1. Cefuroxime (CXM) was studied for absorption and excretion in 4 pediatric patients given one shot intravenous injection of 20 approximately 25 mg/kg. The following serum levels were determined: 24.5 approximately 38.0 micrograms/ml at 30 minutes (mean 33.3 +/- 6.1 micrograms/ml), 10.0 approximately 17.0 micrograms/ml at 1 hours (mean 13.9 +/- 3.3 micrograms/ml), 3.4 approximately 7.6 micrograms/ml at 2 hours (mean 5.2 +/- 1.9 micrograms/ml, 0.7 approximately 2.1 micrograms/ml at 4 hours (mean 1.3 +/- 0.6 micrograms/ml, 0.1 approximately 0.3 microgram/ml at 6 hours (mean 0.2 +/- 0.1 microgram microgram/ml). Half-life (
T 1
/2) was 0.65 approximately 0.88 hour (mean 0.75 +/- 0.10 hour). Urinary levels were 1,280 approximately 7,100 micrograms/ml at 0 approximately 2 hours, 96 approximately 3,400 micrograms/ml at 2 approximately 4 hours, 68 approximately 250 micrograms/ml at 4 approximately 6 hours. Urinary recovery rate at 0 approximately 6 hours was 54.1 approximately 74.4% (mean 61.8 +/- 9.4%). 2. From the study on spinal fluid concentration in pediatric patients with Haemophilus influenzae-induced meningitis, the dose of CXM 52.2 mg/kg was given to 1 pediatric case with this disease by one shot intravenous injection. Spinal fluid levels were presumed as 9.0 micrograms/ml at 30 minutes, 6.8 micrograms/ml at 1 hour, 3.8 micrograms/ml at 2 hours and 1.2 micrograms/ml at 4 hours. 3. CXM was studied in 19 pediatric patients with bacterial infection for clinical efficacy, bacteriological effect and side effect. Clinical result was found good in 1 with purulent meningitis; excellent in 9 out of 15 with acute lobar pneumonia or acute bronchopneumonia, and good in remaining 6 cases; good in 2 with acute bronchitis; excellent in 1 with acute pyelonephritis. This represents efficacy ("excellent" plus "good") rate of 100%. Of 5 strains of H. influenzae presumed as causative organisms, 4 were disappeared and 1 was reduced. Two strains of Streptococcus pneumoniae and 1 strain of Escherichia coli were disappeared. No side effect was noted in terms of clinical symptom. Laboratory examination showed elevation of GOT and
GPT
in 1 case, but these elevated values returned to normal after the end of the CXM treatment.

PC-904 was administered to 16 pediatric patients and the following basic and clinical results were obtained. (1) PC-904 was administered 20 approximately 30 mg/kg. The serum peak level of PC-904 after drip intravenous infusion over 1 hour was 66.7 microgram/ml at 1 hour and
T 1
/2 of PC-904 was 67.8 minutes. PC-904 was administered 25 approximately 30 mg/kg intravenous one shot injection was 49.4 microgram/ml at 1 hour and
T 1
/2 of PC-904 was 52.2 minutes. (2) Urinary excretion rate was about 20% up to 6 hours after drip intravenous infusion of 20 mg/kg. In a case of intravenous one shot injection of 25 approximately 30 mg/kg, the excretion rate was 11.9 approximately 19.9%. (3) PC-904 was administered 60 approximately 120 mg/kg/day for 3 approximately 48 days to 5 cases of sepsis and bacterial endocarditis, 6 of pneumonia, 2 of sss syndrome (staphylococcal scald skin syndrome) and 3 of pyelonephritis. Clinical effects were excellent in 11 cases and good in 5 cases, effective ratio being 100%. (4) Pseudomonas aeruginosa, Staphylococcus epidermidis, Streptococcus viridans, Acinetobacter anitratus and Hemophilus influenzae isolated from clinical specimens disappeared by the treatment of PC-904, and Hemophilus influenzae isolated from clinical specimens disappeared by the treatment of PC-904. Escherichia coli and Klebsiella pneumoniae reduced. (5) As to the side effect by PC-904, s-GOT and s-
GPT
were elevated in 2 cases. Anemia, rash and fever were observed in each 1 case out of 16 patients though the causal relation with the agent was unknown.

Therapeutic effects of cefprozil (CFPZ, BMY-28100), a new cephalosporin, were examined in various infectious diseases in children. Clinical efficacy rates were 50% (2/4) in acute bronchitis, 80% (4/5) in pharyngitis, 0% in laryngitis, 100% (7/7) in tonsillitis, 100% (8/8) in impetigo contagiosa, furuncle and posthitis. Hence, the overall efficacy rate was 84% (21/25). Adverse effects were observed in 1 case with slightly elevated serum GOT and
GPT
. Changes in serum concentrations and urinary excretion of CFPZ were examined in 4 and 2 children without infection, respectively.
T 1
/2 values obtained were between 1 hour to 2 hours (bioassay). Six hour recovery rates in urine were 51.8% and 77.8% (bioassay). CFPZ was considered to be a safe and useful drug in treating various infectious diseases in children.

Panipenem/betamipron (PAPM/BP), a mixture of a newly synthesized carbapenem antibiotic panipenem (PAPM) and N-benzoyl-beta-alanine, betamipron (BP), was evaluated for pharmacokinetics, in vivo and in vitro antimicrobial effect, and clinical efficacy in pediatric patients. Intravenous drip infusion of either 10 mg/10 mg/kg or 20 mg/20 mg/kg of PAPM/BP for 30 minutes resulted in maximum plasma concentrations of 36.6 micrograms/ml and 92.5 micrograms/ml, half lives (
T 1
/2 beta) of 1.17 hours and 0.88 hours, and urinary excretion until 6 hours of 29% and 17.7%, respectively. Antibacterial activities of PAPM against Gram-positive cocci and Gram-negative rods isolated from pediatric patients were equal to or slightly stronger than those of imipenem, ceftazidime, cefoperazone, and piperacillin. Clinical effects of PAPM/BP evaluated in 17 patients were as follows; excellent in 8 cases, good in 8 cases, and fair in 1 case. The overall efficacy rate was 94.1%. Elevations of GOT and/or
GPT
were observed in 2 patients and transient eosinophilia was observed in 1 patient.

Pharmacokinetic and clinical studies of flomoxef (FMOX) in neonates and premature infants were conducted, and the results obtained are summarized below. 1. Plasma concentrations of FMOX at 15 minutes after one shot intravenous injection of 20 mg/kg to 6 cases were in a rang of 33.0-69.9 micrograms/ml and half-lives (
T 1
/2's) were between 0.68 and 4.89 hours. The plasma concentration of FMOX at 15 minutes after one shot intravenous injection of 40 mg/kg to 1 case was 79.9 micrograms/ml and the half-life (
T 1
/2) was 2.45 hours. Drug concentrations in plasma upon 1-hour intravenous drip infusion were 71.1-114.0 micrograms/ml and
T 1
/2's were 1.64-3.41 hours.
T 1
/2 tended to be couse shorter as ages of babies increased. 2. Urinary excretion rates in the first 6 hours after one shot intravenous injection of FMOX 20 mg/kg to 1 case and 1-hour intravenous drip infusion of FMOX 40 mg/kg to 2 cases were 60.4%, and 27.2 and 55.3%, respectively. 3. Clinical effects of FMOX against 12 cases of bacterial infections were excellent in 6 cases, good in 5 cases and poor in 1 case, thus the clinical efficacy rate was 91.7%. FMOX was also given to 6 cases for prophylaxis and prophylactic effects were observed in all the cases. 4. No adverse effects were observed in the 21 cases examined, but elevations of S-GOT and S-
GPT
were found in 1 case. The abnormal laboratory test results were probably due to this drug.

Laboratory and clinical studies on cefpirome (CPR, HR 810), a newly developed cephem antibiotic, were performed. The results obtained are summarized as follows: 1. Absorption and elimination of the drug were examined in a total of 7 children including 3 cases of administered with 20 mg/kg intravenous bolus injection (i.v.), 2 cases with 20 mg/kg drip infusion (d.i.v.) for 60 minutes and 2 cases with 40 mg/kg (d.i.v.) for 60 minutes. Maximum serum levels were attained immediately after i.v. or d.i.v. Cmax's were 233 +/- 7.6, 88.5 +/- 14.5, and 116 +/- 15 micrograms/ml, respectively for the above 3 modes of administration. These values were determined using a bioassay method with Bacillus subtilis ATCC 6633.
T 1
/2 (beta)'s were 1.18 +/- 0.17, 1.61 +/- 0.28 and 2.68 +/- 0.83 hours, respectively. Cumulative urinary recovery rates were 40.2-69.8% in a period of 0-6 hours after admissions. 2. Clinical efficacies were evaluated in a total of 20 patients with ages ranging from 9 months to 11 years. The treated cases were 6 cases of acute pneumonia, 4 cases of acute bronchitis, 4 cases of acute purulent tonsillitis, 2 cases of acute urinary tract infections, 2 cases of cellulitis, 1 case of purulent lympadenitis and 1 case of acute otitis media. The clinical efficacy rate was 94.7%. Adverse reactions occurred in no patients. Abnormal changes in laboratory test values involved only 1 case with elevated GOT and
GPT
. CPR was considered to be a safe and useful drug in treating various infectious diseases in children.

A new injectable cephem antibiotic, cefpirome (CPR), was evaluated clinically in children. CPR was effective in all the 17 evaluable cases with acute bacterial infections including 1 case of purulent meningitis due to Haemophilus influenzae type b. Diarrhea and elevation of serum GOT and
GPT
were associated with CPR therapy in 2 young infants, although they were mild and transient. The plasma
T 1
/2 beta of CPR was 1.17 +/- 0.22 hours after bolus injection and mostly excreted in 6 to 8 hours into urine of children with normal renal functions. The data indicate that CPR is safe and effective, when used in children with susceptible bacterial infections.

Cefpirome (CPR, HR 810), a new parenteral cephalosporin antibiotic, was studied for its pharmacokinetics, bacteriological and clinical effects in the field of pediatrics. 1. CPR was very active against Staphylococcus aureus, Staphylococcus epidermidis, Coagulase-negative staphylococci, Streptococcus pneumoniae among Gram-positive cocci. Antibacterial activities of CPR were also strong against Branhamella catarrhalis, Haemophilus influenzae, Escherichia coli, Salmonella sp., Klebsiella oxytoca, Enterobacter cloacae, Pseudomonas aeruginosa among Gram-negative rods. 2. The plasma concentration 15 minutes after a bolus intravenous injection of 20 mg/kg was 80.4 micrograms/ml, and the
T 1
/2 (beta) was 1.03 hours. Plasma concentrations after intravenous drip infusion over 30 minutes of 20 mg/kg and 25 mg/kg were 48.3 and 117 micrograms/ml at the end of infusion, and
T 1
/2 (beta) for these dosage were 1.14 and 1.45 hours. 3. The urinary recovery rates over 6 hours after administration were 45.2-63.9% for CPR. 4. Clinical efficacies of CPR were excellent in 31 patients and good in 30 patients with an efficacy rate of 98.4%. In bacteriological examinations, causative organisms were eradicated with an eradication rate of 95.7%. 5. As side effects, diarrhea was observed in 5 patients and loose stool in 1 patient with an incidence of 8.2%. Abnormal values were found in some patients in clinical laboratory tests for eosinophilia, thrombocytosis and an elevation of GOT,
GPT
and triglyceride. These findings indicate that CPR will be useful against bacterial infections in pediatrics.

Pharmacokinetics and clinical studies on an injectable monobactam antibiotic aztreonam (AZT), were carried out in perinatal infections in obstetrics and gynecology and the obtained results are summarized as follows. 1. Pharmacokinetic study (1) Upon one-shot intravenous injection of AZT 1 g before delivery, maternal serum concentration of AZT was 89.0 micrograms/ml immediately after the injection and a half-life (
T 1
/2) of 0.96 hour was observed. Umbilical-cord serum concentration showed a peak value of 16.5 micrograms/ml at 1.26 hours after the injection and gradually decreased with a
T 1
/2 of 1.91 hours. The transfer into amniotic fluid was observed and the peak value of AZT in amniotic fluid reached 12.9 micrograms/ml at 5.57 hours after the injection and slowly decreased thereafter with a
T 1
/2 of 4.42 hours. Transfer and disappearance in one-shot 2 g intravenous injection and 1 g intravenous drip infusion (1 hour) of AZT were very similar to the results obtained with the one-shot 1 g intravenous injection. (2) The residual serum concentration in neonates after one-shot 1 g intravenous injection of AZT to the mother was almost below the detectable limit. Transfer of AZT into milk was scarcely recognized. 2. Clinical studies (1) AZT was injected to 47 cases with various perinatal infections and it was more than "effective" in 45 cases with an efficacy rate of 95.7%. Also, all the 12 cases to which AZT was administered for prophylaxis of infections showed prophylactic effect. Bacterial eradication was obtained with 25 strains out of 29 aerobic Gram-negative bacteria, but 1 strain "persisted" and for 3 strains results were "unknown", hence an eradication rate of 96.2% was obtained. However, AZT treatment resulted in a little lower eradication rate against Gram-positive bacteria. (2) One case (1.3%) of minor degree of urticaria was found as a side effect, and one case each of eosinophilia and elevation of GOT,
GPT
and Al-P was observed as abnormal laboratory value. From the above results of pharmacokinetics and clinical evaluation, it has been concluded that AZT is a useful and highly safe drug in various perinatal infections and prophylaxis.

Absorption and excretion of aztreonam (AZT) in neonates were studied and its clinical evaluation in 10 cases of neonates was performed using 1 hour intravenous drip infusion. 1. Serum concentrations of AZT in 7 neonates younger than 11 days of age were lower than those in infants. 2. Serum concentrations of AZT in 5 neonates given 20 mg/kg reached their peaks at the end of intravenous drip infusion with an average value of 45.8 +/- 10.41 micrograms/ml, and
T 1
/2 was 2.77 +/- 0.32 hours on the average. 3. Serum concentrations of AZT in 2 neonates given AZT 25 mg/kg reached their peaks at the end of intravenous drip infusion at 31.1 and 33.4 micrograms/ml with little difference from the 20 mg/kg group. Half-lives of serum AZT in the 2 cases were 1.87 hours and 3.23 hours, respectively. 4. Urinary excretion rates of AZT in 7 neonates younger than 11 days of age in the first 6 to 8 hours after the administration were 18.8 to 50.0%, or 31.7% on the average, which was lower than the average excretion rate found with infants. 5. All the cases given AZT showed clinical results rated better than "effective". Effect of AZT was excellent on 3 UTI cases caused by Escherichia coli and Klebsiella pneumoniae, but bacterial replacement (superinfection) of Enterococcus faecalis was observed when AZT was administered. 6. Transient elevations of GOT and
GPT
were seen in 2 cases when AZT administration was continued at length. Clinical side effect was not observed. 7. The most appropriate dosage and administration scheme of AZT against Gram-negative infections in neonates seems to be 40-60 mg/kg/day, b.i.d. or t.i.d.
