Cefprozil (CFPZ, BMY-28100) granules was administered to a group of pediatric patients. The new oral cephalosporin, CFPZ, was evaluated clinically in 42 pediatric patients, and a pharmacokinetic study was performed in 6 patients. Serum and urinary concentrations of CFPZ were determined in 6 patients who were given single dose of 7.5 or 15.0 mg/kg. Serum concentrations were determined at 1, 2, 3, 4 and 6 hours after dosing. Urinary concentrations were measured for periods of 0-6 hours after dosing. With oral administrations of 7.5 mg/kg and 15.0 mg/kg, peak serum concentrations were 2.13 micrograms/ml and 6.22 micrograms/ml, respectively, at 2 hours, and biological half-lives were 1.06 hours and 1.36 hours, respectively. Urinary recovery rates were 44.8% and 56.1%. The clinical evaluation was conducted in 41 patients including 16 patients with acute tonsillitis, 8 patients with lacunar tonsillitis, 4 patients with scarlet fever, 3 patients with acute bronchitis, 1 patient each with pertussis, furuncle, impetigo and lymphadenitis, and 6 patients with urinary tract infections. The ages of the patients were 10 month to 11 years 1 month, and they were treated with CFPZ at doses ranging 9.0-45.0 mg/kg daily for 3-14 days, the overall clinical efficacy rate was 92.7%. An eradication rate of 79.2% was achieved for 28 strains of 8 species identified in the patients. No side effects were observed. Abnormal laboratory test results obtained were eosinophilia in 2 patients.

Clarithromycin (TE-031, A-56268) is a new 14-membered ring macrolide antibiotic developed by Taisho Pharmaceutical Co., Ltd. TE-031 has a methoxy group at position 6 in its structure. In the present study, we carried out laboratory and clinical investigations on TE-031 in the field of pediatrics. The obtained results are summarized as follows. The antibacterial activity of TE-031 was investigated against 16 clinically isolated strains of Streptococcus pyogenes, Staphylococcus aureus, Haemophilus influenzae, Bordetella pertussis and Campylobacter jejuni. TE-031 showed antibacterial activity comparable to erythromycin. The pattern of changes in TE-031 concentrations in the blood after administration was investigated. In subjects administered the granular preparation of TE-031, Cmax values were 0.64 micrograms/ml in 1 subject given a 5 mg/kg dosage, and 5.94 and 9.02 micrograms/ml in 2 subjects administered with 10 mg/kg. The tablet form of TE-031 was administered to 3 subjects at 5 mg/kg, and Cmax values were 2.09-3.92 micrograms/ml, while T 1/2 values were in a range of 2.9-3.8 hours. When drug concentrations in the urine were investigated, it was found that 6-hour recovery rates were 9.9% (dose: 5 mg/kg) and 53.4% (dose: 10 mg/kg) in the subjects administered the granular form, whereas recovery rates averaged 36.8% in the tablet-administered subjects. In the clinical trial, TE-031 was administered in 2-3 doses/day for 2-18 days. In cases given the granular form, dosages were 12-38 mg/kg/day, while tablets were administered at 12-29 mg/kg/day. The overall clinical efficacy rate was 92.8%, i.e., the drug was effective in 64 of 69 patients. TE-031 was ineffective in 1 case of otitis media, but efficacious in 10 of 10 (100%) cases of upper respiratory infection, 15 of 18 (83.3%) cases of bronchitis and pneumonia, 5 of 6 (83.3%) cases of pertussis, 13 of 13 (100%) cases of mycoplasmal pneumonia, 4 of 4 (100%) cases of Chlamydia psittaci pneumonia, 16 of 16 (100%) cases of gastroenteritis (including 15 cases of Campylobacter gastroenteritis), and 1 (100%) case of impetigo. In bacteriological studies conducted on the patients, the overall elimination rate was 93.1%, i.e., bacterial elimination was obtained in 27 of 29 cases. TE-031 showed especially good bacteriological efficacy (100%) against C. jejuni and B. pertussis, which were eliminated from all of 15 and 2 cases examined, respectively.(ABSTRACT TRUNCATED AT 400 WORDS)

Cefteram pivoxil (CFTM-PI), the pivaloyloxymethyl ester of cefteram (CFTM) in which aminothiazol was also introduced into the 7 position of cephem nucleus, is a new oral cephem antibiotic. CFTM-PI was absorbed through the intestines and hydrolyzed to CFTM by esterases in the intestinal wall and existed in the body fluids as CFTM. A tablet form of this drug has been released in Japan and now a granular form for pediatric patients has been developed. We have determined MICs of 5 drugs (CFTM, cephalexin (CEX), cefaclor (CCL), ampicillin (ABPC), erythromycin (EM], against stock strains and MICs of 6 drugs (CFTM, CEX, CCL, ABPC, methicillin, cloxacillin) against fresh strains from patients received to CFTM-PI, with an inoculum size of 10(6) cfu/ml. A total of 149 strains included Gram-positive cocci i.e. Staphylococcus aureus (11), Streptococcus pyogenes (85), Streptococcus agalactiae (16) and Streptococcus pneumoniae (4), and Gram-negative rods i.e. Haemophilus influenzae (11), Bordetella pertussis (11), Escherichia coli (9), Proteus mirabilis (1) and Morganella morganii (1). The granular form of CFTM-PI was administered to 9 boys (age: 8 years 3 months approximately 10 years 10 months) to determine serum and urinary concentrations of the drug and its urinary recovery rates using bioassay. Doses of 1.5, 3.0 and 6.0 mg/kg were given orally 30 minutes after meal to 3 boys, respectively. Urinary concentrations and its urinary recovery rates of T-2525A, a main metabolite of CFTM, were determined using high performance liquid chromatography (HPLC). To study clinical and bacteriological effects of this drug, a mean daily dose of 3.3 mg/kg divided 3-4 times a day (3 times: 133 cases, 4 times: 9 cases) was administered for 8 days on the average to a total of 142 cases with pharyngitis (22), tonsillitis (12), acute bronchitis (3), pneumonia (11), pleurisy (1), scarlet fever (28), acute purulent otitis media (16), impetigo (13), abscess (2), purulent lymphadenitis (1) and urinary tract infection (33). Adverse reactions and abnormal effects on laboratory test values attributable to this drug were studied in patients. The results obtained are summarized as follows. 1. With regard to Gram-positive cocci, MICs of CFTM against 11 fresh strains of S. aureus ranged from 3.13 to 6.25 micrograms/ml except for 1 strain, thus CFTM was equally effective to CEX, but less active than the other drugs tested.(ABSTRACT TRUNCATED AT 400 WORDS)

Ceftazidime (CAZ), developed by Glaxo U.K., was used in pediatric patients with acute infections, and the following results were obtained. The mean blood concentrations of CAZ in 2 children were 142, 70.3, 46.9, 35.7, 16.2, 5.82 and 2.36 micrograms/ml at 5, 15, 30 minutes, 1, 2, 4 and 6 hours, respectively, after start of 5 minutes' intravenous injection of 20 mg/kg, with the half-life of 1.25 hours. CAZ was administered to 19 pediatric patients with acute infections. Out of them, 15 patients, i.e., 3 with acute tonsillitis, 1 with acute bronchitis, 5 with bronchopneumonia, 2 with pertussis accompanying pneumonia, 2 with Salmonella enteritis, 1 with impetigo staphylogenes and 1 with subdural abscess, were adopted for the evaluation, and the other 4 were excluded from the evaluation because of inadequate indications. The efficacy rate in these 15 cases was 93.3%. The doses used in 14 out of the evaluated 15 cases ranged from 31 to 50 mg/kg/day, the frequency of dosing was twice daily in 8 cases and 3 times daily in 7 cases. One shot intravenous injection was used in 6 cases, intravenous drip infusion in 8, and combination of these, in 1 case. The duration of treatment was 2 days in 3 cases, 3 days in 3, 4 days in 4, and 5 days in 3 cases. Patients with severe infections were generally given large doses for long-term. No clinical adverse event was observed in any case. In laboratory examinations, slight elevation of S-GPT alone was observed in 1 case. From the above results, CAZ was considered to be a highly useful drug in the field of pediatrics.

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)

Bacteriological, pharmacokinetic and clinical studies on cefditoren pivoxil (CDTR-PI, ME 1207) in granules, a new oral cephalosporin, were performed in the field of pediatrics. The results are summarized below. 1. Antibacterial activities: Antibacterial activities of CDTR were studied against Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes, Haemophilus influenzae, Haemophilus parainfluenzae and Branhamella catarrhalis in comparison with those of cefteram (CFTM), cefixime (CFIX), cefaclor (CCL), cefpodoxime (CPDX) and cefotiam (CTM). MIC80's of CDTR against S. aureus, S. pneumoniae, S. pyogenes, H. influenzae, H. parainfluenzae and B. catarrhalis were 1.56, 0.39, < or = 0.025, < or = 0.025, 0.05 and 0.20 micrograms/ml, respectively. These results showed that CDTR has high antibacterial activities against these organisms. 2. Absorption and excretion: Serum concentrations and urinary recovery rates of CDTR-PI (administered in granules) were determined. Upon single oral doses of 3 mg/kg and 6 mg/kg, the peak serum concentrations were 0.5-2.45 micrograms/ml at 2 to 4 hours and 1.79-4.05 micrograms/ml at 1 to 4 hours, respectively, and T 1/2 was 1.07-9.67 hours and 0.99-3.00 hours, respectively. At 8 hours after dosing, serum concentrations were 0-0.87 micrograms/ml with a dose of 3 mg/kg and 0.27-0.73 micrograms/ml with 6 mg/kg. These values indicated that the drug has a dose-dependent pharmacokinetic behavior. Urinary recovery rates in the first 8 hours were 12.9-34.2% with a dose of 3 mg/kg and 11.8-26.9% with 6 mg/kg. 3. Clinical study: Clinical efficacies were examined in a total of 81 cases consisting of 20 cases of acute bronchitis, 13 of acute pneumonia, 21 of tonsillitis, 5 of pharyngitis, 7 of scarlet fever, 2 each of impetigo, otitis media and purulent cervical lymphadenitis, 1 of pertussis and 8 of UTI. The clinical efficacy rate was 97.5% (79/81), and bacteriological eradication rate was 100% (76/76). As for side effects, 2 cases of watery stools and 1 case of minor elevation of GPT were observed.
