Purulent tonsillitis is a serious infectious disease clinically, mainly manifesting as severe pain in the pharyngeal area, general malaise in patients, and even symptoms such as chills and fever. Therefore, active treatment is required. Clinical treatment is mainly anti-infection treatment. Infusion primarily uses cephalosporin antibiotics such as ceftriaxone and cefazolin for treatment. To enhance the anti-infection effect and reduce the edema of the patient's throat mucosa, corticosteroid drugs such as dexamethasone or prednisolone are often used simultaneously in the infusion treatment.
