Non-eosinophilic airway inflammation is actually relative to eosinophilic airway inflammation, which means that this airway inflammation is not caused by asthma or allergy, but mainly by the combination of other pathogens, such as bacteria, viruses, mycoplasma, chlamydia, rickettsia, etc. The treatment at this time is symptomatic and etiological. For pathogens, such as bacterial infections, one or two or more antibiotics can be chosen, such as penicillin, amoxicillin, cefoperazone, levofloxacin, clindamycin, roxithromycin, azithromycin, etc. In addition, for the presence of cough and sputum, nebulized inhalation treatment can be given, choosing budesonide nebulizer and chymotrypsin to get rid of sputum. When there is wheezing and shortness of breath, nebulizer inhalation that dilates the bronchi can be combined, such as salbutamol nebulizer, terbutaline nebulizer, ipratropium bromide nebulizer, etc.
