Randomized Controlled Trial Multicenter Study Comparative StudyA randomised cross-over trial investigating the ease of use and preference of two dry powder inhalers in patients with asthma or chronic obstructive pulmonary disease.
The objective of this randomised, cross-over study was to compare a new single-dose dry powder inhaler (Elpenhaler (EH)), with a widely used, multi-dose dry powder inhaler (Diskus (DK)) on critical errors, patient preference, and satisfaction with the inhalers. ⋯ With DK fewer errors were made, more patients preferred DK over EH and patients were more satisfied with DK. This may enable DK to improve treatment outcomes more than EH.
