Bronchial asthma treatment mainly includes reducing exposure to risk factors, controlling and relieving drugs and immunotherapy. 1. Reducing exposure to risk factors: some patients have allergens such as dust mites, pollen, fish and shrimp, as well as asthma triggering factors such as air pollution and exercise, etc. Reducing exposure to risk factors by avoiding exposure to allergens and avoiding strenuous exercise can effectively prevent and treat asthma. 2. Drug therapy: mainly includes relieving drugs and controlling drugs. Relievers include short-acting β2 agonists such as salbutamol, short-acting inhaled anticholinergics such as ipratropium bromide, aminophylline, and hydrocortisone succinate, etc., which are mostly used in acute exacerbations and are used on an as-needed basis. Controlled medications include inhaled glucocorticosteroids and hormones such as budesonide, leukotriene modulators such as zalustat, long-acting β2 agonists such as the extended-release theophylline salmeterol, and sodium cromoglycate, which are used for chronic persistence and for long periods of time. 3. Immunotherapy: specific immunotherapy, i.e., desensitization therapy, can increase the patient’s tolerance to allergens. Non-specific immunotherapy mainly includes injection of BCG vaccine, transfer factor, etc., which has a certain auxiliary therapeutic effect. Treatment options should be selected according to the severity of the disease and the patient’s personal situation, and it is recommended that the patient consult a doctor in a timely manner, follow the doctor’s instructions to choose the appropriate treatment plan, and drugs should be used under the guidance of a physician.
