Study summary

The study compares Buventol® Easyhaler® and Bufomix® Easyhaler® to the current standard treatment during methacholine challenge test. The trial will also provide inspiratory flow profile data for Easyhaler inhaler.

This trial is designed to provide a further evidence for the use of Easyhaler in diagnostic bronchial challenge tests and on the use of Easyhaler inhaler during obstructive event.

What researchers measure

Primary outcomes

  1. Forced expiratory volume in one second (FEV1)

    Mean change in FEV1 from post-diluent to FEV1 after the first dose of reliever.

    Time frame: 10 minutes

Secondary outcomes

  1. Number of subjects who recover from bronchoconstriction after first dose

    Proportion of the subjects who recover to FEV1 \> -10% compared to post-diluent FEV1 after first dose of reliever.

    Time frame: 10 minutes

  2. Forced expiratory volume in one second (FEV1)

    Relative recovery of FEV1 after the study treatment dosing when compared to post-diluent FEV1.

    Time frame: 10 minutes

  3. Number of subjects who recover from bronchoconstriction after second dose

    Proportions of subjects reaching FEV1 \> -10% of post-diluent value after second dose of reliever.

    Time frame: 20 minutes

Other outcomes

  1. Number of patients needing medical attention

    Proportion of subjects needing medical attention after study treatment

    Time frame: After study treatment administration until study completion (an average of 2.5 hours)

  2. Inhalation profile via Easyhaler

    Time-inspiratory flow -curve via Easyhaler measured with spirometer.

    Time frame: Before methacholine challenge and 10 minutes after the subject experiences FEV1 drop ≥ 20% compared to post-diluent spirometry
