Bacteriological, pharmacokinetic and clinical studies on cefpodoxime proxetil (CPDX-PR, CS-807), a new oral cephem antibiotic, were carried out in the field of pediatrics. The results obtained are summarized as follows. 1. Antibacterial activities of R-3746 (Na-salt of cefpodoxime (CPDX] against clinically isolated strains of Streptococcus pneumoniae, Streptococcus pyogenes, Staphylococcus aureus, Enterococcus faecalis, Branhamella catarrhalis, Escherichia coli, Proteus mirabilis and Haemophilus influenzae were compared with those of cefaclor, cephalexin and cefadroxil. R-3746 is superior to other antibiotics against S. pneumoniae, S. pyogenes, B. catarrhalis and Gram-negative rods. 2. Serum concentrations of CPDX after administration of CPDX-PR at doses of 3 mg/kg (fasting), 6 mg/kg (non-fasting) and 6 mg/kg (fasting) were determined. Mean AUC (area under curve)'s of CPDX obtained were 9.60, 31.35 and 17.89 micrograms.hr/ml, respectively for the 3 dosages. The mean half-lives of CPDX were 3.35, 1.88 and 1.76 hours, respectively. The mean urinary recovery rate within 8 hours after administration of CPDX-PR at a dose of 3 mg/kg (fasting) was 39.2%. 3. CPDX-PR was administered to 37 pediatric patients with various bacterial infections (pyelonephritis 9, cystitis 4, pneumonia 7, acute bronchitis 3, otitis media 2, tonsillitis 10, subcutaneous abscess 1 and purulent lymphadenitis 1). The overall clinical efficacy rate was 91.9% and the overall bacteriological eradication rate was also 91.9%. 4. No adverse reactions were observed. Abnormal laboratory findings were moderate, eosinophilia in 2 and slight elevation of GOT and GPT in 1. The taste and the odor of the CPDX-PR preparation was sufficiently tolerable. From the above results we have concluded that CPDX-PR is a useful oral antibiotic in the treatment of bacterial infections in children.

Twenty nine children were treated with cefpodoxime proxetil (CPDX-PR, CS-807) and the clinical efficacy and side effects were evaluated. Ages of the patients ranged from 2 months to 10 years. Dose levels of CPDX-PR ranged from 7.5 to 12.0 mg/kg/day for 5 to 12.7 days. The 29 patients included 9 tonsillitis, 2 otitis media, 5 scarlet fever, 3 bronchopneumonia, 1 lymphadenitis, 8 urinary tract infections and 1 staphylococcal scalded skin syndrome, and they were evaluated for the clinical efficacy of CPDX-PR. Results were excellent in 21 and good in 8 patients. Out of the 29 patients, 3 cases showed diarrhea and 2 cases showed elevated GOT and GPT. The pharmacokinetics of CPDX-PR was studied in 9 patients whose ages ranged from 1 to 9 years. The serum peak concentrations of CPDX in 5 patients were between 1.37 and 4.10 micrograms/ml (mean: 2.53 micrograms/ml) at 1 to 6 hours after dosing 3 mg/kg before meals. Those of 4 patients ranged 3.29 to 4.88 micrograms/ml (mean: 4.36 micrograms/ml) at 2 hours after administering 6 mg/kg before meals. Portions of CPDX excreted into urine within 6 hours ranged from 20.3 to 34.3% (mean 27.1%) in 5 patients who were given 3 mg/kg, and ranged from 24.1 to 65.7% (mean 41.1%) in 4 patients given 6 mg/kg.

Children with acute infections were treated with cefpodoxime proxetil (CPDX-PR, CS-807), a new oral cephalosporin. 1. A girl of 4 years old, weighing 17 kg, and another girl of 12 years old, weighing 33 kg, were administered orally each 3 mg/kg of CPDX-PR. Blood levels of CPDX reached peaks of 1.39 and 2.26 micrograms/ml at 4 hours-post-dose, and T1/2's were 2.09 and 2.63 hours, respectively. Cumulative urinary recovery rates for 8 hours were 57.3 and 80.9%, respectively. 2. A total of 30 patients was treated with CPDX-PR. These patients included 10 with acute tonsillitis, 6 with acute bronchitis, 5 with bronchopneumonia, 2 with scarlet fever and 2 with urinary tract infections, and one each with acute pneumonia, acute otitis media, acute otitis media plus sweat gland abscess, staphylococcal scalded skin syndrome and acute lymphadenitis. The treatment was effective in 27 cases out of 29 (except one with an unknown response) with a clinical efficacy rate of 93.1%. 3. Bacteriological responses to CPDX-PR were as follows; eradication of pathogen in 7, and unknown in 2 out of 9 cases from whom pathogens had been isolated prior to the treatment. 4. As a side effect, diarrhea was observed in 1 patient, but it was possible to continue the treatment. With regard to laboratory tests, a slight elevation of GOT and slight elevations of GOT and GPT were found in 1 case each.

Cefpodoxime proxetil (CS-807, CPDX-PR), a new cephalosporin antibiotic, was investigated for its usefulness in pediatrics. 1. The total number of patients treated were 21 with their ages ranging from 3 months to 9 years and 1 month, consisting of 5 male and 16 female infants. 2. Single dosages of the drug ranged between 4.4 mg and 5.8 mg/kg with oral administration for 3 times daily in fasting. A total aggregated dosage was between 46.4 mg/kg and 200.0 mg/kg. The length of administration was 3 to 12 days. 3. The breakdown of symptoms were 9 cases of acute pharyngitis, 5 cases of acute tonsillitis, 3 cases of acute bronchitis, and 1 case each of impetigo + purulent rhinitis, cervical lymphadenitis, scarlet fever, and urinary tract infection. 4. The clinical efficacy rate was 100% with 18 excellent responses and 3 good responses. 5. The bacteriological efficacy rate was 90.9% in eradication rate, based on results on 17 strains of suspected causative microorganism among which 10 strains were eradicated, 1 strain was decreased, and 6 strains were unknown. 6. There was no side effect during the treatment and after the discontinuation, while, in clinical laboratory tests, GOT and GPT were elevated in 1 case which was judged as abnormal. No patient refused the drug. CPDX-PR was considered to be very useful drug because of its excellent efficacy and safety in pediatrics in treating infectious diseases.

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.
