Patient's question:
Friends always have a persistent cough. They have used a lot of antibiotics and medications, but none have shown improvement. They have also taken many drugs, but the cough still hasn't gone away. After a thorough examination at a nearby hospital, it was determined to be medication-induced asthma. They want to consult about what are the common misconceptions in the treatment of medication-induced asthma?Doctor's answer:
The mechanism of corticosteroid treatment for asthma includes:First, anti-inflammatory effects. Bronchial asthma is a chronic airway inflammatory disease involving multiple inflammatory cells. Corticosteroids can reduce inflammation, alleviate airway inflammation, thereby reducing asthma symptoms.
Second, anti-allergic reactions. Bronchial asthma is related to allergic reactions, and acute attacks are closely associated with exposure to allergens (such as pollen, dust mites, odors, cold air, etc.). Allergens react with the body's antibodies, leading to antigen-antibody binding and the production of allergic reactions, resulting in airway hyperresponsiveness. Corticosteroids can effectively relieve allergic reactions.
Third, muscle relaxation and bronchodilation.
