The treatment of dyspnea cannot be generalized because the causes are different. If the dyspnea is caused by bronchial asthma, it is usually seen in acute attacks of bronchial asthma, and short-acting β2 agonists, such as salbutamol sulfate and terbutaline sulfate tablets, can be used in emergency. After the disease is controlled, oral hormone plus β2 agonists such as salmeterol tetrasone powder inhaler, fluticasone propionate, budesonide inhalation aerosol, formoterol, etc. can be given. If caused by interstitial lung disease, generally, hormones or cytotoxic drugs and, if necessary, antifibrotic drugs such as pirfenidone and nidanib can be used for antifibrotic treatment. If it is caused by acute exacerbation of COPD, it is necessary to target the causative factors that cause acute exacerbation, such as viral, bacterial, mycoplasma, chlamydia and other pathogenic microbial infections, and choose different drugs for these pathogenic microorganisms. If it is a viral infection, antiviral treatment can be given, and if it is a bacterial infection, antibiotic anti-infective treatment can be given. In the case of pathogenic microorganisms such as mycoplasma and chlamydia infections, macrolides can be given, and in the case of adults over 18 years of age, quinolone antibiotics can also be given for treatment.
