Addition of a spacer device as an alternative in treatment with a metered inhaler.
The effects of 50 + 50 + 100 + 200 micrograms of fenoterol, inhaled from a conventional metered dose inhaler and a metered dose inhaler with an attached spacer device, a tube extension provided with a valve, the so-called aerochamber, respectively, were evaluated in a cumulative dose response study. There were no significant difference in the effect on the lung function or the side-effects following inhalation from the metered dose inhaler with or without an aerochamber.
