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)

Fundamental and clinical studies on cefuzonam (L-105, CZON), a newly semisynthesized cephem antibiotic, were carried out in the field of pediatrics and the following results were obtained. Antibacterial activities of CZON against clinically isolated strains of Staphylococcus aureus, S. epidermidis, Streptococcus pneumoniae, S. pyogenes, Escherichia coli, Klebsiella pneumoniae, Haemophilus parainfluenzae and H. influenzae were compared with those of cefmenoxime (CMX), latamoxef (LMOX), cefoperazone (CPZ), cefmetazole (CMZ), cefotiam (CTM) and cefazolin (CEZ). CZON was nearly as active as CEZ against S. aureus and S. epidermidis and superior to other antibiotics against other Gram-positive cocci. Against Gram-negative rods, CZON was as active as CMX and superior to other 5 antibiotics compared. Serum concentrations and urinary excretion rates after intravenous bolus injection of CZON at doses of 10 mg/kg, 20 mg/kg and 40 mg/kg for 5 minutes in 1, 5 and 4 cases, respectively, were determined. Mean serum concentrations of CZON at these dose levels were 11.0, 43.8 and 111.5 micrograms/ml at 15 minutes, 2.4, 10.3 and 30.3 micrograms/ml at 1 hour and 0.17, 0.72 and 1.28 micrograms/ml at 4 hours, with serum half-lives of 1.79, 0.88 and 1.19 hours, respectively. Mean cumulative urinary excretion rates within 6 hours after administration were 47.9, 56.3 and 40.3%, respectively. Thirty-four pediatric patients with various bacterial infections (tonsillitis 2, acute bronchitis 1, pneumonia 14, pyothorax 1, sepsis 1, suppurative lymphadenitis 1, UTI 13 and enteritis 1) were treated with CZON at a daily dose of 40-94 mg/kg t.i.d. or q.i.d.. The overall clinical efficacy rate was 94.1%. No adverse reactions were observed except 2 cases with mild diarrhea. Abnormal laboratory findings were also mild; slight elevation of GOT and GPT in 2, eosinophilia in 1 and thrombocytosis in 1. These results clearly indicate the usefulness of CZON in the treatment of bacterial infections in children.

Cefuzonam (L-105, CZON), a new injectable cephalosporin, was used in 12 pediatric patients with infections. The following is a summary of the results: The 12 cases included 3 cases of tonsillitis (pathogen: Haemophilus parainfluenzae in 1 case, Haemophilus influenzae in 2 cases), 4 cases of pneumonia (Staphylococcus aureus in 1 case, pathogen unknown in 3 cases), 2 cases of nephropyelitis (Escherichia coli in 2 cases), 1 case of purulent lymphadenitis (pathogen unknown), 1 case of purulent thyroiditis (mixed infection of Streptococcus milleri, Haemophilus aphrophilus and anaerobes), and 1 case of vulvar abscess (E. coli). Dose levels of CZON were 42.9 approximately 93.3 mg/kg/day divided into 3 or 4 times and the drug was intravenously injected for 6 to 12 days. Clinical efficacies were excellent in 4 cases, good in 5 cases, and poor in 3 cases, with the efficacy rate of 75.0%. The 3 cases with poor efficacy consisted of 1 case each of pneumonia complicated with chronic granulomatosis, purulent thyroiditis associated with piriform recess fistula, and purulent lymphadenitis of armpit developed after surgical operation of congenital heart disease. In the first 2 cases satisfactory efficacy was not obtained by chemotherapy alone, and complete cure was seen after surgical operation. Side effects were not observed clinically. One case each of slight prolongation of prothrombin time and transient elevations of GOT and GPT values were noted but no severe abnormalities were found in laboratory tests.(ABSTRACT TRUNCATED AT 250 WORDS)

Cefuzonam (L-105, CZON) was studied in pediatric infections. A summary of the results it as follows: For recently isolated Staphylococcus aureus strains, Peak MICs of CZON were distributed between 0.39 and 0.78 micrograms/ml showing a greater susceptibility of S. aureus to CZON than to cefoperazone (CPZ), latamoxef (LMOX), and cefmenoxime (CMX). Peak MICs of CZON for Escherichia coli were 0.10-0.20 micrograms/ml, similar to those of CPZ, LMOX, and CMX. Ampicillin (ABPC)-resistant strains were also susceptible to CZON. MICs for Salmonella were similar to those for E. coli. Peak MICs of CZON for Vibrio parahaemolyticus were 0.20-0.39 micrograms/ml. The susceptibility of the bacteria to CZON was far greater than to ABPC, and was similar to CPZ, LMOX, and CMX. With 20 mg/kg drip infusion, serum concentrations reached their peaks at the end of administration with values of 20.6-68.7 micrograms/ml, which decreased to 0.43-1.70 micrograms/ml after 2 hours. Half-lives of CZON in serum were 0.68-1.2 hours. With 50 mg/kg drip infusion, serum concentrations reached their peaks at the end of administration with levels of 69.0-82.0 micrograms/ml, and at after 2 hours 1.85-3.45 micrograms/ml. Thus, an apparent dose response was observed. Half-lives of CZON in serum were 0.63-0.99 hours. Urinary recovery rates in 6 hours were 39.9-80.5%. A total of 44 cases of 10 different types of acute pediatric infections was treated by CZON intravenous drip infusion as the main therapeutic procedure. The efficacy rate was 93.2%, and the compound was effective on purulent infections, acute urinary tract infection, etc. with pathogens such as ABPC-resistant S. aureus, E. coli, and Enterococcus faecalis. Dosage levels per day were 50 to 80 mg/kg in most cases. In infections with S. aureus (8 strains), Streptococcus pneumoniae (3 strains), E. faecalis (1 strain), Haemophilus parahaemolyticus (1 strain), Haemophilus parainfluenzae (2 strains), Haemophilus influenzae (11 strains), Bordetella pertussis (1 strain), E. coli (3 strains), a total of 30 strains, bacterial elimination was noted with an exception of 1 strain of S. aureus. The compound was used for 4 to 15 days, but side effects observed clinically were only 1 case of diarrhea and 1 case of thrombocytosis.

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)

Studies were carried out on the penetration of cefuzonam (L-105, CZON), a new synthetic cephalosporin antibiotic, into cerebrospinal fluid, and on the clinical efficacy against bacterial infections. The results are summarized as follows: Concentrations of CZON in cerebrospinal fluid at 1 hour after intravenous administration of 100 mg/kg in cases of furunculosis of the external canal, encephalitis and mumps meningitis were 0.56 micrograms/ml, 1.44 micrograms/ml and 0.33 micrograms/ml, respectively. Concentrations of CZON in cerebrospinal fluid at 1 hour after intravenous administration of 100 mg/kg in 3 cases of purulent meningitis were 2.80-6.40 micrograms/ml at the acute stage and 0.56-1.45 micrograms/ml even at the recovering stage. Sensitivities of clinically isolated strains to CZON were determined and expressed as MIC. MICs of CZON on Haemophilus influenzae, Escherichia coli, Proteus mirabilis and Klebsiella pneumoniae were similar to MIC's of cefmenoxime (CMX), and lower than those of cefoperazone (CPZ), cefmetazole (CMZ), cefatiam (CTM) and Cefazolin (CEZ). The MIC of CZON on Staphylococcus aureus was similar to those of CEZ, CMZ and CTM, and lower than those of CMX and CPZ. Clinical responses of CZON were good in 2 cases of purulent meningitis, good in 2 cases of pyothorax, excellent in 1 case of septicemia, excellent in 3 cases of urinary tract infections, excellent in 7 cases and good in 3 cases out of 10 cases of pneumonia. Clinical responses of other diseases were excellent in 4 cases of bronchitis, good in 1 case of furunculosis of the external canal, excellent in 1 case of tonsillitis. No side effects nor abnormal laboratory findings were observed except 2 cases of mild diarrhea out of 24 cases.

Cefuzoname (CZON, L-105) a newly developed cephalosporin, has broad spectrum on Gram-positive or -negative bacteria and may also be effective against Staphylococcus aureus against which third generation cephalosporins are largely ineffective. We studied the pharmacokinetics and clinical effects of CZON on infectious disease of children. The diseases we studied included 2 cases of bacterial meningitis and 1 case each of viral meningitis, enterocolitis, upper respiratory infection, pneumonia, and mycoplasmal pneumonia. CZON was administered by drip infusion. Dose levels were 20-53 mg/kg/30-60 minutes, 3 times a day. For 5 cases, was studied time course of concentrations of CZON in plasma. Median T 1/2 was 0.96 hour. Concentrations in cerebrospinal fluid (CSF) were studied in cases of pneumonia and bacterial meningitis. In the case of pneumonia the CSF concentration of CZON was 0.272 microgram/ml after 45 minutes, in the case of meningitis they were 0.155 microgram/ml after 5 hours. Both of these values were higher than MIC of 0.025 microgram/ml against Haemophilus influenzae which was isolated from a case of bacterial meningitis. This MIC was lower than that of cefotiam and cefazolin, as well as of cefmenoxime. Clinical effects were excellent on pneumonia, good on upper respiratory infection, fair on mycoplasmal pneumonia. CZON, however, was ineffective in the treatment of a case of bacterial meningitis from which a susceptible strain of H. influenzae was isolated.(ABSTRACT TRUNCATED AT 250 WORDS)
