Therapeutic effect of tiotropium bromide powder inhalation in patients with stable bronchiectasis / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To observe the therapeutic effect of tiotropium bromide powder inhalation on stable bronchiectasis.</p><p><b>METHODS</b>Twenty-two patients with stable bronchiectasis received inhalation of totropium bromide powder at the daily dose of 18 microg, and on days 1 and 28, the patients were examined for forced expiratory volume in one second (FEVl), predicted value [FEVl(%)], forced expiratory volume (FEV), and FEVl/FVC. The symptom score and BODE index were also recorded.</p><p><b>RESULTS</b>After 1 month of inhalation therapy, the FEV1% of the patients showed a moderate increase but the increment was not statistically significant (t=-1.875, P>0.05); the symptom score and BODE index decreased significantly after the therapy (t=7.091, P<0.001; t=2.982, P<0.05).</p><p><b>CONCLUSION</b>Long-term inhalation of tiotropium bromide powder can improve the clinical symptoms and BODE index and enhance the exercise tolerance and quality of life of the patients with bronchiectasis.</p>
