Cefpirome (CPR, HR 810) was clinically evaluated for its efficacy and safety in 11 patients with ages from 4 months to 11 years with bacterial infection. The results obtained are summarized as follows. 1. CPR was administered to 6 patients with bronchopneumonia, a patient with pneumonia, a patient with tonsillitis, 2 patients with acute pharyngitis and a patient with suppurative parotitis at daily dosage levels ranging 55.5-91.7 mg/kg, divided into 3 using intravenous bolus injection or 30 minutes drip infusion. Clinical responses of the 11 patients were as follows: excellent; 8 patients, good; 2 patients, poor; 1 patient, hence the efficacy rate was 90.9%. 2. Neither clinical adverse reaction nor abnormal laboratory test value was observed except slight elevation of GOT and GPT in a patient and leukopenia in another. 3. MICs of CPR against 18 beta-lactamase producing strains isolated from patients were as follows. MIC against a strain of Staphylococcus aureus was 1.56 micrograms/ml, MICs against 3 strains of Klebsiella pneumoniae were less than 0.025 microgram/ml, those against 3 out of 5 strains of Enterobacter cloacae were less than 0.025 microgram/ml and those against the remaining 2 strains were 0.05 and 0.20 micrograms/ml. MICs against 2 out of 3 strains Acinetobacter lwoffi were 1.56 micrograms/ml, and that of the remaining 1 strain was 0.39 microgram/ml. MICs against 2 strains of Pseudomonas cepacia were 1.56 micrograms/ml. MICs against a strain of Pseudomonas putida and a strain of Citrobacter diversus were 0.78 and less than 0.025 microgram/ml, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

We have carried out laboratory and clinical studies on cefpirome (CPR, HR 810). The results are summarized as follows. CPR was given by 30-minute drip infusion to 3 children at a single dose of 20 mg/kg. After the 30-minute drip infusion, the mean peak serum level of CPR was 65.7 +/- 2.2 micrograms/ml at the end of infusion, and the mean half-life was 1.49 +/- 0.046 hours. The mean urinary excretion rate of CPR was 57.0 +/- 25.8% in the first 8 hours after the 30-minute drip infusion of 20 mg/kg. Treatment with CPR was made in 9 cases of pediatric bacterial infections; 1 case each of tonsillitis, pharyngitis, and bronchopneumonia, 4 cases of pneumonia, 2 cases of urinary tract infection. Results obtained were excellent in 6 cases, good in 3 cases. No significant side effects due to the drug were observed except one case of elevated GOT and GPT, and 3 cases of eosinophilia.

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.

Cefpirome (HR 810, CPR), a new cephem antibiotic, was investigated for its experimental and clinical studies in pediatrics. The results obtained are summarized as follows. 1. Plasma and urinary levels of CPR were determined in 2 children (age 5 and 7 years) after the one shot intravenous injection of the drug at 20 mg/kg. Average plasma levels of the drug were 44.7 micrograms/ml, 28.5 micrograms/ml, 10.5 micrograms/ml, 4.6 micrograms/ml and 1.5 micrograms/ml at 1/2 hour, 1 hour, 2 hours, 4 hours and 6 hours, respectively, and the average half life was 1.57 hours. Average urinary levels of the drug were 1,785 micrograms/ml, 545 micrograms/ml and 198 micrograms/ml at 0-2 hours, 2-4 hours, 4-6 hours, respectively and the average urinary elimination rate was 52.0%. The results were nearly equivalent to those in adults except for urinary elimination rate which tended to be slightly lower than that in adults. 2. Cerebrospinal fluid levels in 3 cases of purulent meningitis treated with CPR were investigated. Cerebrospinal fluid levels in a case of Neisseria meningitidis were 11.5-23.1 micrograms/ml at 1 hour and 0.94 microgram/ml at 5 hours after intravenous injection of 44.4 mg/kg, 4 times a day. Cerebrospinal fluid levels in a case of Streptococcus pneumoniae were 1.01-4.23 micrograms/ml at 1 hour after intravenous injection of 49.0 mg/kg, 6 times a day, and in the other case with Streptococcus pneumoniae, the levels were 16.8-37.1 micrograms/ml at 1 hour, 11.3 and 3.60 micrograms/ml at 3 and 4 hours after intravenous injection 52.2 mg/kg, 6 times a day. These results are not inferior to those with cefotaxime or ceftriaxone. These levels appear to be higher than MIC90 values against Escherichia coli, Streptococcus agalactiae, S. pneumoniae or Haemophilus influenzae which are the major pathogens of these diseases. 3. CPR was given to 62 patients and clinical efficacy, bacteriological response and adverse reactions were evaluated. Evaluated cases for clinical efficacy included 3 cases of purulent meningitis, 1 case of acute purulent otitis media, 2 cases of acute purulent tonsillitis, 1 case of acute bronchitis, 49 cases of acute pneumoniae, 1 case of scarlet fever, 1 case of acute osteomyelitis, 1 case of acute enterocolitis, and 2 cases of acute UTI, totalling 61 cases. Clinical efficacies were excellent in 38 cases, good in 22 cases and fair in 1 case with an efficacy rete of 98.4% (excellent + good).(ABSTRACT TRUNCATED AT 400 WORDS)

We conducted a pharmacokinetic and clinical study on cefpirome (HR 810, CPR), an aminothiazolylmethoxyiminoacetamido cephalosporin (ATOIC), and obtained the following results. 1. Concentrations in blood/excretion in urine. We studied pharmacokinetic in children upon intravenous bolus injections and 30-minute and 1-hour intravenous drip infusions in single dosages of 10, 20, and 40 mg/kg, and obtained virtually the same results as those found in adult subjects. Upon intravenous bolus injections, mean blood concentrations 30 minutes after administration of 10, 20, and 40 mg/kg were 26.1, 47.8, and 82.8 micrograms/ml, respectively, and half-lives were 1.13, 1.43, and 1.26 hours, respectively. Upon 30-minute intravenous drip infusion, mean blood concentrations on completion of the drip infusions of 10, 20, and 40 mg/kg were 43.2, 106.9, and 163.0 micrograms/ml, respectively, and half-lives were 1.15, 1.09, and 1.15 hours, respectively. In addition, upon 1-hour intravenous drip infusion, mean blood concentrations on completion of infusion were 27.1 micrograms/ml for 10 mg/kg and 47.5 micrograms/ml for 20 mg/kg, and half-lives were 1.09 and 1.40 hours, respectively. A clear dose response was observed at all dosages for either administration method. Mean excretion rates in urine in the first 8 hours after administration were 60.6-71.1% upon intravenous bolus injections of 10-40 mg/kg, and upon intravenous drip infusion, the values were 50.2-83.8% for administration of 10-40 mg/kg 6 or 7 hours after completion of drip infusion. 2. Concentrations in the cerebrospinal fluid Penetration into the cerebrospinal fluid was studied in 2 subjects, and a concentration of 0.28-5.19 micrograms/ml was observed upon administration of 50 mg/kg, a moderate degree of penetration compared to the penetration of cephalosporins of group 5 studied up to now. 3. Clinical results Evaluation of clinical effects of CPR on various types of bacterial infections was conducted in 56 subjects, excluding 3 subjects who had diseases which were excluded from the study. The breakdown was as follows: 3 cases of meningitis, 1 case of septicemia, 25 cases of bronchial pneumonia, 1 case each of tonsillitis and infection of the external acoustic meatus, 2 cases each of scarlet fever and phlegmon, 8 cases each of lymphadenitis and urinary tract infections, and 5 cases of staphylococcal scalded skin syndrome. Results of excellent or good were obtained in 54 subjects for an efficacy rate of 96.4%.(ABSTRACT TRUNCATED AT 400 WORDS)

Pharmacokinetics and clinical effects of cefpirome (CPR, HR 810) in children were studied. When 20 mg/kg and 40 mg/kg doses of CPR were administered to 4 children through 30 minutes' drip infusion, half-lives were 1.23 +/- 0.23 (mean +/- S.D.) hours and 1.37 +/- 0.35 (mean +/- S.D.) hours, respectively for the 2 dose levels, and recovery rates in urine in the first 6 hours after administration were 74.8% and 56.1%, respectively. CPR was administered to 15 cases (3 tonsillitis, 3 bronchitis, 5 bronchopneumonia, 1 acute cystitis, 1 coxoiliatitis, 1 otitis media, 1 otitis externa). The efficacy rate was 86.7%. Seven strains of bacteria were isolated and identified 4 Haemophilus influenzae, 3 Staphylococcus aureus, 1 Pseudomonas sp. from these cases. These bacteria in children were followed after administration of CPR. Six strains were eradicated and one was reduced in number. No adverse effects of CPR were observed except in 2 cases, one of which showed transient eosinophilia and the other showed a transient increase of transaminase. These results suggest that CPR may be an effective and safe drug to use on children clinically.
