Bacteriological, pharmacokinetic and clinical studies on cefpirome (CPR, HR 810), a new cephem antibiotic, were carried out in the field of pediatrics. The results obtained are summarized below. 1. Antibacterial activities of CPR against clinically isolated strains of Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes, Streptococcus agalactiae, Escherichia coli, Klebsiella pneumoniae, Haemophilus influenzae and Haemophilus parainfluenzae were superior to those of ceftazidime. 2. Plasma concentrations and urinary excretion rates after intravenous bolus injection of CPR at doses of 10, 20 and 40 mg/kg for 5 minutes in 2 cases each were determined. Mean peak plasma concentrations of CPR at these dose levels were 33.9, 62.9 and 96.0 micrograms/ml at 15 minutes with plasma half-lives of 1.58, 1.69, and 2.13 hours, respectively. Mean cumulative urinary excretion rates in the first 8 hours after administration were 51.2, 78.0 and 74.9%, respectively. 3. Ten patients with bacterial infections (pneumonia 5 cases, urinary tract infection 5 cases) were treated with CPR at a daily dose of 16-79 mg/kg/day. The overall clinical efficacy and bacteriological eradication rates were both 100%. 4. No adverse reactions were observed except in 1 case of mild pain in blood vessels. Abnormal laboratory test results were also mild, slight elevation of GOT, GPT and thrombocytosis in 1 case and eosinophilia in 1 case.

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.

Cefpirome (CPR, HR 810), a new cephem antibiotic, was investigated for its penetration into cerebrospinal fluid (CSF), and its clinical efficacy against bacterial infections. 1. CSF concentrations of CPR following intravenous injection was investigated in 2 patients with purulent meningitis. In one of them, the concentrations were 2.11 micrograms/ml and 1.31 micrograms/ml on 3 and 8 days, respectively, after start of administration. In the other patient, they were 24.2 micrograms/ml, and 1.35 micrograms/ml on 2 days and 7 days after administration, respectively. 2. Antibacterial activities of CPR against clinical isolates, Escherichia coli, Haemophilus influenzae, Staphylococcus aureus and Streptococcus pneumoniae, except those against Pseudomonas aeruginosa, were clearly superior to those of ceftazidime. 3. Clinical efficacies evaluated in 15 patients were "excellent" in 9, "good" in 5 and "unknown" in 1. The overall efficacy rate was 93.0%. 4. Clinical efficacies were "excellent" in 1 patient with bacteremia, "excellent" in 6 and "good" in one of 7 patients with pneumonia, and "good" in both of the 2 patients with purulent meningitis. Clinical efficacies against other diseases were "excellent" or "good", in 1 patient with pyothorax, 1 patient with purulent lymphadenitis, and 2 patients with facial cellulitis. In 1 patient with biliary tract infection, the results of treatment with CPR were "unknown" due to insufficient clinical data. 5. No adverse reactions were observed except in 1 patient who showed an increase in platelet count.

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.

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)

Efficacy and safety of a new injectable cephem antibiotic, cefpirome sulfate (hereafter, CPR), against respiratory tract infections were examined and compared with those of a control drug, ceftazidime (hereafter, CAZ). As a rule, CPR 0.5 g twice a day, 1.0 g twice a day, or CAZ 1.0 g twice a day (hereafter CPR 0.5 g group, CPR 1.0 g group, and CAZ group) was administered for 14 days and the following results were obtained. 1. The total number of cases was 470 (155 cases in the CPR 0.5 g group, 160 cases in the CPR 1.0 g group, and 155 cases in the CAZ group). Among them 390 cases were subjected to analyses of clinical efficacy by the efficacy evaluation committee (131 cases in the CPR 0.5 g group, 131 cases in the CPR 1.0 g group and 128 cases in the CAZ group). 2. Efficacy rates determined by the efficacy evaluation committee were 82.4% (108/131) for the CPR 0.5 g group, 81.7% (107/131) for the CPR 1.0 g group, and 83.6% (107/128) for the CAZ group. Efficacy rates determined by the physician in charge were 82.0% (105/128) for the CPR 0.5 g group, 80.5% (99/123) for the CPR 1.0 g group, and 88.5% (108/122) for the CAZ group. No statistically significant difference was observed among the 3 groups. In evaluation of equivalency, clinical efficacy for the CPR 0.5 g group and the CPR 1.0 g group determined by the clinical efficacy evaluation committee was proved to be statistically equivalent to that for the CAZ group. 3. In patients with pneumonia, efficacy rates determined by the efficacy evaluation committee were 87.1% (61/70) for the CPR 0.5 g group, 80.7% (71/88) for the CPR 1.0 g group, and 78.9% (56/71) for the CAZ group. Efficacy rates determined by the physician in charge were 85.3% (58/68) for the CPR 0.5 g group, 80.7% (67/83) for the CPR 1.0 g group, and 86.2% (56/65) for the CAZ group and no statistically significant difference was observed among the 3 groups. In patients with chronic respiratory tract infection, efficacy rates determined by the efficacy evaluation committee were 77.0% (47/61) for the CPR 0.5 g group, 83.7% (36/43) for the CPR 1.0 g group, and 89.5% (51/57) for the CAZ group. Efficacy rates determined by the physician in charge were 78.3% (47/60) for the CPR 0.5 g group, 80.0% (32/40) for the CPR 1.0 g group, and 91.2% (52/57) for the CAZ group. No statistically significant difference was observed among the 3 groups.(ABSTRACT TRUNCATED AT 400 WORDS)

We conducted a prospective study of CPR in our hospital in order to learn more of the factors influencing outcome. In a 7-month period, 71 patients underwent CPR. Twenty-nine (41%) were successfully resuscitated; of these, 13 (18% of the total group) survived to be discharged from the hospital. Factors associated with a successful outcome included occurrence of cardiopulmonary arrest within 24 h of hospitalization, short duration of CPR, and the absence of cardiogenic shock, sepsis, acute renal failure, cancer, and pneumonia. Factors which did not influence outcome included the patients' age, sex, location in hospital during the arrest (general ward vs. intensive cardiac care unit), time of day of the arrest, or the participation of senior physicians or anesthesiologists in the resuscitation.
