) [ Time Frame: Baseline and week 2 ]
    FEF 25-75- Forced expiratory flow over the middle one half of the FVC. The results are expressed as the change from baseline

  4. eNO (Exhaled Nitrogen Oxide) [ Time Frame: baseline and week 2 ]
    eNO ratio of baseline

  5. Asthma Symptom Score Morning [ Time Frame: 2 weeks ]
    Asthma Symptom score recorded daily in the morning: Scale: 0-3. 0 = None; no asthma symptoms. 1 = Mild symptoms; aware of asthma symptoms but easily tolerated. 2 = Moderate symptoms; asthma causing enough discomfort to cause problems with normal activities (or with sleep). 3 =Severe symptoms; unable to do normal activities. The average of means for values recorded daily in the morning is presented.

  6. Asthma Symptom Score Evening [ Time Frame: 2 weeks ]
    Asthma Symptom score recorded daily in the evening: Scale: 0-3. 0 = None; no asthma symptoms. 1 = Mild symptoms; aware of asthma symptoms but easily tolerated. 2 = Moderate symptoms; asthma causing enough discomfort to cause problems with normal activities (or with sleep). 3 =Severe symptoms; unable to do normal activities. The average of means for values recorded daily in the evening is presented.

  7. Asthma Symptom Score Total [ Time Frame: 2 weeks ]
    Asthma Symptom score recoded daily, Total. Scale: 0 - 3. 0 = None; no asthma symptoms. 1 = Mild symptoms; aware of asthma symptoms but easily tolerated. 2 = Moderate symptoms; asthma causing enough discomfort to cause problems with normal activities (or with sleep). 3 =Severe symptoms; unable to do normal activities. The average of means for values recorded daily is presented.

  8. Rescue Medication Morning [ Time Frame: 2 weeks ]
    The average of means for inhalations of rescue medication in the morning is presented.

  9. Rescue Medication Evening [ Time Frame: 2 weeks ]
    The average of means for inhalations of rescue medication in the evening is presented.

  10. Rescue Medication Total [ Time Frame: 2 weeks ]
    The average of means for inhalations of rescue medication in morning and evening combined over a 24 hour period is presented.

  11. Peak Exploratory Flow (PEF) Morning [ Time Frame: 2 weeks ]
    Peak Exploratory Flow (PEF) recorded daily in the morning
