cefuzonam and Tonsillitis

The concentration of CZON was determined by HPLC in surgical patients with chronic otitis media, sinusitis, and tonsillitis. One gram of CZON was injected intravenously prior to surgery. The time course of the mean tissue CZON level was as follows: In the middle ear mucosa, 3.7 micrograms/g at 15 min, 7.2 micrograms/g at 30 min, and 2.9 micrograms/g at 1 hr (the half life: 21.3 min). In the maxillary sinus mucosa, 10.5 micrograms/g at 15 min, 11.8 micrograms/g at 30 min, and 2.8 micrograms/g at 1 hr (the half life: 17.5 min). In the tonsils, 14.9 micrograms/g at 15 min, 9.3 micrograms/g at 30 min, and 2.0 micrograms/g at 1 hr (the half life: 13.2 min). The concentration was high in the maxillary sinus mucosa and the tonsils, but was low in the middle ear mucosa. In the formers the transfer ratio reached its peak 15 to 30 min after administration, but in the latter the peak was reached 30 to 60 min after administration. The order of the transfer ratio at each region was above 25%. The tissue concentration exceeded the MIC80s of frequent isolates from these infections. CZON is considered to be a highly useful drug in the treatment of these infections.

Cefuzonam (L-105, CZON) was given intravenously to 20 pediatric patients with the following acute bacterial infections: 13 of bronchopneumonia and 1 each of tonsillitis, purulent cervical lymphadenitis and acute tonsillitis, laryngitis, bronchitis, pyothorax, purulent meningitis complicated with septic arthritis, and urinary tract infection. Good clinical responses were obtained in all of the 20 patients and bacterial eradication of all 16 strains. No side effect was observed except 3 cases of slight elevation of transaminase, and 1 case each of soft stool and eosinophilia. From the above clinical results, it appears that CZON is a useful antibiotic for the treatment of pediatric patients with various kinds of bacterial infections.
