[LAMA/LABA fixed dose combination for treatment of COPD].

Several new fixed-dose combination bronchodilators have been launched in the world, and 3 different types are now available in Japan. Assessing their efficacy relative to each other has not been performed yet. In the present manuscript, characteristics of glycopyrronium/indacaterol, umeclidinium/vilanterol and tiotropium/olodaterol were reviewed. In particular, changes in trough and peak forced expiratory volume in 1 second (FEV1), St George's Respiratory Questionnaire (SGRQ) total scores, and transitional dyspnea index (TDI) focal scores were reviewed in these bronchodilators.
