[Pharmacokinetic, bacteriological and clinical studies on S-1108 in children].
Pharmacokinetic, bacteriological and clinical studies on S-1108 were performed in children. The results were as follows: 1. A total of 11 patients were treated with S-1108. Each dose was 3 mg/kg, orally administered 3 times daily for 4-14 days. The clinical efficacies of S-1108 in 10 patients with bacterial infections (1 with bacteremia, 4 with pneumonia, 1 with acute maxillary sinusitis, 1 with scarlet fever and 2 with streptococcal pharyngitis) were evaluated as excellent in 8 patients and as good in 2 patients with an efficacy rate of 100%. Only one patient with staphylococcal scalded skin syndrome due to methicillin resistant Staphylococcus aureus (MRSA) who received gamma-globulin was not evaluated. Fourteen causative strains of 5 species were found in 10 patients. Three strains of Streptococcus pneumoniae out of 5, 2 of 3 Branhamella catarrhalis strains, none of Staphylococcus aureus and all 3 strains of Streptococcus pyogenes were eradicated. No adverse reaction was observed in any of the 11 patients. 2. MICs of S-1108 against 5 clinically isolated S. pneumoniae from cases of infections were examined. All of them were relatively highly resistant to penicillins. S-1108 was compared with cefteram pivoxil, cefpodoxime proxetil, cefaclor and cefixime, and it showed better antibacterial activity or than other cephems. 3. Double peaks were obtained in plasma levels of S-1108 orally administered at a dose of 3 mg/kg at 30 minutes after meal and were 1.03 microgram/ml and 0.74 microgram/ml at 1 and 4 hours after administration, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
