A survey of antibiotic prescribing patterns of six physicians in two Sick Fund clinics was carried out during a one-month period. Over 1,200 antibiotic prescriptions and their therapeutic indications were reviewed. Ampicillin was the most commonly prescribed drug. Most of the prescriptions were for treatment of infections of the upper respiratory tract. Over one half of all antibiotic prescriptions were for presumably viral upper respiratory infections (URI), and half of all patients diagnosed as having viral URI received an antibiotic prescription. A method for measuring the quality of antibiotic usage by physicians in infections of the upper respiratory tract was developed and tested. The method is readily applicable to Sick Fund clinics and, in a trial run, proved capable of demonstrating large differences among physicians in their antibiotic prescribing habits for viral URI, tonsillitis, and otitis media.

Patients with acute otitis media, tonsillitis and upper respiratory tract infections were divided into 2 groups and treated with ampicillin-cloxacillin (Rectocillin) 1 g/day or ampicillin (AB-PC) 1 g/day, respectively. The therapeutic effect and side effect of these two drugs were studied comparatively by double blind tests. The effective rate in the Rectocillin group was 85.1%, and that in the AB-PC group was 86.7%. There was no significant difference in the therapeutic effect between two drugs. Ten cases in the Rectocillin group and 4 cases in the AB-PC group complained of disorders supposedly due to administration of these drugs. Such side effects in the former group were all gastrointestinal disorders, but in the latter, 2 cases of eruption, one case of headache and one case of gastrointestinal disorder.

Sulbactam/Ampicillin (SBT/ABPC), a combination at a fixed ratio of ABPC and SBT which is an irreversible inhibitor of beta-lactamase in a 2:1 ratio, was clinically evaluated for its efficacy and safety in 24 patients with ages from 5 month-old to 12 years old with bacterial infection. The results obtained are summarized as follows. 1. A pharmacokinetic study following 30 mg/kg SBT/ABPC administration by 30 minutes drip infusion or intravenous bolus injection showed that mean half-lives of SBT and ABPC were 48.9 minutes and 40.2 minutes, respectively, and mean urinary excretion rates of SBT and ABPC in the first 6 hours were 67.1% and 48.3%, respectively. 2. SBT/ABPC was administered to 14 patients with bronchopneumonia, 4 patients with tonsillitis, a patient each with acute upper respiratory infection, with submandibular lymphadenitis, with phlegmon, with enterocolitis, with pyelonephritis and with cystitis at a daily dosage of 88.2-133.3 mg/kg, divided into 3 or 4, by intravenous bolus injection or by 30 minutes drip infusion. Clinical responses of the 24 patients were as follows: excellent: 17 patients, good: 7 patients. The efficacy rate was 100%. 3. Neither clinical adverse reactions nor abnormal laboratory test values, except slight eosinophilia in a patient and an elevation of GOT, GPT in another were observed. 4. MICs of SBT/ABPC against 7 strong beta-lactamase producing strains isolated from some of the patients were as follows. MIC against a strain of Staphylococcus aureus was 3.13 micrograms/ml, MICs against 2 out of 5 strains of Branhamella catarrhalis were 0.10 microgram/ml and those of the remaining 3 strains were 0.20 microgram/ml. MIC against a strain of Haemophilus parainfluenzae was 3.13 micrograms/ml. 5. These data described above show that SBT/ABPC has excellent bactericidal capacity against beta-lactamase producing bacteria as well as beta-lactamase non-producing Gram-positive and negative bacteria and suggest that SBT/ABPC is a very useful antibiotic for pediatric patients.

BRL 25000 granules, a formulation of amoxicillin (AMPC) and the beta-lactamase inhibitor clavulanic acid (CVA) in a ratio of 2 to 1, was studied clinically and bacteriologically in pediatric infections. The in vitro antibacterial activity of BRL 25000 was superior to AMPC against beta-lactamase producing strains. The pharmacokinetics of the BRL 25000 granule were studied following oral administration to a 6 years old female and 9 years old male in the fasting state at dose levels of 10 mg/kg and 16.1 mg/kg, respectively. In the case of the female dosed at 10 mg/kg, the peak serum concentrations were found to be 6.38 micrograms/ml for AMPC and 1.83 micrograms/ml for CVA at 1 hour following administration. The elimination half-life of AMPC was 0.86 hour and that of CVA was 0.67 hour. The 4-hour urinary recovery was 61.89% for AMPC and 17.92% for CVA. In the male receiving 16.1 mg/kg, the peak concentrations were 2.55 micrograms/ml for AMPC at 3 hours following administration and 1.46 micrograms/ml for CVA at 1.5 hours following administration. The elimination half-life of AMPC was 1.59 hours and that of CVA was 1.19 hours. The 6-hour urinary recovery was 44.19% for AMPC and 30.05% for CVA. In clinical studies, the BRL 25000 granule was administered to 36 infants with upper respiratory tract infections, mainly tonsillitis, urinary tract infections etc. Good clinical efficacy was obtained in 33/36 cases (91.7%). Diarrhea and rash were occasionally noted side effects but were not severe. From the above results, it can be concluded that the BRL 25000 granule is a suitable and effective drug for use in the treatment of pediatric infections.

Fundamental and clinical studies on BRL 25000 granules were carried out in the pediatric field. BRL 25000 is a formulation comprising 1 part of clavulanic acid (CVA) and 2 parts of amoxicillin (AMPC). The MICs of BRL 25000 and AMPC were assessed against 24 clinically isolated strains of S. aureus (including 23 beta-lactamase producing strains), 22 S. pyogenes, 20 E. coli (8 beta-lactamase producing strains), 24 K. pneumoniae (24 beta-lactamase producing strains), 20 H. influenzae (6 beta-lactamase producing strains). BRL 25000 showed MIC80 (cumulatively 80% of strains were inhibited) at 6.25 micrograms/ml against S. aureus, less than or equal to 0.10 micrograms/ml against inst S. pyogenes, 12.5 micrograms/ml against E. coli, 6.25 micrograms/ml against K. pneumoniae and 0.39 micrograms/ml against H. influenzae. BRL 25000 showed no improvement in MIC terms against beta-lactamase nonproducing strains compared with AMPC. However, BRL 25000 was markedly more effective against beta-lactamase producing strains. Thus BRL 25000 was up to 8 fold more active against S. aureus, 2 to 64 fold against E. coli, 4 to 128 fold against K. pneumoniae, 4 to 16 fold against H. influenzae than AMPC. Following oral administration of BRL 25000 granules (at a dose level of 12.5 mg/kg) to 2 children aged 9 and 11 years, the mean peak serum concentrations of AMPC and CVA were 8.33 +/- 2.43 micrograms/ml and 4.44 +/- 1.65 micrograms/ml respectively 1 hour after dosing. The half-lives of AMPC and CVA were 1.35 +/- 0.42 hours and 0.91 +/- 0.05 hour, respectively. The urinary excretion was 48.21 +/- 3.83% for AMPC and 16.90 +/- 7.06% for CVA in the first 6 hours after administration. In clinical studies, 23 pediatric patients aged 2 months to 12 years with bacterial infections were treated with BRL 25000 granules and the clinical effectiveness, bacteriological response and side effects were evaluated. The clinical response was assessed in 23 cases, 3 with acute rhinitis, 6 with acute purulent tonsillitis, 5 with acute bronchitis, 4 with acute pneumonia, 3 with impetigo, 1 with furunculosis and 1 with periproctal abscess. Results were excellent in 13 cases, good in 7, fair in 3 and hence the efficacy rate (excellent and good cases) was 87.0% (20/23). In particular the clinical response in 9 cases with infections due to beta-lactamase producing organisms was excellent in 6, good in 2, fair in 1 and the efficacy rate was 88.9% (8/9).(ABSTRACT TRUNCATED AT 400 WORDS)

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)

The emergence of beta-lactamase-mediated resistance to established beta-lactam antibiotics prompted the development of beta-lactamase inhibitors for co-administration. Ampicillin has been combined with sulbactam for both parenteral and oral (as the mutual pro-drug sultamicillin) administration. The combination is active in vitro against a wide variety of Gram-positive and Gram-negative pathogens, including aerobic and anaerobic organisms. In clinical trials, ampicillin/sulbactam has proved clinically and bacteriologically effective against a variety of frequently encountered pediatric infections, including mild-to-moderate upper respiratory tract infections (acute otitis media, sinusitis, pharyngitis, and tonsillitis), severe post-operative and intra-abdominal infections, periorbital infections (which, left untreated, can lead to blindness, brain abscess, or death), acute epiglottitis, bacterial meningitis, and brain abscess. Ampicillin/sulbactam has also proved effective in the prevention of post-operative surgical infections in pediatric patients. The clinical efficacy profile of ampicillin/sulbactam and sultamicillin, combined with their excellent tolerability profile, make these agents attractive options for the management of many life-threatening infections in pediatric patients.
