Clinical efficacy of Bufei Yishen and Qutan Tongluo Cream on the treatment of patients with stable chronic obstructive pulmonary disease

BYQTC significantly enhances the efficacy of conventional therapy in stable COPD patients, resulting in improvements in clinical symptoms, lung function, and overall quality of life. Notable enhancements were observed in FEV1%, 6MWT distance, and reductions in mMRC and CAT scores. Additionally, BYQTC treatment led to substantial decreases in IL-8 and MMP-9 levels, and reduced the incidence of acute exacerbations and rehospitalizations, demonstrating its superior therapeutic benefit compared to standard treatment.
