the purpose in this study was performed to elucidate the effects of combined treatment with tiotropium and olodaterol on DLH following hyperventilation.
Efficacy
Confirmatory
Explanatory
Phase IV
The primary outcome was defined as decrease in inspiratory capacity (IC) from rest by metronome-paced incremental hyperventilation(MPIH), which is an index of dynamic lung hyperinflation(DLH). after 8 weeks with treatment.
The secondary outcomes were COPD assessment test (CAT), FEV1, and 6-minute walking distance (6MWD). In addition to, as in previous studies, we investigated whether there are correlations between changes by treatment in DLH and exercise tolerance or dyspnea on exercise after 8weeks with treatment.

Treatment
Medicine |
Treatment was on the day after completion of the baseline examination, and consisted of administration of tiotropium/olodaterol 5/5 micro grum inhalation solution (2.5/2.5 microgram per actuation) by soft-mist inhaler. Patients were instructed to inhale two puffs from the inhaler, once a day, in the morning.
The combination of LAMA and LABA used consisted of Spiolt and Respimat, respectively (Nippon Boehringer Ingelheim Co., Ltd., Tokyo, Japan), which contained 2.5 microgram of tiotropium and 2.5 microgram of olodaterol per puff, respectively.

Male and Female
All patients suffered from smoking-related COPD without alpha 1 antitrypsin deficiency, and those with a smoking history of 10 pack-year or more including current smoker were selected for this study. In addition, as a substitute for LAMA and LABA during the washout period, patients who responded to symptoms with short-acting treatment were selected as eligible for inclusion. After receiving a thorough explanation of the study, patients who provided written consent were enrolled in the study
Patients with dysuria due to prostate hypertrophy, glaucoma, severe heart failure, exacerbation and/or respiratory infection within 3 months, prior history of lung surgery, severe heart disease, or impairment or difficulty in walking due to motor or cognitive dysfunction were excluded. Exacerbation history criteria was defined as an acute worsening of respiratory symptoms that result in additional therapy.

Partially published
Five of the 38 registered patients dropped out of the study. The reasons for dropping out were hospitalization due to gastrointestinal disorder, discontinuation of hospital visits for unknown reasons, refusal to undergo examination after treatment, hospitalization due to exacerbation of respiratory diseases, and did not meet the criteria of COPD after registration into the study in one patient each. All results were not trough values. Because.
Characteristics of patients and comparison of lung functions before and after treatment
The study population included patients with mild to severe disease as determined by classification of airflow limitation severity using %FEV1, 60% of all subjects were moderate disease status. FEV1, %FEV1, and FEV1/FVC (forced vital capacity) ratio were significantly higher after in comparison to before treatment , while CAT was lower after treatment.
Comparison of dynamic lung hyperinflation following metronome-paced incremental hyperventilation (MPIH) and 6MWT before and after treatment
-IC20, -IC30, and -IC40 were significantly decreased after treatment. IC20, IC30, and IC40 increased significantly after treatment. In addition, deltaIC was significantly decreased after treatment. The 6MWD was significantly increased after treatment.

Correlation of changes in DLH, FEV1, exercise tolerance, and dyspnea with treatment
There were not significant correlations between changes in each IC, FEV1, 6MWD, and BSmax with treatment.
