Ease-of-use preference for the ELLIPTA® dry powder inhaler over a commonly used single-dose capsule dry powder inhaler by inhalation device-naive Japanese volunteers aged 40 years or older.

ABSTRACT:

Background

In patients receiving inhaled medication, dissatisfaction with and difficulty in using the inhaler can affect treatment adherence. The incidence of handling errors is typically higher in the elderly than in younger people. The aim of the study was to assess inhaler preference for and handling errors with the ELLIPTA® dry powder inhaler (DPI), (GSK), compared with the established BREEZHALER™, a single-dose capsule DPI (Novartis), in inhalation device-naïve Japanese volunteers aged ≥40 years.

Methods
