Clinical Study on the Treatment of Stable Bronchiectasis With Bailing Capsules Combined With Guben Kechuan Granules
The goal of this clinical trial is to learn if Bailing Capsules in combination Guben Kechuan Granules works to treat stable bronchiectasis in adults.It will also learn about the safety of Bailing Capsules in combination Guben Kechuan Granules The main questions it aims to answer are: Does Bailing Capsules in combination Guben Kechuan Granules lower the number of acute exacerbation in patients with stable bronchiectasis? The safety of the combination of Bailing Capsules and Guben Kechuan Granules ? Researchers will compare the combination of Bailing Capsules and Guben Kechuan Granules to standard Western medical treatment to see if them works to treat stable bronchiectasis. Participants will: Take Bailing Capsules orally (four capsules each time, three times a day) and Guben Kechuan Granules ( three times a day, 1 bag each time )on the basis of standard Western medical treatment or only standard Western medical treatment for 24 weeks Visit the clinic for checkups and tests on 4, 12, 24, 48 weeks Keep a diary of their symptoms
