Background: Inhaled long‐acting β2‐agonists (LABA) are often poorly adhered to by elderly patients with chronic obstructive pulmonary disease (COPD). We hypothesized that older age and compromised cognitive function might contribute to poor adherence to inhaled medications among COPD patients, and that transdermally delivered medications could improve adherence, exercise tolerance and quality of life (QOL). Objective: To compare adherence and effects on health outcomes between transdermal and inhaled LABA. Methods: A total of 44 treatment‐naïve, elderly Japanese patients with moderate‐to‐severe COPD were treated with a transdermal tulobuterol patch (TP; 2 mg, once a day) or inhaled salmeterol (50 µg, twice a day) in a randomized crossover manner. The primary outcomes were adherence to the LABA medications and changes in QOL measured by the St George's Respiratory Questionnaire. Secondary outcomes were changes in 6‐min walk distance (6MWD) and spirometric values. Results: The overall adherence rate was 90.3 ± 1.6% for TP and 75.5 ± 2.9% for salmeterol ( P < 0.001). Adherence to salmeterol was correlated with age and Mini‐Mental State Examination (MMSE) score ( P < 0.05 and P < 0.01, respectively), although that to TP was relatively constant regardless of age and MMSE score. 6MWD and QOL were significantly improved from baseline after TP, but not after salmeterol treatment ( P < 0.05). Similar degrees of increase in spirometric values occurred after treatment with TP and salmeterol. Conclusions: Adherence levels were higher overall with TP than with inhaled salmeterol, and more stable across age groups and MMSE levels. TP might be a favorable treatment option for COPD patients with poor adherence to an inhaled LABA. Geriatr Gerontol Int 2013; 13: 398–404 .
