Pioneer generally refers to cephalosporin antibiotics. If the pneumonia cough is caused by bacteria that are sensitive to cephalosporin antibiotics, cephalosporin antibiotics can be taken to treat the infection. If the pneumonia cough is caused by other pathogens, cephalosporin antibiotics are less effective. Pneumonia can be caused by bacterial, mycoplasma, chlamydia, and viral infections, and can present with high fever, cough, sputum, and other symptoms, and its treatment is mainly based on anti-infective therapy. The sensitive bacteria of cephalosporin antibiotics mainly include Staphylococcus aureus, Streptococcus pyogenes, S. pneumoniae, etc. If the infection is caused by the above mentioned bacteria, cephalosporin antibiotics can be taken for anti-infection treatment. If the cough is caused by other pathogenic bacteria such as mycoplasma, it can be treated with macrolide antibiotics such as azithromycin; if the cough is caused by influenza virus, it can be treated with antiviral drugs such as oseltamivir. If there is phlegm in the cough and it is not easy to cough it up, you can give aminoglutethimide hydrochloride, bromhexine and other drugs to stop the cough and resolve the phlegm, and if necessary, you can give acetylcysteine nebulization to dispel the phlegm. Pneumonia cough is recommended to identify the causative pathogens, and then to be targeted drug treatment, in order to achieve the best therapeutic effect.
