The phenomenon of constant cough and shortness of breath is likely to be chronic bronchitis or cough variant asthma, and it is necessary to go to the hospital for chest CT and bronchodilator test. If chest CT shows that there is chronic bronchitis, cough and phlegm treatment as well as anti-inflammatory treatment should be given in the acute stage, and sensitive antibiotics can be chosen for anti-inflammatory treatment according to the results of sputum culture. Additionally, aminoglutethimide hydrochloride or aminoglutethimide oral solution can be used to resolve sputum. For more severe asthma, nebulized inhalation of budesonide and terbutaline can be used, and aminophylline can also be used for asthma calming. If there is a positive bronchodilator test, it is cough and shortness of breath caused by cough variant asthma, and then long-term nebulized inhalation of bronchodilators and glucocorticosteroids are needed, such as nebulized inhalation of budesonide and terbutaline. In the case of adults or children over 10 years of age, inhalation of Cymbalta can be used directly to relieve the symptoms of cough and shortness of breath.
