Abstract：Objective To investigate the clinical effect of Ambroxol Hydrochloride in the treatment of chronic bronchitis.Methods Sixty-eight patients with chronic bronchitis admitted to our hospital from August 2017 to July 2018 were selected as the research objects，they were randomly divided into control group and observation group by throwing sieve method，with 34 cases in each group.Patients in the control group were treated with routine drugs，while patients in the observation group were treated with Ambroxol Hydrochloride on the basis of the control group.The total effective rate of clinical treatment，the level of pulmonary function index and the disappearance time of symptoms were compared between the two groups.Results The total effective rate of clinical treatment in the observation group was 94.12%，which was significantly higher than 76.47%in the control group，the difference was significant（P＜0.05）.After treatment，the first second forced expiratory volume（FEV1），peak expiratory flow（PEF），FEV1/forced vital capacity（FVC）in the observation group were higher than those in the control group，the difference was significant（P＜0.05）.The disappearance time of each disease in the observation group was shorter than that in the control group，the difference was statistically significant（P＜0.05）.Conclusion Chronic bronchitis patients in the routine treatment at the same time，add Ambroxol Hydrochloride，can make faster recovery，can improve the level of pulmonary function indicators of patients，clinical application is worth promoting.
