Abstract

Fundamental and clinical studies were carried out on cefixime (CFIX) 5% granules, and the results are summarized below. Antimicrobial activity Antimicrobial activities of CFIX, cefaclor, cefroxadine, cephalexin and amoxicillin (AMPC) were studied against clinical isolates. CFIX showed greater activities than all the other antibiotics against E. coli, K. pneumoniae, H. influenzae, P. mirabilis, E. cloacae and S. marcescens, but it was slightly less active than AMPC against S. pyogenes. Absorption and excretion Serum concentrations and urinary excretions of CFIX were determined following single or repeated oral administration. In 8 patients given single dose of CFIX 1.5 or 3.0 mg/kg, mean serum concentrations were 1.27 and 1.09 micrograms/ml at 2 hours, 1.27 and 1.35 micrograms/ml at 4 hours, 0.85 and 1.10 micrograms/ml at 6 hours, 0.17 and 0.24 micrograms/ml 12 hours after administration, respectively. Mean serum half-lives were 2.54 hours for the dose of 1.5 mg/kg and 2.60 hours for 3.0 mg/kg. Urinary recovery rates in the 12-hours urine varied 6.7 to 33.6%, with an average of 13.5%. In 3 patients given a repeated dose of CFIX 3.0 or 5.6 mg/kg b.i.d., the serum concentrations were 0.23-1.01 micrograms/ml at 0 hour, 1.91-2.80 mi...Continue Reading
