[Laboratory and clinical studies of flomoxef in the pediatric field].
We have carried out laboratory and clinical studies on flomoxef (FMOX, 6315-S). The results were summarized as follows. FMOX was given by 5-minute intravenous administration to 3 children at a single dose of 20 mg/kg. After the intravenous administration, mean serum levels of FMOX were 110.1 +/- 30.95 micrograms/ml at the end of injection, 44.4 +/- 10.55 micrograms/ml at 15 minutes, 11.0 +/- 1.72 micrograms/ml at 1 hour and 0.42 +/- 0.17 microgram/ml at 6 hours. The mean half-life was 1.14 +/- 0.30 hours. The mean urinary excretion rate was 68.8 +/- 17.4% up to 6 hours after the intravenous administration. FMOX was given by 30-minute drip infusion to 2 children at a single dose of 20 mg/kg and to 3 children at a single dose of 40 mg/kg. After the 30-minute drip infusion, mean peak serum levels of FMOX obtained for the 2 dose levels were 45.5 +/- 0.45 micrograms/ml and 87.4 +/- 18.35 micrograms/ml at the end of injection, respectively, and mean half-lives were 0.63 +/- 0.23 hours and 0.70 +/- 0.27 hours, respectively. The mean urinary excretion rate was 53.4 +/- 6.1% up to 6 hours after the 30-minute drip infusion of 40 mg/kg FMOX. Treatment with FMOX was made in 24 cases of pediatric bacterial infections; 5 cases of purulent tonsillitis, 2 cases of bronchopneumonia, 12 cases of pneumonia, and 1 case each of lymphadenitis, pyothorax, purulent meningitis, cellulitis, and abscess. Results obtained were excellent in 15 cases and good in 9 cases. No significant side effect due to the drug was observed in any cases.
