Objective:To analyze the clinical efficacy and safety of amoxicillin and clavulanate potassium in the treatment of chil-dren with suppurative tonsillitis. Methods:Totally 263 children with suppurative tonsillitis from March 2011 to September 2013 in pe-diatrics were randomly divided into two groups, the control group had 130 cases and the treatment group had 133 cases. All the patients were given conventional treatment, meanwhile, the control group was with intravenous infusion of azithromycin, and the treatment group was orally given amoxicillin and clavulanate potassium dispersible tablets. The clinical efficacy, clinical symptom disappearance time and the incidence of adverse reactions of the two groups were observed. Results:After the treatment, the control group were cured with the total effective rate of 83. 8%, and the treatment group were healed with the total effective rate of 90. 2%. The difference wasn't sig-nificant (P>0. 05). Orally used amoxicillin and clavulanate potassium was more economic and convenient, which could reduce the drug-resistance as well. There was no significant difference in the effects on fever, purulent and the white blood cell between the two groups, and no significant adverse reactions showed in both groups. Conclusion:Orally used amoxicillin and clavulanate potassium ex-hibits obvious therapeutic effect on infantile suppurative tonsillitis, which can effectively improve the clinical symptoms without obvious adverse reactions, and it is worthy of clinical use.
