    Author: Bégué P, Garabedian N, Quinet B, Baron S.

    Abstract:
    Cefixime is a new oral cephalosporin antibiotic, with broad-spectrum of activity, near than of third generation cephalosporin, especially against betelactamase producers bacteria. Cefixime has been assayed with microbiological method in tonsils of 21 children (mean age 59 months). Tonsillectomy was performed 5 hours after a third dose of 4 mg/kg cefixime. Plasma levels were evaluated 10 hours after the second dose, with mean level of 0.84 micrograms/ml (0 to 1.35). Blood level was evaluated after third dose, during amygdalectomy was 1.24 micrograms/ml (0.1 to 3.9). Tonsils levels were: for right tonsils 0.74 micrograms/g and for left tonsils 0.53 micrograms/g. Cefixime was not detected in both tonsils of 6 children, and in one of the two tonsils in 11 of them. The tonsils penetration of cefixime was about 1 microgram/g in the case where cefixime was detectable. This penetration is not regular as for other betalactam antibiotics in relation with fibrosis of tonsils tissue inhibiting a good diffusion of antibiotic.
