Clinical Study on Shiwei Longdanhua Capsule Combined with Western Medicine for Treatment of Acute Exacerbation of Chronic Obstructive Pulmonary Disease / 中国中医药信息杂志

ABSTRACT

Objective To observe the clinical efficacy of Shiwei Longdanhua Capsule combined with western medicine on patients with mild acute exacerbation of chronic obstructive pulmonary disease (COPD) with phlegm-heat obstructing lung syndrome. Methods Totally 192 cases of COPD with mild acute exacerbation (phlegm-heat obstructing lung syndrome) were recruited. They were randomly divided into the treatment group (96 cases) and the control group (96 cases). Patients in the control group were treated in line with the regular Western treatment, while patients in the treatment group were additionally treated by Shiwei Longdanhua Capsule. After 10-day treatment, the changes of TCM syndrome score, symptom integral and the lung function before and after treatment were compared. Results After treatment, 14 patients withdrew from the treatment group and 15 patients withdrew from the control group. The total efficiency rate of TCM syndrome was 80.49% (66/82) in the treatment group, while it was 56.79% (46/81) in the control group, with statistical difference between the two groups (P<0.05). The severity and frequency of cough and expectoration of the treatment group were better than the control group (P<0.05). The breathing symptom and pulmonary function of patients in the two groups improved, with similar efficacy. Conclusion The efficiency of Shiwei Longdanhua Capsule combined with Western medicine in the treatment of acute exacerbation of COPD is superior to that of simple Western medicine treatment, especially in terms of relieving cough and expectoration.
