What researchers measure

Primary outcomes

  1. Difference in peak flow between active and placebo limbs by the morning after randomization

    Time frame: 24 hours maximum

Secondary outcomes

  1. Time (hours) to achieve PEF and FEV greater than or equal to 75% best achieved in the last 12 months with greater than or equal to 25% diurnal variation

    Time frame: 24 hours maximum

  2. Time to discharge from hospital

  3. PEF, FEV and FVC (as % best/predicted) the morning following admission and at 4 week clinic follow up

  4. Proportion of days (post discharge until follow up) with a PEFR of less than or equal to 75%, and less than or equal to 50% best predicted

  5. Proportion of days (post discharge until follow up) with a PEFR variability of greater than or equal to 25%

  6. Residual volume as % predicted and RV/TLC% and FEF50 and FEF75 at 4 week out patient visit

  7. requirement for further medical intervention / increases in treatment following discharge

  8. Evaluation of quality of life over the four week out patient follow up period and expressed preference to continue on study medication

  9. Evaluation of economic costs and savings from the additional treatment
