Pharmacokinetic, bacteriological, and clinical studies on cefdinir (CFDN, FK482) (10% fine granules), a new oral cephem, were performed in pediatrics. 1. Bioequivalencies of plasma concentrations and urinary excretions of CFDN 5% and 10% fine granules were investigated on 3 pediatric patients with ages between 5 to 13 years administered with a drug in fasting state at a dose level of 3 mg/kg using a cross over method. Average plasma concentrations in a group of patients administered with 5% fine granules peaked at 3 hours after administration with a level of 1.05 +/- 0.29 micrograms/ml (mean +/- S.E.) and decreased to 0.12 +/- 0.05 micrograms/ml at 8 hours with a half-life of 1.48 +/- 0.09 hours. In the group administered with 10% fine granules, average plasma concentrations peaked at 2 hours after administration with a level of 1.32 +/- 0.12 micrograms/ml, and decreased to 0.20 +/- 0.11 microgram/ml at 8 hours with a half-life of 1.68 +/- 0.28 hours. The first 8-hour urinary recovery rates of CFDN in the 5% and 10% fine granules groups averaged 19.64 +/- 5.69% and 23.37 +/- 2.36%, respectively. Both average and individual plasma concentrations and urinary recovery rates in the patients of the 10% fine granules group were somewhat higher than those of the 5% fine granules group, but no significant differences were observed between the 2 groups including areas under concentrations. 2. CFDN 10% fine granule preparation was administered to 33 pediatric patients with ages between 1 to 13 years with various infections, and its clinical effects, bacteriological effects and safety were assessed. In 31 of the 33 patients (2 patients were excluded since they were with non-bacterial infections) clinical effects were excellent in all of 9 patients with scarlet fever (3), acute pharyngitis (3) or impetigo (3), excellent in 12 and good in 3 of 15 patients with acute purulent tonsillitis, and excellent in 4 and good in 3 of 7 patients with acute pneumonia. The overall efficacy rate was 100%. Bacteriological effects against causative organisms were evaluated. All the identified Staphylococcus aureus (4 strains) and Streptococcus agalactiae (1) were eradicated. Of 10 strains of Streptococcus pyogenes, 9 strains were eradicated and the other one was reduced. Of 7 strains of Haemophilus influenzae 4 were eradicated, 1 persisted and the fate of the remaining 2 were unknown. The overall eradication rate was 90.0%. Microbial substitutions were observed in 5 patients. The new, replacing bacteria were all Haemophilus spp.(ABSTRACT TRUNCATED AT 400 WORDS)

We have carried out laboratory and clinical studies on cefdinir (CFDN) 5% and 10% fine granule preparations. The results are summarized as follows. CFDN 5% fine granule preparation was given via oral route to each of 2 children in the fasting state at a single dose of 3 mg/kg. After administration, the mean peak plasma level of CFDN was 0.76 micrograms/ml at 4 hours and the mean half-life was 1.77 hours. The mean urinary excretion rate of CFDN was 31.5% in the first 12 hours after oral administration. CFDN 10% fine granule preparation and CFDN 100 mg capsule were given via oral route 3 children and to another child in the fasting state at single doses of 3 mg/kg and 2.63 mg/kg, respectively. After administration of 10% granules the mean peak plasma level of CFDN was 0.73 micrograms/ml at 2 hours and the mean half-life was 1.62 hours. The peak serum level obtained after administration of CFDN 100 mg capsule was 0.91 micrograms/ml at 2 hours and the half-life was 1.08 hours. The mean urinary excretion rate obtained with CFDN 10% fine granules was 26.2% in the first 8 hours after oral administration and the urinary excretion rate obtained with CFDN 100 mg capsule was 19.7% in the first 12 hours after oral administration. Treatment with CFDN 5% fine granules was made for a total of 48 cases of pediatric bacterial infections including 21 cases of tonsillitis, 12 cases of scarlet fever, 3 cases of pharyngitis, 5 cases of impetigo, 1 case of subcutaneous abscess, 1 case of furuncle, 5 cases of UTI. Results obtained were excellent in 30 cases, good in 18 cases. Treatment with CFDN 10% fine granules was made for a total of 16 cases of pediatric bacterial infections including 6 cases of tonsillitis, 3 cases of pneumonia, 4 cases of scarlet fever, 2 cases of impetigo, 1 case of UTI. Results obtained were excellent in 8 cases, good in 7 cases, poor in 1 case. No significant side effects due to the drugs were observed except 2 cases (1 case with 5% preparation and another with 10%) with eosinophilia, 3 cases (all with 5%) with diarrhea and 1 case each of elevated GOT & GPT (with 5%) and elevated GOT, GPT & Al-P (with 10%).

Cefdinir (CFDN), a newly developed oral cephalosporin in 5% fine granular form, was administered to 10 boys at 1 hour before meal (in the fasting state) and concentrations of the drug in plasma and urine and its urinary recovery rates were determined. The subjects were divided into 2 groups of 5 boys each; one group received 3 mg/kg of CFDN, and the other, 6 mg/kg. To 6 of the 10 children the drug was administered in the two different dose levels using the cross-over method. To study clinical and bacteriological effects of this drug, a mean dose of 4.6 mg/kg t.i.d. was administered for 8 days on the average to 40 children with various infections; pharyngitis (4 cases), tonsillitis (2), acute bronchitis (2), pneumonia (8), scarlet fever (6), acute purulent otitis media (1), urinary tract infection (12), impetigo (2), phlegmon (1), lymphadenitis (1) and subcutaneous abscess (1). MICs were determined for 6 drugs including CFDN, cefaclor, cefixime (CFIX), methicillin, cloxacillin (MCIPC), amoxicillin (AMPC) against 13 strains of 6 species freshly isolated from children receiving CFDN. An inoculum size of 10(6) cfu/ml was used in the MIC-determinations. Adverse reactions and abnormal laboratory findings attributable to this drug were also examined in these patients. The results obtained are summarized as follows. 1. Mean plasma peak levels of CFDN were observed at 3 hours after administration in both the 3 mg/kg and 6 mg/kg groups with mean peak values of 0.68 and 1.35 micrograms/ml, respectively. Mean half-lives were 2.06 hours in the 3 mg/kg group and 1.61 hours in the 6 mg/kg group, and mean AUCs were 3.5 in the former and 6.5 micrograms.hr/ml in the latter. Thus, dose-response between the 2 doses was observed in plasma levels and AUCs. 2. To 3 patients, CFDN was given in the two different doses using the cross-over method. Mean plasma peak levels of CFDN were 0.71 and 1.31 micrograms/ml in the doses of 3 mg/kg and 6 mg/kg, respectively. Half-lives were 1.39-2.90 hours in the 3 mg/kg group and 1.21-1.48 hours in the 6 mg/kg group, with AUCs of 3.4-3.7 and 4.1-7.5 micrograms.hr/ml, respectively.(ABSTRACT TRUNCATED AT 400 WORDS)

We have carried out laboratory and clinical studies on norfloxacin (NFLX, AM-715). The results are summarized as follows. NFLX was given through oral administration to one child each at dose levels of 1.7 mg/kg, 2.4 mg/kg and 3.2 mg/kg. After administration, peak serum levels of NFLX obtained for the 3 dose levels were 0.16 micrograms/ml at 1 hour, 0.69 micrograms/ml at 2 hours, 0.81 micrograms/ml at 1 hour, respectively, and half-lives were 2.5 hours, 1.8 hours and 2.7 hours, respectively. NFLX was given through oral administration to 2 children at a dose level of 4.4 mg/kg and to another child at a dose level of 4.8 mg/kg. After administration, mean peak serum levels of NFLX obtained were 1.17 +/- 0.48 micrograms/ml and half-lives were 3.0 +/- 0.5 hours. Urinary excretion rates of NFLX were 14.5% and 28.4% in the first 8 hours after administration of 1.7 mg/kg and 3.2 mg/kg, respectively, and 29.1% in the first 6 hours after administration of 2.4 mg/kg. Mean urinary excretion rates of NFLX were 38.5 +/- 13.0% in the first 8 hours after administration of 4.4 mg/kg and 4.8 mg/kg. Treatment with NFLX was made in 33 cases of pediatric bacterial infections including 5 cases of tonsillitis, 14 cases of enteritis, 10 cases of UTI and 1 case each of bronchitis, balanoposthitis, impetigo and pustulosis.

A newly developed macrolide clarithromycin (TE-031, A-56268), with antibacterial spectrum and antibacterial activity nearly equal to those of erythromycin (EM), shows beneficial characteristics such as a higher blood level, higher recovery rate in urine, and better penetration into each tissue than conventional macrolides (MLs). TE-031 has been studied in adults against various infections and proved to be useful. The present paper describes the results of a study in children to examine the usefulness of TE-031 granules and tablets with a potency of 50 mg. TE-031 granules were administered to 132 children with ages from 6 months to 13 years and 10 months. Excluded from the evaluation were 12 cases in which clinical effects were deemed unevaluable. The evaluable subjects consisted of 1 case with pharyngitis, 3 with tonsillitis, 9 with acute bronchitis, 19 with pneumonia, 19 with mycoplasmal pneumonia, 2 with scarlet fever, 20 with Campylobacter enteritis, 11 with impetigo, 2 with subcutaneous abscess, 18 with primary atypical pneumonia and 16 with acute enteritis of unidentified pathogens; a total of 120 subjects. An average daily dose of TE-031 was 25.9 mg/kg, divided into 3 doses except 1 case with 2 daily doses and lengths of the treatment averaged 7 days. TE-031 tablets each containing 50 mg potency, were administered to 49 subjects with ages from 3 year and a month to 14 years consisting of 8 cases with pharyngitis, 1 with tonsillitis, 1 with acute bronchitis, 4 with pneumonia, 14 with mycoplasmal pneumonia, 4 with scarlet fever, 5 with Campylobacter enteritis, 7 with impetigo, 1 with atypical pneumonia, 1 with Salmonella gastroenteritis and 3 with acute enteritis caused by unidentified pathogens, at an average daily dose of 13.5 mg/kg dived into 2-4 doses (2 doses/day for 12 cases, 3 doses for 32, 4 doses for 5) for 7 days on the average. In addition to examine the clinical and bacteriological effects of the 2 dosage forms of TE-031, minimum inhibitory concentrations (MICs) were determined for 9 antibiotics consisting of 5 MLs including TE-031, EM, josamycin (JM), midecamycin acetate (MDM acetate), and rokitamycin (RKM), 3 penicillins including ampicillin (ABPC), methicillin, cloxacillin and 1 cephem antibiotic, cefaclor (CCL), against 29 strains consisting of 12 strains of Staphylococcus aureus, 7 of Streptococcus pyogenes, 2 of Streptococcus pneumonia 2 of Haemophilus influenzae and 6 of Campylobacter jejuni, out of 71 strains of pathogens or possible pathogens that had been isolated from the cases given TE-031.

A molecular epidemiology analysis was performed with over 440 clinical isolates of Streptococcus pyogenes obtained from 11 different countries in order to determine the frequency of occurrence of the type A streptococcal exotoxin (erythrogenic toxin) gene (speA) among group A strains. The colony hybridization technique employing a specific internal fragment of the speA gene was used for initial screening, and all positive results were further confirmed by the Southern hybridization technique. Among over 300 general strains obtained from patients with a variety of diseases, except scarlet fever (such as tonsillitis, impetigo, cellulitis, pyoderma, abscess, rheumatic fever, and glomerulonephritis), 15% were found to contain the speA gene. Among a group of 146 strains obtained from individuals described as having scarlet fever, 45% were shown to contain the speA gene. Further analysis of the data indicated that strains with certain M- or T-type surface antigens showed a higher (such as M and T types 1 and 3/13) or lower (such as M2, M12, T4, T5, and T28) tendency to contain the speA gene. No correlation was found between speA content of a strain and the ability to cause a specific disease, although strains possessing the speA gene were more likely to be associated with scarlet fever and rheumatic fever than with other types of disease.

During 8 months from October 1986 to May 1987, the clinical efficacy of sulbactam/ampicillin (SBT/ABPC) was evaluated in 63 pediatric inpatients with various infections. Clinical efficacies were evaluable in 58 patients among them (consisting of 2 patients with sepsis, 3 with tonsillitis, 12 with bronchitis, 6 with bronchopneumonia, 24 with pneumonia, 1 with phlegmon, 2 with lymphadenitis, 1 with impetigo and 7 with urinary tract infection) and were excellent in 40 patients and good in 17 with an overall efficacy rate of 98.3%. Bacteriological efficacies were assessed in 25 patients and 27 strains of organisms (consisting of 3 strains of Staphylococcus aureus, 2 Streptococcus pneumoniae, 1 Streptococcus pyogenes, 2 beta-Streptococcus, 1 Gram-positive cocci, 5 Escherichia coli, 1 Enterobacter aerogenes, 7 Haemophilus influenzae, 2 Haemophilus parainfluenzae, 1 Branhamella catarrhalis, 1 Proteus mirabilis and 1 Salmonella subgenus I). Bacteriological eradication rates were 88.9% for Gram-positive organisms, 66.7% for Gram-negative organisms and 74.1% overall. No superinfection was observed in any of patients treated. Side effects and clinical laboratory parameter abnormalities observed consisted of diarrhea in 7 (11.1%) of the 63 patients, eosinophilia in 2 (3.3%) of 61 tested, thrombocytosis in 3 (5.5%) of 55, elevation of direct bilirubin in 1 (3.3%) of 30, elevation of total bilirubin in 1 (3.1%) of 32, elevation of GOT in 4 (6.8%) of 59 and elevation of GPT in 1 (1.7%) of 59 patients tested. As an effect on the hemostatic mechanism of this drug, PIVKA II was detected in 1 patient (4.2%) of 24 tested, but findings of other coagulation tests were normal and none of patients showed bleeding tendency or inhibition of platelet aggregation. From the above results, it appears that SBT/ABPC is an efficacious and safe drug in the treatment of bacterial infections of pediatric patients.

Dry syrup and tablet of newly developed cefpodoxime proxetil (CS-807, CPDX-PR) was investigated in the departments of pediatrics of 17 institutes and their related hospitals. 1. Pharmacokinetics of CPDX-PR in pediatrics were investigated. Peak blood levels of CPDX at dose levels of 3 mg/kg and 6 mg/kg were 2.24 +/- 0.21 and 4.68 +/- 0.54 micrograms/ml, respectively, in fasting and 1.65 +/- 0.07 and 3.71 +/- 0.41 micrograms/ml, respectively, after meal. Urinary recovery rates in 6 hours were 31.2 +/- 2.2% of dose in average. 2. Clinical efficacies of CPDX-PR on various infectious diseases were studied in 748 cases. Clinical efficacy rate in 499 cases with causative bacteria isolated was 94.6%: efficacy rates for individual infections were 96.8% (120/124) for tonsillitis, 96.0% (96/100) for urinary tract infection, 93.5% (58/62) for pneumonia, 92.4% (61/66) for impetigo, 100% (32/32) for scarler fever and 93.2% for pharyngitis or laryngitis. Bacteriological eradication rate for Gram-positive organisms was 91.0% (244/268); and for Gram-negative organisms, 89.7% (210/234). The clinical efficacy rate for cases which were non-responsive to previous antibiotic therapy was 88.1% (74/84). 3. Side effects and clinical laboratory findings were investigated in 779 cases. Two each of vomiting, loose stool and rash, 10 of diarrhea and 1 of diarrhea associated with candidiasis were reported, but no serious side effects were noted. There was no serious laboratory test abnormality except slight elevations of eosinophile, platelet, transaminase or prolongation of prothrombin time, totalling 34 occurrences.

We have carried out laboratory and clinical studies on sulbactam/ampicillin (SBT/ABPC). The results are summarized as follows. SBT/ABPC was given by 30-minute drip infusion to 1 child at a single dose of 15 mg/kg and to 2 children at a single dose of 30 mg/kg. After the 30-minute drip infusion, peak serum levels of ABPC(SBT) obtained for the 2 dose levels were 18.0 micrograms/ml (12.4 micrograms/ml) for the former dose level and 81.0 micrograms/ml (53.7 micrograms/ml) and 300 micrograms/ml (200 micrograms/ml) for the latter at the end of injection, and half-lives were 0.84 hour (0.82 hour) for the former and 0.96 hour (1.44 hours) and 0.93 hour (1.19 hours) for the latter. In another trial, SBT/ABPC was given to 1 child at a single dose of 60 mg/kg. After the 30-minute drip infusion, peak serum level of ABPC (SBT) was 82.3 micrograms/ml (45.9 micrograms/ml), and half-life was 1.20 hours (1.36 hours). The urinary excretion rates of ABPC (SBT) were 51.3% (49.5%), 55.8 +/- 10.4% (65.3 +/- 9.1%), 74.0% (76.1%) up to 6 hours after the 30-minute drip infusion of 15 mg/kg, 30 mg/kg and 60 mg/kg, respectively. Treatment with SBT/ABPC was made in 21 cases of pediatric bacterial infections: 8 cases of tonsillitis, 4 cases of bronchitis, 3 cases of pneumonia and 1 case each of pharyngitis, peritonsillar abscess, lymphadenitis, impetigo, abscess and urinary tract infection. Results obtained were excellent in 14 cases, good in 7 cases. No significant side effect due to the drug was observed in any cases except 1 case of fever and rash.
