Cefuzonam (L-105, CZON), a new parenteral cephalosporin, was evaluated for its efficacy and safety in 22 children with bacterial infections (Table 1). The results obtained are summarized below. MICs of CZON to 26 strains of isolated organisms are shown in Table 2. MICs to all 14 strains of Haemophilus influenzae and 6 strains of Streptococcus pneumoniae were less than 0.05 microgram/ml. The MIC to 2 strains of Staphylococcus aureus was 0.39 microgram/ml and that to another was 0.78 microgram/ml. Two strains of Escherichia coli showed MICs of less than 0.05 and 0.10 microgram/ml, respectively. The MIC to 1 strain of Enterococcus faecalis was 6.25 micrograms/ml. The CZON was administered in 3 or 4 divided doses at a daily dosage ranging from 58.5 to 85.7 mg/kg by 30-minute drip infusion or intravenous injection to 22 patients (9 cases of pneumonia, 9 cases of tonsillitis, 2 cases of bronchitis, 1 case each of suppurative parotitis and acute pyelonephritis) and the following clinical results were obtained; excellent: 12 cases; good: 7 cases; fair: 3 cases. The overall efficacy rate was 86% (Table 4). Diarrhea was observed in four patients, and was resolved with or without discontinuation of the medication within a week. Anemia was noted in 2 cases. Leucopenia and neutropenia was observed in 1 case. There were a moderate rises in S-GOT and S-GPT activities in 1 patient (Table 4), and they necessitated the cessation of the CZON therapy. The S-GOT and S-GPT activities became normal after the drug treatment was stopped.(ABSTRACT TRUNCATED AT 250 WORDS)

Pharmacokinetic and clinical studies were conducted to evaluate cefuzonam (L-105, CZON), a new cephem type antibiotic, in the pediatric field. A total of 9 pediatric patients (2-14 years) was treated with intravenous injection of CZON: 4 cases with one shot of 20 mg/kg, 2 cases with one shot of 40 mg/kg and 3 cases with drip infusion over 1 hour of 40 mg/kg. CZON concentrations in serum and the excretion in urine were determined. Mean serum concentrations of CZON after one shot intravenous injection of 20 mg/kg were 49.0, 22.7, 9.03, 2.13, 0.37, and 0.09 micrograms/ml at 15, 30 minutes, 1, 2, 4 and 6 hours, respectively. With 40 mg/kg one shot intravenous injections, mean serum concentrations were 117.5, 68.0, 26.2, 8.80, 0.63 and 0.19 micrograms/ml at 15, 30 minutes, 1, 2, 4 and 6 hours, respectively. With 40 mg/kg intravenous drip infusions over 1 hour, mean concentrations were 57.1, 78.8, 12.9, 1.12 and 0.23 micrograms/ml at 30 minutes, 1, 2, 4 and 6 hours, respectively. Mean half-lives were 0.69 hour for 20 mg/kg one shot injections, 0.44 hour for 40 mg/kg one shot injections, and 0.58 hour for 40 mg/kg 1 hour drip infusions. Urinary recovery rates in 6 hour after administration were 70.8% (mean) for the 20 mg/kg one shot injection, 44.1% (1 case) for the 40 mg/kg one shot injection, and 60.0% (mean) for the 40 mg/kg 1 hour drip infusion. CZON was administered in 26 cases of pediatric infections, and the clinical efficacy, antibacterial activity, and side effects were evaluated. Of the 26 cases 2 were excluded for the reason of not having bacterial infection, and the remaining 24 cases were assessed. Included in the 24 cases were 16 cases of acute pneumonia, 2 cases of acute purulent lymphadenitis, and 1 case each of acute bronchitis, acute purulent otitis media, acute apical periodontitis, staphylococcal scalded skin syndrome (SSSS), acute pyelonephritis, and acute enteritis. Clinical efficacy evaluation showed 19 excellent cases and 5 good cases, with an efficacy rate of 100%. Bacteriologically, Staphylococcus aureus 1 strain, Streptococcus pneumoniae 1 strain, beta-Streptococcus 1 strain, Haemophilus influenzae 10 strains, Haemophilus parainfluenzae 1 strain, Proteus mirabilis 1 strain, and Campylobacter jejuni 1 strain were determined or assumed as pathogens, but all of them were eradicated.(ABSTRACT TRUNCATED AT 400 WORDS)

To evaluate the usefulness and the safety of cefuzonam (CZON, L-105) against obstetric and gynecological infections, we conducted clinical trials and obtained the results summarized as follows. 1. Thirteen patients with obstetric and gynecological infections (intrauterine infection 2 cases, adnexitis 7, 1 case each of abscess of adnexa uteri, abscess of the vaginal wall, pyelonephritis, and mammitis) were treated with CZON. The CZON was administered by intravenous injection or intravenous drip infusion, 1 g twice daily for 4 to 7 days (8 g to 14 g in total). The clinical effect was good in 12 and poor in 1. 2. Four cases, on which other antimicrobial agents were ineffective, responded well to CZON. 3. The CZON displayed excellent effects on anaerobic bacteria (Peptostreptococcus anaerobius, Bacteroides fragilis) and Gram negative rods (Escherichia coli, Klebsiella pneumoniae). 4. No side effects or laboratory abnormalities were observed. 5. From the above results, CZON appeared to be an effective and useful drug for obstetric and gynecological infections.
