Most patients with bronchitis do not need to take antibiotic drugs. However, if there is a basis for pathogenic bacterial infection, appropriate antibiotic treatment can be selected based on the doctor’s experience or sputum culture results. Bronchitis is an acute inflammation of the mucous membranes of the trachea-bronchus caused by biological, physical or chemical stimuli or allergies, which may be manifested by coughing, coughing up sputum, and occasionally with blood in the sputum and other symptoms. Treatment is generally symptomatic. If coughing without sputum, dextromethorphan and pentoxyverine can be used to suppress coughing. If coughing, sputum and not easy to cough out, can use aminobromine hydrochloride, bromhexine and other cough and sputum. When there are bacterial infections such as Haemophilus influenzae, Streptococcus pneumoniae, Catamorium, etc., penicillins such as amoxicillin, cephalosporins such as cefixime, or quinolones such as levofloxacin, etc., can be used to treat anti-infections. If infected by Mycoplasma, Chlamydia pneumoniae, etc., macrolides such as azithromycin and other drugs can be preferred for anti-infection treatment. Bronchitis patients should follow the doctor’s instructions for medication, conducive to the recovery of the disease, do not self-medication.
