Acceptance of the Accuhaler, a multidose powder inhaler, among asthmatic Patients: A comparison with the pressurized metered-dose inhaler

This study aimed to evaluate dry powder inhaler naive asthmatic patients' p erception and preference of the Accuhaler(TM), a multidose dry powder inhal er and the pressurized metered dose inhaler (pMDI). After the first instruc tion, 66.7% of 48 patients enrolled in the study could demonstrate the corr ect use of the Accuhaler(TM). When the patients were asked to compare the p MDI and the Accuhater(TM) after using the Accuhaler to administer salmetero l for 4 weeks, the Accuhaler(TM) scored significantly better than the pMDI for the following features: knowing how many doses are left, presence of an attached cover, taste, instruction for use, attractiveness, ease of use, e ase of holding, shape, and comfortable mouthpiece. The pMDI scored better t o the Accuhaler(TM) in terms of size. More patients preferred the Accuhater (TM) than the pMDI; the presence of a dose counter and perceived ease of us e were the main reasons cited for their preference for the Accuhaler(TM).
