Pharmacokinetic and clinical evaluations of rokitamycin (RKM, TMS-19-Q), a new macrolide antibiotic, were carried out. RKM was administered orally to 14 patients with congenital heart diseases before cardiocatheterization and angiography. Peak plasma levels of RKM were observed at 30 minutes after the administration at dosages of 5, 10, 15 mg/kg. Although the reason is not clear, there were great variations among plasma levels. Peak plasma levels of patients with relatively good absorption were high enough against bacteria such as beta-hemolytic Streptococcus, Mycoplasma pneumoniae and Chlamydia trachomatis. Clinical responses were evaluated in 5 children comprising 2 cases of mycoplasmal pneumonia, 2 cases of Chlamydia infection and 1 case of beta-hemolytic streptococcal tonsillitis. All of these cases had excellent or good responses without any side effect. Furthermore, no child refused to take RKM dry syrup.

A newly developed cephalosporin, cefixime (CFIX), was evaluated clinically in 35 pediatric patients. A pharmacokinetic study was also performed with 11 patients. CFIX was administered as granules. The pharmacokinetic study was conducted in 11 patients, each of 6 patients was given CFIX at a dose of 3 mg/kg and each of the remaining patients was given CFIX at 6 mg/kg. Serum concentrations of CFIX were measured at 2, 4, 6, 8 and 12 hours after dosing. Urinary concentrations of CFIX were measured for periods of 0-6 and 6-12 hours after dosing. CFIX was assayed by the disk method using E. coli ATCC 39188 as the test organism. The clinical evaluation was conducted in 35 children including 5 patients of acute tonsillitis, 10 of acute lacunar tonsillitis, 1 of purulent lymphadenitis, 1 of scarlet fever, 8 of acute bronchitis, 5 of pneumonia, 3 of urinary tract infections and 1 of paratyphoid B. One additional patient was included only in the evaluation of safety since he was suffering from Mycoplasma pneumonia. the patients were from 4 months to 8 years 2 months old and 11 of them were inpatients. Daily doses were from 6.0 to 13.5 mg/kg. After CFIX administration in doses of 3 mg/kg and 6 mg/kg, peak serum concentrations were 1.75 and 3.36 micrograms/ml, half-lives were 2.65 and 2.86 hours and urinary excretions rates up to 12 hours after dosing were 16.1 and 12.4%, respectively. Serum concentrations were dose dependent and the half-life was fairly long compared with other known oral cephalosporins. Clinical efficacies of CFIX in 34 patients were "excellent" in 25 children, "good" in 8 and "poor" in 1 with effectiveness rate of 97.1%. Twenty-two strains of causative organisms, including 6 strains of S. aureus, 3 of S. pyogenes, 2 of S. pneumoniae, 3 of E. coli, 5 of H. influenzae, 2 of H. parainfluenzae and 1 of S. paratyphi B, were isolated. After treatment all strains except 2 strains of S. aureus (one was unknown and the other was decreased), 1 strain of S. pneumoniae (unknown) and 1 strain of H. influenzae (unknown) were successfully eradicated but S. paratyphi B was proved again in feces 9 days after treatment. No adverse reaction was observed. Among 18 children who went through laboratory test, however, an elevation of eosinophile and elevations of GOT and GPT were observed in 2 children and 1 child, respectively.

Bacteriological, pharmacokinetic, and clinical studies of cefixime (CFIX), a newly developed oral cephalosporin, was conducted in our pediatric department as outlined below. Bacteriology The prevalent MICs of CFIX by microbiological species, compared with those of the reference drugs, were detailed below. Against 16 strains of S. aureus, the MICs averaged 6.25 micrograms/ml, and were found to be nearly the same as the MICs of amoxicillin (AMPC) but higher than those of cephalexin (CEX) and cefaclor (CCL). For 4 strains of S. pyogenes, the MICs averaged 0.05 microgram/ml, and were higher than the MICs of AMPC but lower than those of CEX and CCL. Mean MICs of CFIX against other clinical isolates were lower than those of CEX, CCL, or AMPC; E. coli (20 strains), 3.13 micrograms/ml; K. pneumoniae (9), 0.10 microgram/ml; P. mirabilis (16), 0.025 microgram/ml; P. vulgaris (5), 0.10 microgram/ml; H. influenzae (11), 0.05 microgram/ml; and S. typhimurium (4), 0.10 microgram/ml. The MICs of CFIX against 10 strains of P. aeruginosa were distributed at and above 25 micrograms/ml, a range much lower than greater than or equal to 100 micrograms/ml for CEX, CCL, or AMPC. Pharmacokinetics The serum concentrations and urinary recovery were studied in 3 children ranging from age 7 to 13. They were given CFIX on empty stomach in 2 different single doses of 3 and 6 mg/kg in a cross-over design. Average serum CFIX concentrations were dose-dependent, as evidenced by the respective peak concentrations of 1.70 microgram/ml for a 3 mg/kg dosage and 2.72 micrograms/ml for 6 mg/kg, which were attained 4 hours after the administration of the drug. The average half-lives of CFIX in the serum were 3.09 hours and 3.11 hours, respectively, and the 12-hour serum concentrations were 0.32 microgram/ml and 0.77 microgram/ml, respectively, for the 2 different dose levels. The average 12-hour urinary recovery was 25.2% and 22.3%, respectively. Clinical study Clinical effectiveness, bacteriological effectiveness, and side effects were studied in 27 children with infection including 4 patients with acute pharyngitis, 13 with acute purulent tonsillitis, 5 with acute pneumonia, 3 with urinary tract infection, and 1 each with acute rhinitis and acute bronchitis. One child with acute pneumonia (Mycoplasma pneumonia) was excluded from the study. The therapeutic effectiveness was "excellent" in 21, "good" in 3, "fair" in 1, and "poor" in 1, with an effectiveness rate of 92.3%.(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.

A new antibiotic of cephamycin group, cefminox (CMNX, MT-141) was studied both fundamentally and clinically in the field of pediatrics. The minimum inhibitory concentrations (MIC) of CMNX for clinical isolates including 24 strains of S. aureus, 15 strains of S. pyogenes, 21 strains of H. influenzae, 24 strains of E. coli, 22 strains of K. pneumoniae and 22 strains of P. mirabilis were determined and compared to those of cefmetazole (CMZ), latamoxef (LMOX), cefotaxime (CTX), cefoperazone (CPZ) and cefazolin (CEZ). The MIC80 (80% MIC) values of CMNX for H. influenzae, E. coli, K. pneumoniae and P. mirabilis were 1.56, 1.56, 0.39 and 1.56 micrograms/ml, respectively. When compared to antibacterial activities of the control drugs, the activity of CMNX was inferior to those of CTX and LMOX but superior to those of CMZ and CEZ. On the other hand, MIC80 values of CMNX for S. pyogenes and S. aureus were 6.25 and 12.5 micrograms/ml, the activities being inferior to all of CMZ, CTX, LMOX, CPZ and CEZ used as the control drugs. In 3 pediatric patients of 9 to 12 years old, 20 mg/kg of CMNX was given intravenously as one shot and serum and urinary concentrations were determined. The mean serum concentrations in these 3 cases were 124 micrograms/ml, 102 micrograms/ml, 74.0 micrograms/ml, 47.9 micrograms/ml, 20.4 micrograms/ml, 9.2 micrograms/ml and 4.3 micrograms/ml at 1/4, 1/2, 1, 2, 4, 6 and 8 hours, respectively, with a half-life of 1.83 hours. The mean urinary concentrations were 1,968 micrograms/ml at 0 approximately 2 hours, 1,205 micrograms/ml at 2 approximately 4 hours, 761 micrograms/ml at 4 approximately 6 hours and 409 micrograms/ml at 6 approximately 8 hours, with 65.4% of the drug dosed recovered from the urine within the first 8 hours on an average. CMNX was used in the treatment of 22 clinical cases including 3 cases of acute purulent tonsillitis, 3 cases of acute bronchitis, 9 cases of acute pneumonia, 5 cases of acute pyelonephritis and 2 cases of acute enteritis. Clinical results in 20 cases excluded of 2 cases of Mycoplasma pneumonia were rated as excellent in 19 cases and as good in 1 case, with an efficacy rate being 100% taking excellent and good cases as effective cases. Bacteriological results for 5 strains of H. influenzae, 1 strain of H. parainfluenzae, 5 strains of E. coli, 2 strains of K. oxytoca and 1 strain of S. pneumoniae revealed that disappearance was obtained for all strains but 1 strain of P. aeruginosa which persisted.(ABSTRACT TRUNCATED AT 400 WORDS)

A clinical and laboratory evaluation and a blood level studied on aspoxicillin (ASPC), a new injectable penicillin derivative; the following results were obtained. ASPC was intravenously administered in 3 or 4 divided doses at a daily dosage ranging from 83.3 to 111.9 mg/kg to 5 patients (1 case of lacunar tonsillitis caused by H. influenzae, 3 cases of pneumonia caused by H. influenzae, 1 case of pneumonia caused by E. coli). As the results, a global effect were excellent in 3 cases and good in 2 cases. The overall efficacy ratio was 100%. All isolated organisms were eradicated, excluding the only case of pneumonia due to H. influenzae infection. No side effects were found in any of the 7 patients including 2 patients who were dropped out the efficacy evaluation because of Mycoplasma pneumonia. Laboratory findings showed a slight elevation of GOT and GPT in 2 cases and temporary eosinophilia in 1 case. Blood level of ASPC in 2 cases after 10 mg/kg administration by intravenous injection was 28.5 or 35.5 micrograms/ml at 30 minutes, 14.3 or 20.7 micrograms/ml at 1 hour, 6.1 or 8.8 micrograms/ml at 2 hours, 1.3 or 3.02 micrograms/ml at 4 hours. The half-life was 0.81 or 1.01 hours, respectively. Judging from the results of this blood level and the MIC of ASPC against clinically isolated organisms, good efficacy will be obtained to pediatric infections by the sensitive strains, if it is given 10 mg/kg to mild patients or 20 mg/kg to moderate or severe patients in 3 or 4 divided dose at a daily dosage.

9, 3"-Diacetylmidecamycin (MOM), a new macrolide antibiotic, was administered to 28 patients: 6 with pharyngitis caused by Group A beta-Streptococcus, 2 with lacunar tonsillitis, 8 with upper respiratory tract infection, 6 with acute bronchitis, 3 with Mycoplasma pneumonia, 1 with primary atypical pneumonia, 1 with pneumonia caused by H. influenzae and 1 with whooping cough. MOM in the form of fine granules was administered at a daily dose of about 20-30 mg/kg divided into 3 doses. Isolated group A beta-Streptococcus strains were eradicated in only 1 out of 6 strain S. One strain of H. influenzae was eradicated. The clinical results could be obtained with 21 cases and the response was excellent in 1 case, good in 7, fair in 3 and poor in 10. Although diarrhea was found in 3 cases during the administration of MOM, it was not clear whether these phenomena were caused by MOM, because of the prevalence of diarrhea among the children treated by us at that time.

Clinical efficacy of cefroxadine dry syrup, a new oral cephalosporin antibiotic, was evaluated in children, and the following results were obtained. 1. Three children were given a single oral dose of about 10 mg/kg of the drug when fasting, and its blood concentrations were determined. Blood concentrations were maximum at 30 approximately 60 minutes, i.e., 16.9 approximately 18.2 microgram/ml, and markedly low at 4 hours. 2. Thirty-six patients with the following diseases were tested with 23.1 approximately 44.4 mg/kg/day of the drug in 3 to 4 divided doses; 21 patients with lacunar tonsillitis, 2 with tonsillitis, 1 with scarlet fever, 4 with bronchitis and tonsillitis, 2 with cystitis, 4 with pyelonephritis, 1 with impetigo and 1 with probable Mycoplasma pneumonia. An overall efficacy rate in 35 patients excluding the last mentioned case was 91.4%, i.e., excellent in 20, good in 12 and poor in 3, and an eradication rate of the causative organisms was 88.9%. 3. Adverse reactions noted were diarrhea in 1 patient, eruption and diarrhea in 1 transient neutropenia in 1, eosinophilia in 3 and an elevation of GOT and GPT in 1. None were significant. 4. Taste and flavor of the drug was considered to be well palatable to children. 5. Taking into consideration of the results of fundamental evaluation of the drug, cefroxadine dry syrup is considered to be a potent new antibiotic in children, and the recommended dose will be 10 mg/kg 3 to 4 times a day.

Biapenem (L-627) was given intravenously to 17 children with acute bacterial infections including 3 with purulent tonsillitis, 1 with bronchitis, 4 with pneumonia, 2 with sepsis, 3 with pyelonephritis, 2 with SSSS. (2 cases are omitted from evaluation because of Mycoplasma pneumonia and infectious mononucleosis). Daily dosages per kg bodyweight ranging from 18.3 to 60 mg were given in 3 divided doses per day for 4 to 6 days. Clinical responses were excellent in 12 (80%), good in 2 (13.3%), fair in 1 (6.7%) and poor in 0 (0%), with an overall efficacy rate of 93.3%. Good bacteriological responses were obtained in all of the 9 cases from which pathogens were identified. A side effect is observed in only 1 case with mild diarrhea. The above results suggest that L-627 is a useful new carbapenem derivative for the treatment of bacterial infections in children.

Azithromycin (AZM), a new macrolide antibiotic, in fine granules and in capsules was studied for pharmacokinetic and clinical evaluation in the pediatric patients. Antibacterial activity of AZM against 43 clinical isolates: AZM exhibited slightly lower activity against Gram-positive bacteria and 2-8-fold higher activity against Gram-negative bacteria than erythromycin or clarithromycin. Plasma or urine samples were collected from eight patients receiving the drug in fine granular form, and two patients receiving it in capsules for the determination of drug levels. The elimination half-lives of AZM after administration at dose of 10 mg/kg/day for 3 days were 50.0 and 51.2 hours for fine granules, and 41.5 hours for capsules. AUC0-infinity was 11.7 and 24.3 micrograms.hr/ml for fine granules, and 8.3 micrograms.hr/ml for capsules. The cumulative excretion rates up to 120 hours after the start of treatment were 8.24 and 13.84% for fine granules, and 3.83% for capsules. AZM was administered to 123 patients once daily at 3.7-20.0 mg/kg body weight over 3 to 5 days with reference to the standard dose of 10 mg/kg. The drug was used to treat patients with pharyngitis, tonsillitis, scarlet fever, pneumonia, mycoplasmal pneumonia, chlamydial pneumonia, otitis media, pertussis, intestinal infection, and SSTI. The effectiveness of AZM was evaluated in 109 cases. The drug was rated "excellent" in 65.1% of the patients and "good" in 29.4%, resulting in an efficacy rate of 94.5%. Furthermore, AZM eradicated 43 of 46 (93.5%) bacteria that had been identified before the treatment. Three patients complained of side effects of urticaria (1 case) and diarrhea (2 cases). Abnormal laboratory changes were reported as follows: decreased leukocyte (3 cases), increased eosinophil (5), increased platelet (2), increased eosinophil and platelet, elevated GPT (1), and elevated GOT and GPT (1). The abnormalities, however, were mild enough to raise no clinically significant problems. In conclusion, AZM in once daily regimen was effective and safe in treatment of pediatric infections.
