A Cochrane review [Abstract] 1 included 84 studies. Few studies could be combined to assess a specific outcome for a given delivery device comparison. There were no differences between a standard CFC containing pMDI and any other device for most outcomes. Regular use of HFA-pMDI containing salbutamol reduces the requirement for short courses of oral corticosteroids (3 trials, 519 patients: RR 0.67, 95% CI 0.49 to 0.91). However, the total number of exacerbations was unchanged (3 trials, 1271 patients: RR 1.0, 95% CI 0.75 to 1.33).
