Abstract
Objective To observe the efficacy of inhaled tiotropium bromide combined with budesonide/formoterol on reducing the frequency of acute episodes of symptom exacerbation and improving lung function,health status in chronic obstructive pulmonary disease (COPD). Methods Eighty-six patients with COPD were divided into 3 groups, combination group[29 cases, inhaled budesonide/formoterol (160 μg/4.5 μg, twice one day ) and tiotropium bromide ( 18 μg, once one day)], budesonide/formoterol group( 29 cases, 160 μg/4.5 μg, twice one day) and tiotropium bromide group(28 cases, 18 μg, once one day). The treatment continued for 3 months. Results Lung function, symptoms and health status improved obviously in three groups. The forced expiratory volume in one second (FEV1) of combination group after treatment was (1.24±0.18) L , which was improved by 11.7% compared with before treatment. It was significantly higher than that in budesenide/formoterol group and fiotropium bromide group (P 0.05 ). Conclusions Combination treatment produces better control of symptoms and lung function and has no greater risk of sideeffects, compared with the treatment of budesonide/formoterol alone and tiotropium bromide alone. The combination treatment should be considered for patients with COPD. Key words: Pulmonary,chronic obstructive; Budesonide; Tiotropium bromide; Formoterol; Respiratory function tests
