PC-904 was administered to 24 patients: urinary tract infections (7 cases), bronchitis (2 cases), pneumonia (3 cases), brain abscess (1 case), septicemia and the suspected cases (10 cases), and buttock abscess (1 case). The daily dosage varied from 60 to 223.4 mg/kg and averaged 86.9 mg/kg. The drug was administered three times a day by 1-hour drip infusion, and the duration of the treatment averaged 11 days. Clinical results were obtained as excellent responses in 5 cases, good in 13, poor in 4, and unknown in 2, giving 75% of the clinical effectiveness. Bacteriological responses were excellent in 7, good in 2, poor in 2, and unknown in 13, and the overall effectiveness was evaluated as excellent in 2, good in 17, and unknown in 5. Antibacterial activities against clinically isolated bacteria were examined. MIC values of PC-904 were over 100 mg/ml 1 strain of E. coli and 2 strains of Klebsiella, however excellent sensitivities were observed in 3 strains of Ps. aeruginosa and MIC values varied 1.56 to 3.12 microgram/ml at 10(8) of inoculum size and 0.78 to 1.56 microgram/ml at 10(8). As to side effects, diarrhea was observed in 1 case, rash in 2, lowering ob blood pressure in 2, elevation of GOT in 1, and elevation of LDH in 2. Abnormal elevations of GOT (10 cases), GPT (5 cases), A1-P (1 case), LDH (7 cases), and BUN (1 case) were noticed in other patients, but it was considered to be due to underlying diseases.

Cefprozil (CFPZ), a newly developed oral cephalosporin in a fine granular form for pediatric use, was administered to children with bacterial infections. MICs were determined for 6 drugs including CFPZ, cephalexin (CEX), cefaclor (CCL), ampicillin (ABPC), methicillin (DMPPC) and cloxacillin (MCIPC) against the following 84 strains isolated from cases to which CFPZ was administered; 55 strains of Gram-positive cocci (GPC) including 2 strains of Staphylococcus aureus, 49 strains of Streptococcus pyogenes, 4 strains of Streptococcus pneumoniae, and 29 strains of Gram-negative bacilli (GNB) including 10 strains of Haemophilus influenzae, 18 strains of Escherichia coli, and 1 strain of Proteus mirabilis. MIC determination of these strains was done with an inoculum size of 10(6) CFU/ml. In pharmacokinetic studies, serum concentrations, urinary concentrations and urinary recovery rates were investigated using bioassay and high-performance liquid chromatography (HPLC). CFPZ was orally administered 30 minutes before meals to 9 children with ages ranging from 7 years and 1 month to 12 years and 3 months. Three groups of 3 children were tested with doses of 4.0, 7.5 and 15.0 mg/kg, respectively. In addition to the above, clinical and bacteriological studies were performed in a total of 160 cases consisting of children with ages ranging 5 months to 12 years and 5 months. A mean dose of 8.6 mg/kg in 3-4 divided doses (130 cases of t.i.d. and 30 cases of q.i.d.) was administered for an average of 7 days. The 160 cases included 34 cases of pharyngitis, 5 cases of tonsillitis, 8 cases of acute bronchitis, 8 cases of pneumonia, 52 cases of scarlet fever, 4 cases of acute purulent otitis media, 47 cases of urinary tract infection, 1 case of purulent lymphadenitis and 1 case of posthitis. Adverse reactions and abnormal clinical laboratory test results were also examined in 166 cases, including 6 cases excluded from the evaluation of clinical efficacy. The results obtained are summarized as follows: 1. With regard to GPC, MICs of CFPZ against 2 strains of S. aureus were 0.78 or 1.56 micrograms/ml and CFPZ showed the second highest activity to MCIPC. MICs of CFPZ against 49 strains of S. pyogenes were all less than 0.025 micrograms/ml.(ABSTRACT TRUNCATED AT 400 WORDS)

Cefdinir (CFDN), a newly developed oral cephalosporin in a 10% fine granular form, was administered to 8 children and concentrations of the drug in plasma and urine and urinary recovery rates of the drug were determined. The subjects were divided into 2 groups of 4 children each; one group received 3 mg/kg of CFDN at 1 hour before meal (in the fasting state), and the other, at 30 minutes after meal. To study clinical and bacteriological effects of this drug, a mean dose of 4.8 mg/kg t.i.d. was administered for 8 days on the average to 9 children with various infections; tonsillitis (3 cases), acute bronchitis (1), pneumonia (1), acute purulent otitis media (1), urinary tract infection (2), and impetigo (1). MICs were determined for 6 drugs including CFDN, cefaclor, cefixime (CFIX), methicillin, cloxacillin, amoxicillin (AMPC) against 4 strains 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 children. The results obtained are summarized as follows. 1. Mean plasma peak levels of CFDN were observed at 2 hours after administration in the before-meal group and 4 or 5 hours after administration in the after-meal group mean peak values of 0.88 and 0.50 micrograms/ml, respectively. Mean half-lives were 1.61 hours in the before-meal group and 2.54 hours in the after-meal group, and mean AUCs were 4.24 in the former and 3.59 micrograms.hr/ml in the latter. 2. Mean urinary peak concentrations of CFDN were observed during 2-4 hours after dosing in the before-meal group and during 6-8 hours in the after-meal group with values of 93.3 and 44.8 micrograms/ml, respectively, in cases for which plasma concentrations of drugs were determined. Mean urinary recovery rates during the first 8 hours after administration in the before- and after-meal groups were 16.6 and 13.4%, respectively. 3. Good clinical effects were obtained with an efficacy rate of 100% in 9 patients with 6 diseases due to bacterial infections. 4. Good bacteriological effects were also obtained against 2 strains of Streptococcus pyogenes, 2 strains of Escherichia coli and 1 strain of Haemophilus influenzae with an eradication rate of 100%. In 3 cases of these and another case (normal flora), strains present before the study were replaced by other strains.(ABSTRACT TRUNCATED AT 400 WORDS)

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)

The pharmacokinetics, efficacy and safety of sulbactam/ampicillin (SBT/ABPC) were evaluated in 21 children with a variety of infections. The results obtained are summarized as follows. 1. Pharmacokinetics in 4 children, each receiving a single dose of 60 mg/kg, were evaluated. The average half-life of SBT was 1.03 hours and that of ABPC was 0.83 hour. 2. In vitro antimicrobiol activity (MIC) of SBT/ABPC in which SBT and ABPC are combined at a ratio of 1:2 was stronger than ABPC alone and was quite effective against Staphylococcus aureus and Haemophilus influenzae, but activity against Escherichia coli was relatively low. Antimicrobial activity of SBT/ABPC against S. aureus was almost equal to those of piperacillin (PIPC), cefazolin (CEZ) and cefmetazole (CMZ), but against H. influenzae was stronger than those of CEZ and CMZ. Activity against E. coli was lower than those of PIPC, CEZ and CMZ. 3. A total of 21 patients including 3 with pharyngitis, 10 with bronchitis, 5 with pneumonia, 1 each with acute enteritis, pyelonephritis and suspected sepsis were treated with SBT/ABPC. The clinical efficacy rate for these patients was 95.2% (20/21). The bacteriological eradication rate was 80% (8/10). 4. There were 4 instances of side effects, 1 case each of eruption, diarrhea, thrombocytosis and eosinophilia, but all symptoms were transient.

Four hundred and twenty two pneumococcal strains isolated from 300 patients with chronic nonspecific pneumonia and bronchitis were studied with respect to their sensitivity to 18 antibiotics within a period from 1982 to 1985. It was shown with the method of serial dilutions on solid media that 91.7, 87.8, 85 and 81 per cent of the isolates were sensitive to benzylpenicillin, ampicillin, lincomycin and cefuroxime, respectively. A significant percentage of the pneumococcal strains had decreased sensitivity to benzylpenicillin (MIC close to the therapeutic concentration). On this basis it was recommended to use lower concentrations of benzylpenicillin (less than 0.25 units/ml) in assay of sensitivity in clinical strains of Pneumococcus.

Cefodizime (THR-221, CDZM), a new parenteral cephalosporin, was evaluated for its efficacy and safety in 20 children with bacterial infections (Table 1), and the following results were obtained. 1. CDZM was administered in 3 or 4 divided doses at daily dosages ranging from 54.5 to 84.2 mg/kg administered by 30 minutes drip infusion or intravenous injection to 20 patients (7 cases of acute tonsillitis, 6 cases of pneumonia, 2 cases each of bronchitis and suppurative cervical lymphadenitis, and 1 case each of acute pharyngitis, acute enteritis and furunculosis) and the following clinical results were obtained: excellent, 7 cases; good, 11 cases; fair, 2 cases. The overall efficacy rate was 90% (Table 4). 2. MICs of CDZM against 15 strains of isolated organisms are shown in Table 2. MICs against all 7 strains of Haemophilus influenzae were less than 0.025 micrograms/ml. MIC against 1 out of 5 strains of Streptococcus pneumoniae was 0.05 micrograms/ml and those against 2 strains were 0.10 micrograms/ml and against the other 2 were 0.20 micrograms/ml. MICs against 3 strains of Staphylococcus aureus were 1.56, 25 and higher than 100 micrograms/ml, respectively. 3. No clinical adverse reaction was observed in any of the 20 patients. Eosinophilia was observed in 2 cases. A slight elevation of S-GOT was found in 1 patient (case No. 8) and moderate elevation of S-GOT and S-GPT in another (case No. 18) (Table 4). In case No. 18, the S-GOT and S-GPT activity improved after the administration of the drug was stopped.(ABSTRACT TRUNCATED AT 250 WORDS)

Cefodizime (CDZM, THR-221), a new cephem antibiotic, was investigated for its clinical efficacy and pharmacokinetics in children. The results obtained are summarized as follows. 1. Antimicrobial activities Antimicrobial activities of CDZM against clinically isolated organisms were determined. MICs of CDZM against 1 strain each of Streptococcus pneumoniae, Escherichia coli and Klebsiella pneumoniae were 0.05 micrograms/ml to 0.10 micrograms/ml. Especially, MIC against all 6 strains of Haemophilus influenzae was less than or equal to 0.024 micrograms/ml. This MIC value was lower than those of other antibiotics such as cefotaxime, cefotiam, cefazolin, piperacillin. 2. Pharmacokinetics CDZM was given to 1 case at a dose of 20 mg/kg by a 60-minute intravenous drip infusion. The peak value of serum concentration of CDZM was 207.80 micrograms/ml at the end of the infusion. The half-life was 2.15 hours. The mean urinary excretion rate was 68.5% in the first 4 hours, 79.2% in 6 hours and 76.5% in 8 hours after the 30-minute drip infusion. 3. Clinical efficacy CDZM was given to a total of 27 patients, 13 with pneumonia, 1 with bronchitis, 2 with acute pharyngitis, 1 with purulent tonsillitis, 5 with urinary tract infection, 1 each with retrograde cholangitis, acute enteritis, pericementitis, phlegmon and inguinal lymphadenitis. Overall clinical efficacies were excellent in 5 cases, good in 17 and the efficacy rate was 81%. Bacteriological effects were investigated in 13 cases and the eradication rate was 85%. No adverse reactions were observed in any case. As abnormal laboratory findings, elevated GOT, GPT, A1-P, LAP and gamma-GTP, were noted in 1 out of the 28 cases examined.

Clinical studies were performed on cefodizime (THR-221, CDZM), a new cephem antibiotic as described below. CDZM was administered to 13 patients in dose levels ranging from 55 to 96 mg/kg/day t.i.d. for 3-7 days (5.5 days on average). These patients included 8 with pneumonia, 2 with tonsillitis, 1 each with bronchitis, phlegmon and urinary tract infection. The overall efficacy rate was 92.3%, i.e., efficacy was excellent in 8, good in 4 and poor in 1. Bacteriological efficacy was 83.3%, i.e., 5 strains of bacteria (Streptococcus pneumoniae 1, Haemophilus influenzae 3, Haemophilus parainfluenzae 1) were eradicated and 1 was unchanged (Enterobacter cloacae, MIC greater than 100 micrograms/ml). Clinical side effect was not observed during the treatment. Laboratory abnormalities were observed in 2 cases, i.e., a slight elevation of GPT and a mild eosinophilia. The above results suggest that CDZM is a useful antibiotic for treating pediatric bacterial infections.

Bacteriological, pharmacokinetic and clinical studies were done on the effect of cefteram pivoxil (CFTM-PI, T-2588) (10% granules), a new oral cephalosporin, in the field of pediatrics. The results are summarized below. 1. Antibacterial activities Antibacterial activities of CFTM against Staphylococcus aureus and Streptococcus pyogenes were studied comparatively with activities of cefaclor (CCL), cephalexin (CEX) and ampicillin (ABPC). MICs of CFTM against S. aureus were distributed in a range between 0.78 and 12.5 micrograms/ml, with a peak value of 3.13 micrograms/ml, which were similar to MIC ranges of CEX and CCL. MICs of CFTM against all strains of S. pyogenes were less than or equal to 0.025 microgram/ml, which were similar to MIC of ABPC. CFTM was approximately 2 to 3 folds more effective than CCL or CEX. 2. Absorption and excretion. Serum concentrations and urinary excretions of CFTM were determined in doses of 3 mg/kg (non-fasting) and 6 mg/kg (non-fasting and fasting). In non-fasting subjects, peak concentrations of CFTM in serum were dose-dependent and were 1.15-2.3 micrograms/ml and 1.8-3.6 micrograms/ml at 2-3 hours, 0.125-0.78 micrograms/ml and 0.245-0.97 micrograms/ml at 6 hours, respectively, for the 2 dose levels. Serum half-lives were 1.03-2.65 hours for the dose of 3 mg/kg and 1.07-1.83 hours for 6 mg/kg. In fasting subjects, the mean peak serum concentrations were 1.73 micrograms/ml at 2 hours and 1.13 micrograms/ml at 6 hours for the dose of 6 mg/kg. Urinary recovery rates in the first 6 hours varied 5.3-19.2%. 3. Clinical study Clinical efficacies were examined in a total of 41 cases including 9 cases of bacterial pneumonia, 10 cases of bronchitis, 11 cases of tonsillitis, 7 cases of urinary tract infections, 3 cases of scarlet fever and 1 case of otitis media. Clinical efficacies were excellent in 30 cases, good in 10 cases, poor in 1 case, hence the efficacy rate was 97.6%. All of the 28 bacteria identified in these cases were eradicated after CFTM-PI treatments. No noticeable abnormalities were found as side effects. An elevation of eosinophil, an increase of platelet count and elevations of GOT and GPT were observed in 3 patients.
