Compared to DPIs, pMDIs may be the preferential choice for patients with asthma.Īsthma dry powder inhaler inhaled corticosteroid and long-acting β-agonist inhaler device pressurized metered-dose inhaler.Ībe Y, Shibata Y, Igarashi A, et al. Although DPI prescription accounts for the predominant market share of combined ICS/LABA in Japan, patients preferred a pMDI device to a DPI device. With regard to patient preferences, 57.4% preferred the Adoair ® Aerosol and 35.3% preferred the Adoair ® Diskus ®, as determined via the comparative evaluation questionnaire. There were no significant differences between quality-of-life scores, FeNO, spirometry test results and forced oscillation results. Sixty-eight subjects were included in the final analysis. ![]() Questionnaires, exhaled nitric oxide (FeNO) tests and pulmonary function tests were administered after the use of each device for 8 weeks, and the results derived from each device were compared. A prospective, randomized, crossover, comparative study in adult outpatients with asthma was conducted using salmeterol/fluticasone propionate combination (SFC) 50 μg/250 μg, one inhalation of Adoair ® 250 Diskus ® twice daily or two inhalations of Adoair ® 125 Aerosol twice daily, for 8 weeks. In the current study, the beneficial effects and side effects associated with DPIs and pMDIs were compared, and the question of which device should be recommended for asthma patients was investigated. There are few reports comparing the effects of the two devices, and it is unknown which should be recommended for asthma patients with given sets of characteristics. Two main types of devices are used to facilitate the administration of inhaled corticosteroid (ICS) and long-acting β-agonist (LABA) in combination, dry powder inhalers (DPIs) and pressurized metered-dose inhalers (pMDIs).
