In clinical practice, for patients with bronchitis and pneumonia caused by infection with Mycoplasma pneumoniae, macrolides, such as azithromycin, are generally preferred for treatment, but some people are not effective after taking them. The main common thing is that the infected Mycoplasma pneumoniae is not sensitive to the antibiotic, azithromycin, which produces resistance. Therefore, clinically, one can choose to take the patient’s respiratory secretions and do a drug sensitivity test for mycoplasma to clarify the sensitive antibiotic. For example, you can choose other drugs such as quinolones, levofloxacin, ciprofloxacin, gatifloxacin, lomefloxacin, etc. Other drugs of macrolides such as roxithromycin, methomycin, clarithromycin, etc. can also be chosen.
