Bronchitis in clinical practice, due to different inducing factors and the duration of the disease course, is classified into different types. Therefore, the duration of treatment for different types of bronchitis also varies. For acute bronchitis caused by acute bacterial infections, clinical treatment usually involves medication for infection, cough relief, expectoration, and asthma relief. It can be cured in about 1-2 weeks. However, in cases of chronic bronchitis, it is generally not possible to achieve a complete cure. It leads to a non-specific inflammatory change in the bronchi, causing patients to experience recurrent symptoms of coughing, phlegm, and asthma year-round, which are not easy to alleviate. The medications used clinically can only improve some aspects of the patients' quality of life, but not cure the condition.
