Chronic bronchitis does not have a definitive first choice of medication, it is treated primarily on the basis of the symptoms experienced by the patient, which need to be determined in conjunction with the appropriate symptoms. Chronic bronchitis is characterized by coughing, sputum, or wheezing. Drug treatment is mainly symptomatic. If there is cough, cough sputum, you can use aminobromine hydrochloride, bromhexine and other cough expectorant; if the main dry cough, you can use dextromethorphan and other cough suppressant; if there is wheezing and other symptoms, you can give bronchodilators such as aminophylline or inhalation of albuterol and other asthma. Respiratory infections often cause exacerbation of chronic bronchitis symptoms, and should be actively controlled. In case of bacterial infection, appropriate antibiotics such as levofloxacin, amoxicillin and cefuroxime can be selected empirically. Meanwhile, if the causative bacteria can be cultured, antibiotics can be selected according to the drug sensitivity test. It is recommended that patients with chronic bronchitis go to the relevant departments of the hospital in a timely manner, under the guidance of professional doctors, improve the relevant examinations, assess the patient’s condition and receive standardized treatment.
