Study 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.

Primary Outcome

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.

Interventions
