Cough can be divided into the following cases: 1. If the cough is accompanied by a lot of phlegm, you can take drugs to reduce phlegm and stop coughing, such as amiloride and compound licorice tablets, etc. 2. If the patient has only a dry cough without phlegm, accompanied by a tickling throat, you can take antagonists of leukotriene receptors, such as montelukast, beta agonists, and theophylline drugs, etc. 3. If you go to the hospital for examination, the ratio of white blood cells as well as neutrophils is high If you go to the hospital and have a high percentage of white blood cells as well as neutrophils, high inflammatory indexes, and imaging of the chest suggesting inflammatory changes of respiratory tract infection, it suggests a bacterial infection. Antibiotics should be used to treat commonly used drugs such as cephalosporins, macrolides, and fluorinated quinolones.”
