Triple therapy with salmeterol/fluticasone propionate 50/250 plus tiotropium bromide improve lung function versus individual treatments in moderate-to-severe Japanese COPD patients: a randomized controlled trial – Evaluation of Airway sGaw after treatment with tripLE

Purpose Triple therapy using salmeterol/fluticasone propionate (FP) and tiotropium bromide is commonly used to treat chronic obstructive pulmonary disease (COPD), but sparse efficacy data exist in COPD patients with fewer symptoms and with a lower dose of inhaled corticosteroid in Japanese patients. The effects of of salmeterol/fluticasone propionate 50/250 μg (SFC250) twice daily plus tiotropium 18 μg (TIO) once daily and individual treatments on lung function were compared.
