| Summary: | Inhaled corticosteroids are widely used in the treatment of chronic obstructive pulmonary disease (COPD). However, their use has been questioned for appropriate dose and a possible increased risk of pneumonia. Here, we reviewed patients with COPD who had received fluticasone–salmeterol combination treatment using data from a linked electronic medical record database. A total of 180 patients received salmeterol with 250 µg fluticasone propionate twice daily and 78 received salmeterol and 100 µg fluticasone propionate twice daily. In both groups, there was no difference in the improved forced expiratory volume in 1 second and COPD assessment test score and the proportion of patients with exacerbations. Although the incidence of common toxicity was approximately equal, that of pneumonia was much higher in the 250 µg group (8.9% vs 1.3%, P =.01). The beneficial effects of inhaled corticosteroids might be obtained at lower doses.
