Clinical trials of tulobuterol patch in the treatment of acute exacerbation of chronic obstructive pulmonary disease in the elderly / 中华老年医学杂志

ABSTRACT

Objective To evaluate the efficacy and safety of tulobuterol patch in the treatment of acute exacerbation of chronic obstructive pulmonary disease(AECOPD) in the elderly. Methods Totally 165 elderly patients with moderate to severe AECOPD were divided into trial group and control group randomly.83 patients of trial group were treated with tulobuterol patch,2 mg once a day,and fluticasone inhalation 250 μg twice a day; 82 patients of control group were treated with inhalation of salmeterol/fluticasone 250 μg/50 μg twice a day.Basic therapy was the same in two groups. Results After 10-14 days' treatment,forced expiratory volume in one second(FEV1),peak expiratory flow (PEF),6-min walking distance and symptom scores were ( 1.30 ± 0.31 ) L,(245.3 ± 56.1 ) L/min,(263.0±53.2)m,(33.2±12.1)scores in trial group,and (1.21±0.23)L,(213.9±58.4) L/min,(230.0±45.6)m,(37.8± 14.5) scores in control group,respectively.The lung function,6 minute walk distancc and symptom score were improved (t=2.120,3.521,4.279,2.212,all P＜0.05).The frequencies of rescue medication,waking-up suffocating at night and the days of hospital stay were deceased significantly in trial group as compared with control group[(2.5 ± 0.6) time/d,( 1.8 ± 0.5)time/week,(12.9±1.6)dvs.(2.90.8) time/d,(2.2±0.7) time/week,(14.1±1.8) d,t=3.610,4.219,4.524,all P＜0.05].The incidence of adverse reactions was not significant difference between two groups[8 cases(9.6％)vs.7 cases(8.5％),P＞0.05] and the adverse reactions were mild.Conclusions Tulobuterol patch is a newly formulated,effective and safe medication for the treatment of acute exacerbation of AECOPD.
