Primary Outcome Measures:
  • Difference in peak flow between active and placebo limbs by the morning after randomization [ Time Frame: 24 hours maximum ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • 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 ] [ Designated as safety issue: No ]
  • Time to discharge from hospital [ Designated as safety issue: No ]
  • PEF, FEV and FVC (as % best/predicted) the morning following admission and at 4 week clinic follow up [ Designated as safety issue: No ]
  • 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 [ Designated as safety issue: No ]
  • Proportion of days (post discharge until follow up) with a PEFR variability of greater than or equal to 25% [ Designated as safety issue: No ]
  • Residual volume as % predicted and RV/TLC% and FEF50 and FEF75 at 4 week out patient visit [ Designated as safety issue: No ]
  • requirement for further medical intervention / increases in treatment following discharge [ Designated as safety issue: No ]
  • Evaluation of quality of life over the four week out patient follow up period and expressed preference to continue on study medication [ Designated as safety issue: No ]
  • Evaluation of economic costs and savings from the additional treatment [ Designated as safety issue: No ]
