Bacteriological and clinical evaluations of BRL 25000 (1 part clavulanic acid plus 2 parts amoxicillin) granules in the pediatric field have been performed. The MICs of BRL 25000 against 25 clinically isolated strains of S. aureus, 40 E. coli, and 14 K. pneumoniae were compared with those of AMPC. Against beta-lactamase non-producing strains of S. aureus and E. coli, the MICs of both drugs were nearly equal, however, against beta-lactamase producing strains of these species and K. pneumoniae, BRL 25000 was superior to AMPC. The blood levels of AMPC and CVA after single oral administration of approximately 15 mg/kg of BRL 25000 granules to fasted children were studied in 3 subjects. The mean levels of AMPC and CVA peaked about 1 hour after administration at values of 11.40 and 5.49 micrograms/ml, respectively, with half-lives of 0.91 and 1.02 hours, and AUCs of 23.52 and 12.66 hr X micrograms/ml, respectively. The 6-hour urinary recovery of AMPC ranged from 30.59% to 52.03% and for CVA from 16.31% to 45.18%. There was no significant difference between the blood level of AMPC following single oral administration of approximately 10 mg/kg AMPC granules and that of AMPC following single oral administration of approximately 15 mg/kg BRL 25000 granules to the same children. Clinical evaluation of BRL 25000 granules administered orally 3-4 times a day at total daily doses of between 42.9-52.9 mg/kg resulted in improvement, judged excellent or good, in all 7 cases of tonsillitis and 2 cases of pyelonephritis. In particular, the clinical effect was excellent in the case of tonsillitis where a beta-lactamase producing H. influenzae was isolated. In the total 11 cases treated, including 2 cases of mycoplasmal pneumonia excluded from the clinical evaluation, 1 case of rash and eosinophilia was observed. No other adverse reactions or abnormal laboratory findings were observed. The taste and flavor of the drug were well accepted by the children. It was concluded that BRL 25000 granules are promising new drug which should be markedly useful in the treatment of infections in pediatric outpatients.

MICs of BRL 25000, a combination of a newly developed beta-lactamase inhibitor CVA and AMPC in the ratio of 1 to 2, were determined against a number of bacterial strains and compared with those of AMPC, CVA, CEX and CCL. The 98 bacterial strains tested included 2-S. aureus, 23-H. influenzae, 25-E. coli, 22-K. pneumoniae and 26-P. mirabilis. In pharmacokinetic studies, BRL 25000 medium granules were administered to groups of 3 male subjects, aged between 7 years 8 months and 9 years 5 months, at doses of 10, 15 and 20 mg/kg, 2 hours after a meal. The resultant serum and urine concentrations and drug recoveries were measured. Furthermore, BRL 25000 was administered to a total 43 patients (2-pharyngitis, 8-tonsillitis, 3-bronchitis, 2-pneumonia and 28-urinary tract infection) whom clinically evaluable. An average daily dosage of 45.3 mg/kg was given, in 3 or 4 divided doses, for a period of 8 days on average. Clinical and bacteriological effects as well as side effects were studied. In the microbiological studies on 98 clinical strains, including beta-lactamase negative bacteria, BRL 25000 showed MICs against the Gram-positive cocci (2-S. aureus) superior to the other 4 drugs at inoculum sizes of 10(8) and 10(6) cells/ml. For the Gram-negative bacilli, against H. influenzae at inoculum sizes of 10(8) and 10(6) cells/ml, BRL 25000 was inferior in the small MIC range but superior in the large MIC range to AMPC, and was superior to the other 3 drugs. Against E. coli at an inoculum of 10(8) cells/ml, BRL 25000 showed antibacterial activity next to AMPC and CCL whilst at an inoculum of 10(6) cells/ml, it was inferior in the small MIC range but superior in the large MIC range to AMPC and CEX and was inferior to CCL but superior to CVA. Against K. pneumoniae at an inoculum of 10(8) cells/ml, BRL 25000 was equal to AMPC, CVA and CEX but inferior to CCL, whilst at an inoculum of 10(6) cells/ml, it was inferior to CCL but superior to the other 3 drugs. Against P. mirabilis at inoculum sizes of 10(8) and 10(6) cells/ml, BRL 25000 was inferior in the small MIC range but equal or superior in the large MIC range to AMPC, and was superior to CVA and CEX.(ABSTRACT TRUNCATED AT 400 WORDS)

Bacteriological, pharmacokinetic and clinical studies on SY5555 dry syrup (powder which is dissolved before use), a new penem antibiotic for oral use, were performed. The following results were obtained. 1. Antibacterial activities. MICs of SY5555, clavulanic acid/amoxicillin (CVA/AMPC), cefotiam (CTM), cefpodoxime (CPDX), cefaclor (CCL) and cefdinir (CFDN) were determined against clinically isolated Staphylococcus aureus, coagulase negative staphylococci, Streptococcus pneumoniae, Streptococcus pyogenes, Haemophilus influenzae, Moraxella catarrhalis, Escherichia coli and Enterobacter cloacae at a dose of 10(6) CFU/ml. MICs of SY5555 against S. aureus, CNS, S. pneumoniae, S. pyogenes, H. influenzae, M. catarrhalis, E. coli and E. cloacae were 0.2, 0.2, 0.2, < or = 0.025, 0.78, 0.2, 0.78 and 3.13 micrograms/ml, respectively, showing excellent antibacterial effects on these pathogens. Although the effects of SY 5555 against H. influenzae and E. coli were slightly inferior to those of CPDX and CFDN, the drug showed the most excellent antibacterial effect on other strains as compared with the control drugs. 2. Absorption and excretion In this study, plasma concentrations and urinary recovery rates were examined after administration of SY5555 at doses of 5 and 10 mg/kg (potency) after meals. With both 5 and 10 mg/kg doses, peak plasma concentrations were reached 1 hour after administration, at 0.25-2.61 micrograms/ml (mean 1.47 micrograms/ml) and 1.08-2.17 micrograms/ml (mean 1.74 micrograms/ml), respectively. The plasma levels rapidly decreased to 0.06-0.19 micrograms/ml (0.12 micrograms/ml) and 0.0503-0.0637 micrograms/ml) after 6 hours. The half-lives 1.12 hours in the 5 mg/kg group and 1.0 hour in the 10 mg/kg group. The urinary recovery rates were determined in the first 8 hours after administration in the 5 mg/kg and 6 hours in the 10 mg/kg group, and the values were as low as 1.05-12.3% and 1.6-4.33%, respectively. 3. Clinical results The clinical responses were examined in a total of 73 cases including 4 acute pneumonia, 13 acute bronchitis, 11 tonsillitis, 3 pharyngitis, 12 scarlet fever, 2 pertussis, 6 urinary tract infection, 6 otitis media, 7 lymphadenitis, 2 staphylococcal scalded skin syndrome, 2 phlegmon, 4 impetigo and 1 purulent parotitis. The treatment was effective or better in 66 of 70 cases with an efficacy rate of 94.3% (3 undeterminable cases were excluded). Bacteriological effects were examined during the clinical course for detected or suspected pathogens found before administration of SY5555. The effects were determined in 50 cases including 7 cases of polymicrobacterial infections, 57 strains in total. Eight strains, however, persisted, hence the overall eradication rate was 86.0%.(ABSTRACT TRUNCATED AT 400 WORDS)

Nasal sinusitis, tonsillitis, and pharyngolaryngitis typify upper respiratory tract infections, while bronchitis and pneumonia typify lower respiratory tract infections. Cases of paranasal sinusitis with severe suppuration are reportedly becoming less frequent, while those of chronic catarrhal paranasal sinusitis and edematous allergic paranasal sinusitis are becoming more so, The primary factor in paranasal sinusitis, a typical infectious disease encountered in otolaryngology, is bacterial infection. The main causative bacteria are Streptococcus pneumoniae, reported in 13.4% of cases, Haemophilus influenzae in 12.8% Moraxella catarrhalis in 5.5%, Staphylococcus aureus in 26.5%, Pseudomonas aeruginosa in 5.2%, and anaerobes. The incidence of strains resistant to antimicrobial agents has grown for S. pneumoniae, H. influenzae, and M. catarrhalis and decreased for S. aureus and P. aeruginosa. Acute exacerbation or severe suppuration in chronic paranasal sinusitis requires the administration of antimicrobial agents, with the same agent administered 2 weeks for maximal effect. First-line agents are AMPC/CVA, SBTPC, CDTR-PI, CFPN-PI, and GFLX for adults, with ASPC, SBPC, ACPC, CTRX, CMZ, FMOX, PAPM/BP, and MEPM injected in severe cases. Attention must be paid to strains that resist cephems and macrolides, such as PISP, PRSP, and BLNAR. In refractory chronic paranasal sinusitis, attention must also be paid to biofilms produced by S. aureus and P. aeruginosa. Suitable antimicrobial agents should be determined for treating of chronic paranasal sinusitis, in addition to the best procedure to ensure early recovery from inflammation, such as puncturing or irrigating the maxillary sinus, injecting a suitable agent, nebulization, and/or surgically widening the middle meatus.
