Ability of using different dry powder inhalers during COPD exacerbations.

BACKGROUND: Guidelines suggest that patients hospitalized for acute COPD exacerbations (AECOPD) are treated with short acting bronchodilators. Long acting bronchodilators, offer longer symptom relief but since they are usually administered via Dry Powder Inhalers (DPIs) it is considered that during AECOPD patients would not be able to achieve appropriate inspiratory flow (IF) to receive appropriate drug doses. The aim of the present study was to evaluate whether patients admitted to the hospital for AECOPD, are able to achieve the necessary IF using different DPIs.

METHODS: IF was measured daily in patients admitted for AECOPD with a portable IF meter (In-Check Oral inhaler assessment kit), containing a series of adapters that simulate the resistance of 4 DPIs [Turbuhaler (T), Breezhaler/Aerolizer (B/F), Discus (A/A/D) and Handinhaler (HH)]. Dyspnea, spirometry and arterial blood gases were also recorded daily.

RESULTS: 44 consecutive patients were included in the study. The majority of patients were able to achieve an IF over 30 L/min with all four device resistances. This minimum required IF was achieved in 90.9%, 100%, 95.5% and 81.8% of patients on admission and in 100%, 100%, 97.7%, and 95.5% of patients on discharge for T, B/F, A/A/D and HH respectively. No functional characteristic was able to predict the achievement of this minimum necessary IF.

CONCLUSION: Most patients hospitalized for AECOPD, are able to receive treatment with long acting bronchodilators administered via DPIs. The possible beneficial effects of such an intervention should be tested in further studies.
