Bronchitis with cephalosporin or azithromycin, depending on the situation of the patient infected with the pathogenic bacteria to decide, as long as the symptom which drug efficacy is very good, if not symptomatic, then the best drugs are useless. For example, if a patient with bronchitis is infected with Streptococcus pneumoniae, it is better to choose oral cephalosporins of the first and second generation. But if the patient is infected with Mycoplasma pneumoniae, it would be better to use azithromycin orally at this time. Therefore, for patients with different flora infections, it is most useful to choose the corresponding antibiotic treatment, which can be selected by the patient’s sputum bacterial culture and drug sensitivity test results, and the one with the highest sensitivity is the one with the best treatment effect.
