[Pharmacokinetic and clinical experience with flomoxef in bacterial infection in children].

Abstract

Pharmacokinetic and clinical studies were performed on flomoxef (FMOX, 6315-S), a new oxacephem antibiotic, as follows. 1. Pharmacokinetics Serum concentrations of FMOX were measured in 2 cases given 20 mg/kg bolus injection. In the 2 cases, peak concentrations of the drug were 44.3 and 197 micrograms/ml at 15 minutes, T1/2 (beta) were 0.76 and 0.47 hour and AUC were 44.8 and 169.5 micrograms.hr/ml, respectively. Urinary recovery rates for these cases during 6 hours were 83.1 and 54.9%, respectively. The extremely high peak serum concentration in one case may be attributed to dehydration. 2. Clinical efficacy FMOX was administrated intravenously to 12 patients, 6 with pneumonia, 2 with cellulitis, 1 each with bronchitis, tonsillitis, purulent lymphadenitis and subcutaneous abscess, in doses of 55.0-120.0 mg/kg (average 82.2 mg/kg) t.i.d. for 4-13 days (average 6.2 days). The overall efficacy rate was 100%, with excellent responses in 10 and good in 2. Bacteriological efficacy was excellent; 4 of 5 strains were eradicated and 1 strain was decreased. No clinical side effect was observed. Laboratory abnormality was observed in 1 case with transient eosinophilia. The above results suggested that FMOX would be an useful antibiotic for treating pediatric bacterial infections.
