ABSTRACT
Background:
This study aimed to describe the use of pressured metered dose inhalers (pMDI) and dry powder inhalers (DPI) in Spanish patients in terms of socio-demographic, clinical, and functional characteristics in patients with asthma or COPD on maintenance treatment with inhaled therapy.Methods:
A retrospective, descriptive, national, multicentre, and observational study using a database with 1.8 million patients from hospitals and primary care centers as a secondary information source.Results:
The sample included 24,102 subjects with asthma on maintenance therapy (26.0% with pMDI, 54.9% with DPI, and 19.0% with a combination of DPI + pMDI inhalers) and 12,858 subjects with COPD on maintenance therapy (26.1% with pMDI, 38.7% with DPI and 35.2% with a combination of pMDI + DPI inhalers, mostly extemporary triple therapy). In proportion, subjects ≥ 75 years old use more pMDI than DPI, while younger subjects (40-64 years old) use more DPI. An inhalation chamber was prescribed in 51.0% of asthma subjects and 47.2% of COPD subjects treated with pMDI. The use of an inhalation chamber increases with the degree of airflow limitation by disease and age. In subjects with comorbidities, pMDI inhaler use increased in those ≥75 years old for asthma and COPD subjects. Switching from pMDI to DPI and vice versa was relatively common 25.5% of asthma subjects and 21.9% of COPD subjects treated with pMDI had switched from DPI in the previous year. On the contrary, 14.1% and 11.7% of asthma and COPD patients treated with DPI had switched from pMDI the last year.Conclusions:
The use of pMDI or DPI can vary according to age, both in asthma and COPD. Switching from pMDI to DPI and vice versa is relatively common. Despite the availability of dual and triple therapy inhalers on the market, a considerable number of subjects were treated with multiple devices.
