Treatment of asthma includes identifying and reducing exposure to risk factors, medication, and immunotherapy. 1. Identify and reduce exposure to risk factors: some patients can find allergens or risk factors, the most effective way to treat asthma is to avoid exposure to these risk factors. 2. Medication: (1) Glucocorticosteroids: they are the most effective drugs for controlling asthma, inhaled hormones such as beclomethasone, oral hormones such as prednisone, and intravenous hormones such as hydrocortisone. (2) Beta agonists: such as salbutamol, terbutaline, etc., are the drugs of choice for the treatment of acute asthma attacks. (3) Leukotriene modulators: e.g. montelukast, zalukast, etc. (4) Theophyllines: e.g. aminophylline, slow-release theophylline, etc. Their main adverse effects include nausea, vomiting, arrhythmia, decreased blood pressure and polyuria. (5) Anticholinergics: such as ipratropium bromide, which can diastole bronchial tubes and reduce mucus secretion. 3. Immunotherapy: (1) Specific immunotherapy: it is suitable for patients who have clear allergens and cannot control their asthma well after avoiding contact with allergens as well as standardized drug therapy. (2) non-specific immunotherapy: such as injections of BCG and its derivatives, transfer factors, vaccines, etc., have some secondary efficacy. Asthma patients should not self-medication, should go to the hospital in time, under the guidance of the doctor standardized treatment.
