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.

Laboratory and clinical studies on cefprozil (CFPZ, BMY-28100), a new cephem antibiotic, were carried out in the field of pediatrics. The results obtained are summarized as follows: 1. Serum concentrations, urinary concentrations and urinary recovery rates of CFPZ were determined upon oral administration of CFPZ after meal at doses of 4 mg/kg granules in a case, 7.5 mg/kg granules in 2 cases and 15 mg/kg granules in one. Peak serum levels of CFPZ were obtained at an hour in 3 cases and at 2 hours in 1 case after administration of the drug with a range of 2.7-8.6 micrograms/ml with half-lives of 0.69-0.95 hours. Urinary recovery rates in the first 6 hours after administration ranged from 59.4-71.3%. 2. MICs of CFPZ against 36 clinical isolates (Staphylococcus aureus 4 strains, Streptococcus pneumoniae 5, Streptococcus pyogenes 5, Escherichia coli 5, Haemophilus influenzae 12, Haemophilus parainfluenzae 4, and Branhamella catarrhalis 1) were compared with those of cefaclor (CCL) and ampicillin (ABPC). The antibacterial activity of CFPZ was superior to those of CCL against Gram-positive cocci, and to those of ABPC against E. coli, and was equal to those of CCL and inferior to those of ABPC against
H. influenzae
. 3. Thirty-seven pediatric patients with acute infectious diseases (pharyngitis/tonsillitis 17, bronchitis 7, pneumonia 3, skin and soft tissue infection 2, and urinary tract infection 8) were treated with CFPZ at daily doses of 10-47 mg/kg t.i.d. as a rule. The efficacy rates were 100% clinically and 56% bacteriologically. 4. Side effects or abnormal laboratory test values were not observed except for an increased platelet count in 1 case and elevated GOT,
GPT
values in 2 cases.

Bacteriological and clinical studies on cefodizime (CDZM, THR-221), a new cephem developed by Hoechst AG and Roussel Uclaf, were carried out and the results are summarized below: 1. Against Gram-positive bacteria, Staphylococcus aureus, Streptococcus pyogenes and Streptococcus pneumoniae, antibacterial activities of CDZM were similar to those of cefotaxime (CTX), cefazolin, cefotiam and piperacillin. Against Escherichia coli, Klebsiella pneumoniae and Serratia sp., antibacterial activities of CDZM were similar to that of CTX, and superior to those of other tested antibiotics. Especially against Haemophilus influenzae and Branhamella catarrhalis, it showed an excellent antibacterial activity. 2. Although the clinical efficacy was poor in 1 patient with sepsis caused by Salmonella marcescens and in another with cervical lymphadenitis, in 5 patients with upper respiratory tract infection, 4 patients with bronchitis, 6 patients with bronchopneumonia, 18 patients with pneumonia, 5 patients with urinary tract infection and 1 patient with enteritis, the clinical efficacy was excellent or good and the efficacy rate was 95.1% (39/41) including excellent efficacies in 25 cases. 3. Bacteriologically, all identified causative bacteria were eradicated except for 1 case of Salmonella sp., thus the eradication rate was 97.4% (38/39). Especially S. pneumoniae in 10 cases,
H. influenzae
in 12 cases and B. catarrhalis in 3 cases were eradicated totally. 4. Adverse reactions were studied in 46 cases, and digestive symptoms were observed in 9 cases (diarrhea 5 cases, loose stools 4 cases). Eruption and vascular pain were observed in 1 case each. As digestive symptoms in 9 cases were mild, the treatment were not suspended. In laboratory test values, elevation of GOT, elevation of
GPT
, elevation of bilirubin, and eosinophilia were observed in 1 case each. Influences on blood coagulation parameters were studied. No change was observed between the beginning and the end of the treatment. From above results, we have concluded that CDZM is a useful and safe antibiotic in pediatrics, administered at a daily dose of 20 mg/kg divided into 3 or 4 doses and administered intravenously.

Pharmacokinetic and clinical studies on sulbactam/ampicillin (SBT/ABPC) were carried out in the field of pediatrics. 1. Absorption and excretion Serum levels and urinary excretion of SBT/ABPC were studied in 4 children with ages 6 to 8 years. The mean serum concentration of SBT at 15 minutes following a single intravenous injection of 30 mg/kg of SBT/ABPC was 27.4 +/- 2.2 micrograms/ml and that of ABPC was 42.8 +/- 3.9 micrograms/ml, and their concentrations declined with mean half-lives of 1.06 +/- 0.15 hours and 0.84 +/- 0.05 hour, respectively, and at 6 hours were 0.3 +/- 0.2 microgram/ml and 0.2 +/- 0.1 microgram/ml on the average, respectively. The urinary recovery rates of SBT and ABPC at 6 hours after the injection were 59.0 +/- 22.4% and 58.4 +/- 25.3% on the average, respectively. 2. Clinical study SBT/ABPC was used for the treatment of a total of 36 pediatric patients with ages ranging 2 months to 11 years and it's clinical effectiveness, bacteriological efficacy and adverse effects were evaluated. Clinical efficacies in 5 patients with acute purulent tonsillitis, 26 with acute pneumonia and 1 with acute pyelonephritis were judged to be excellent in 27 cases and good in 5 cases with an overall efficacy ratio of 100.0%. Clinical efficacies in 6 patients whose infections were caused by beta-lactamase producing strains were judged to be excellent in all cases. Bacteriological efficacies of SBT/ABPC were assessed on 1 strain of Staphylococcus aureus (beta-lactamase producing strain), 2 strains of Streptococcus pneumoniae, 16 strains of Haemophilus influenzae (5 beta-lactamase producing strains and 11 non-beta-lactamase producing strains), 1 non-beta-lactamase strain of Haemophilus parainfluenzae and 2 strains of Escherichia coli (non-beta-lactamase producing strains). All strains except 1 strain of
H. influenzae
(beta-lactamase producing strain) which decreased in number were eradicated with a bacteriological eradication rate of 95.5%. Only 1 patient complained of diarrhea which was suspected to be related to the drug. No other side effect was reported. Elevations of GOT and
GPT
were observed in only 1 patient. The above results suggested that SBT/ABPC was a useful drug with preferable safety profile in the treatment for pediatric patients with infectious disease caused by beta-lactamase producing strains as well as those by non-beta-lactamase producing strains.

Pharmacokinetic, bacteriological and clinical studies on cefpodoxime proxetil (CPDX-PR, CS-807), a newly developed oral cephem, were carried out in the treatment of infectious diseases in the field of pediatrics. 1. Since CPDX demonstrates very powerful antimicrobial actions against such Gram-negative bacilli as Escherichia coli, Salmonella sp., Klebsiella pneumoniae and Serratia sp., such Gram-positive cocci as Streptococcus pyogenes and Streptococcus pneumoniae, and beta-lactamase producing Branhamella catarrhalis and Haemophilus influenzae, this drug was thought to be useful for the treatment of pediatric infectious diseases when main causative bacteria in the field of pediatrics were taken into account. 2. When changes in blood and urine concentrations of CPDX following the administration of this drug at 3.7 mg/kg before meal were determined, Cmax and T1/2 were found to be 2.98 micrograms/ml at 2-hour and 1.73 hours, respectively; an urinary excretion rate in the first 6 hours and a maximum urine concentration were 32.5% and 52 micrograms/ml, respectively. 3. Clinically, 8 of 8 patients with the upper respiratory tract infections (100%), 28 of 29 patients with bronchitis and/or pneumonia (96.6%), 3 of 4 patients with otitis media (75%), 2 of 2 patients with sinusitis (100%), 3 of 3 patients with the skin soft tissue infections (100%), 1 of 1 patient with bacterial enteritis (100%) and 11 of 14 patients with urinary tract infections (78.6%) responded well to the treatment with CPDX-PR, showing a 91.8% efficacy rate in all the patients treated. 4. Bacteriologically, Staphylococcus aureus, Staphylococcus epidermidis, S. pyogenes, S. pneumoniae, E. faecalis, B. catarrhalis,
H. influenzae
, E. coli and Salmonella typhimurium were all eradicated from 5, 1, 4, 6, 1, 5, 5, 11 and 1 patient, respectively. An eradication rate in all the patients examined was 97.5% (39/40). 5. Gastrointestinal symptoms appeared as side effects in 2 of 71 patients (vomiting in 1 and diarrhea in 1), hence, an incidence of side effects was 2.8% (2/71). As for abnormal laboratory findings, eosinophilia, thrombocytosis and increases in GOT and
GPT
were observed in 3 of 39 patients examined (7.7%), 1 of 39 patients (2.6%) and 2 of 34 patients (5.9%), respectively. In addition, we also examined the effect of the drug on the hemostatic system, but found no changes upon the treatment. Based on these results, it appeared that CPDX-PR was a useful and safe drug in treatment of infectious diseases in the field of pediatrics when administered 2-3 times a day at a dose of 3-6 mg/kg.

Clinical evaluation and kinetics in serum of cefoperazone (CPZ) in patients with lower respiratory tract infections have been conducted as a multicenter trial participated by 20 institutions in Kyushu area during a period of 8 months from October 1984 to May 1985. Mean serum CPZ levels up to 4 hours following the end of intravenous infusion of either 1 or 2 g CPZ remained higher than the MIC80 of CPZ against major causative organisms of lower respiratory tract infections such as
H. influenzae
, P. aeruginosa, K. pneumoniae, and S. pneumoniae. Serum half-lives of CPZ following intravenous infusion were prolonged in the elderly and in patients who showed moderate liver or kidney dysfunction, but did not exceed twofold of normal value. Clinical efficacy rates of CPZ were 82.9% (34/41) against pneumonia, 80% (4/5) against lung abscess, 88.9% (32/36) against acute exacerbation of chronic bronchitis, 66.7% (2/3) against panbronchiolitis, 100% (1/1) against acute bronchitis, and 85.7% (12/14), 64.3% (9/14) and 70.0% (7/10) against infections concurrent to chronic respiratory diseases, pulmonary emphysema and bronchiectasis, respectively. The overall efficacy rate was 81.5% (101/124). Bacteriological eradication rates against P. aeruginosa,
H. influenzae
and S. pneumoniae were 60% (6/10), 88.9% (8/9) and 100% (3/3), respectively. The overall eradication rate including polymicrobial infection was 67.5% (27/40). The clinical efficacy rate of CPZ in patients with underlying diseases such as lung cancer, pulmonary tuberculosis, and pneumoconiosis, etc. was not significantly different from the efficacy rate in patients without these underlying diseases. Of 20 patients who failed to respond to previous antibiotic treatments, 13 were effectively treated by CPZ. Adverse reactions occurred in 6.7% (11/164) of the patients, and consisted primarily of rash, fever, diarrhea and loose stool. Laboratory abnormalities were seen in 5 patients during the study. These included elevations of S-GOT and S-
GPT
, eosinophilia and neutropenia. CPZ is a very useful drug in the treatment of lower respiratory tract infections because of its excellent clinical efficacy and rare incidence of abnormal accumulations in sera following the recommended 2-4 g/day administration even in the elderly.

Fundamental and clinical studies on cefuzonam (L-105, CZON), a newly semisynthesized cephem antibiotic, were carried out in the field of pediatrics and the following results were obtained. Antibacterial activities of CZON against clinically isolated strains of Staphylococcus aureus, S. epidermidis, Streptococcus pneumoniae, S. pyogenes, Escherichia coli, Klebsiella pneumoniae, Haemophilus parainfluenzae and
H. influenzae
were compared with those of cefmenoxime (CMX), latamoxef (LMOX), cefoperazone (CPZ), cefmetazole (CMZ), cefotiam (CTM) and cefazolin (CEZ). CZON was nearly as active as CEZ against S. aureus and S. epidermidis and superior to other antibiotics against other Gram-positive cocci. Against Gram-negative rods, CZON was as active as CMX and superior to other 5 antibiotics compared. Serum concentrations and urinary excretion rates after intravenous bolus injection of CZON at doses of 10 mg/kg, 20 mg/kg and 40 mg/kg for 5 minutes in 1, 5 and 4 cases, respectively, were determined. Mean serum concentrations of CZON at these dose levels were 11.0, 43.8 and 111.5 micrograms/ml at 15 minutes, 2.4, 10.3 and 30.3 micrograms/ml at 1 hour and 0.17, 0.72 and 1.28 micrograms/ml at 4 hours, with serum half-lives of 1.79, 0.88 and 1.19 hours, respectively. Mean cumulative urinary excretion rates within 6 hours after administration were 47.9, 56.3 and 40.3%, respectively. Thirty-four pediatric patients with various bacterial infections (tonsillitis 2, acute bronchitis 1, pneumonia 14, pyothorax 1, sepsis 1, suppurative lymphadenitis 1, UTI 13 and enteritis 1) were treated with CZON at a daily dose of 40-94 mg/kg t.i.d. or q.i.d.. The overall clinical efficacy rate was 94.1%. No adverse reactions were observed except 2 cases with mild diarrhea. Abnormal laboratory findings were also mild; slight elevation of GOT and
GPT
in 2, eosinophilia in 1 and thrombocytosis in 1. These results clearly indicate the usefulness of CZON in the treatment of bacterial infections in children.

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.

Fundamental and clinical studies on cefixime (CFIX), a new oral cephem antibiotic, were carried out in the pediatric field. The results were as follows: Serum concentrations and urinary recovery rates were determined after oral administration of CFIX at doses of 3 mg/kg and 6 mg/kg in 2 cases each (4 cases in total). The mean serum concentrations of CFIX were 0.52 and 0.58 micrograms/ml at 2 hours, 0.80 and 1.42 micrograms/ml at 4 hours, 0.73 and 1.36 micrograms/ml at 6 hours, 0.54 and 1.12 micrograms/ml at 8 hours, respectively. The mean peak serum concentration of CFIX was obtained at 4 hours after administration, with serum half-lives (T1/2) of 3.77 and 5.30 hours, respectively. The mean cumulative urinary recovery rates within 12 hours after administration of CFIX at doses of 3 mg/kg and 6 mg/kg were 8.4% and 6.8%, respectively. Antibacterial activities of CFIX against clinically isolated strains of S. pyogenes, S. pneumoniae. E. faecalis, S. aureus, E. coli,
H. influenzae
, H. parainfluenzae were compared with those of amoxicillin (AMPC), cefaclor (CCL), and cephalexin (CEX). It was observed that CFIX was a little less active than AMPC against S. pyogenes and S. pneumoniae, but CFIX was more active than CCL and CEX. CFIX was the most active against E. coli,
H. influenzae
and H. parainfluenzae. Twenty-one pediatric patients with bacterial infections (10, tonsillitis; 4, pharyngitis; and 7, urinary tract infections) were treated with CFIX at doses of 1.5-6.0 mg/kg in 2 or 3 times daily for 4-10 days. The efficacy rate was 95.2% clinically and 91.3% bacteriologically. No adverse reactions were observed. An abnormal laboratory finding (slight elevation of S-GOT and S-
GPT
) was observed in 1 case.

T-2588 was used on 55 patients with respiratory tract infections and 44 cases were evaluated; 23 patients with pneumonia, 12 patients with acute bronchitis, 2 patients with chronic bronchitis, 1 patient with diffuse panbronchiolitis and 6 patients with bronchiectasis with infection. Clinical effects of T-2588 were as follows; excellent in 6 and good in 28 patients. The efficacy rate was 77.3% (34/44). Bacteriological effects of T-2588 were prominent in 8 patients infected with B. catarrhalis,
H. influenzae
, K. pneumoniae and E. coli, but not in a patient infected with P. putida. The elimination rate was 90.0% (9/10 strains). As side effects, stomatitis, anorexia, diarrhea X vomiting and pruritus were observed in one patient each. Abnormal laboratory findings were observed in 4 patients with elevated GOT and/or
GPT
. These side effects and abnormal laboratory findings were not serious. The usefulness of T-2588 was 68.2% (30/44). Therefore, T-2588 is a useful drug and its effects are promising in clinical management of respiratory tract infections.
