Moxifloxacin belongs to the quinolone class of broad-spectrum antibiotics for the treatment of pneumonia, and the course of treatment is usually about one week for pneumonia caused by common bacterial infections. It has a good bactericidal effect against both gram-positive and gram-negative bacteria. Depending on the severity of the disease, the medication can be given orally or intravenously, and the blood count should be reviewed at any time. After a week of medication, the chest X-ray can be reviewed, and attention should also be paid to symptomatic treatment, such as cough, phlegm, fever, a light diet, and appropriate bed rest.
