Rationale
The majority of patients have poor inhaler technique, with the ability to coordinate actuation with inhalation being one of the most common errors.1,2
Despite this, many adults do not use spacers for the delivery of inhaler medication, especially while on the go.
Potential reasons for not using spacers include portability and appearance
The aim of this usability/preference study was to understand patient perceptions of two portable spacer devices compared to the metered dose inhaler (MDI) when used alone.
Conclusion
The prototype AeroChamber2go* spacer device was preferred by patients compared to the A2A† spacer and provides a good option for patients currently using the Metered Dose Inhaler without a spacer while on-the-go.
