Pneumonia is a common infectious disease of the respiratory system. Patients with pneumonia can choose broad-spectrum antibiotics for treatment. In clinical practice, if there is no history of allergy, patients are advised to take oral antibiotics such as amoxicillin, cefdinir, moxifloxacin and azithromycin to control the infection. If there is no obvious effect after 3 days of treatment with one antibiotic, the medication can be adjusted promptly. If the patient’s clinical symptoms are obvious and the infection is heavy, it is still recommended to take sputum bacterial culture and drug sensitivity test specimens before using the medication, and choose a sensitive antibiotic to control the infection according to the results of the drug sensitivity test. For patients whose oral medication is not effective, further infusion therapy is also an option.
