The main symptoms of acute bronchitis are cough and sputum, and the treatment is mainly symptomatic. If the cough is dry and without sputum, it is usually enough to stop the cough and dilate the bronchial tubes, which is usually treated with fenagan cough syrup and meperidine. If the cough and phlegm are more frequent, in addition to cough suppression treatment, phlegm must also be dissolved, and you can apply Ambroxol or phlegm dissolving tablets to dilute the phlegm and facilitate coughing out. Compound licorice tablets have the effect of relieving cough and dissolving phlegm. There are also some Chinese patent medicines such as Chuanbei loquat, lung power cough, etc., which also have better effect on acute bronchitis. Nebulized inhalation is also a treatment for acute bronchitis. If the cough is coughing and coughing up sputum, you can apply cortisone; if it is accompanied by allergic or irritating cough, you can add Pulmicort to deal with it. In addition, the original disease must be treated. If it is a bacterial infection, antibiotics must be applied; if it is a viral infection, such as influenza A or epidemic influenza B, oseltamivir antiviral treatment can also be applied.
