Patients with bronchial asthma, if treated properly, can be cured. Although the pathogenesis of bronchial asthma is not very clear at present, it is currently believed that bronchial asthma is a chronic inflammatory disease of the airways involving multiple cells. This chronic inflammation leads to increased airway reactivity, manifesting as reversible airflow limitation. It is different from chronic bronchitis, which involves irreversible airflow limitation. Therefore, through proper treatment, the condition can be improved, controlled, and cured. Patients should regularly and properly use their medications, including inhaled corticosteroids such as budesonide, taken twice daily. It should be used for more than three months before any reduction in dosage can be considered. The medication can be stopped only if no asthma occurs for a year.
