We have carried out laboratory and clinical studies on cefpodoxime proxetil (CS-807, CPDX-PR). The results are summarized as follows. CPDX-PR was given via oral administration to each 2 children at a single dose of 3 mg/kg and to each of 3 children in a 100 mg tablet. After the oral administration, mean peak serum levels of CPDX obtained for the 2 dose levels were 1.86 +/- 0.35 micrograms/ml and 2.16 +/- 0.63 micrograms/ml at 2 hours, respectively, and mean half-lives were 1.31 +/- 0.02 hours and 1.47 +/- 0.18 hours, respectively. The mean urinary excretion rate of CPDX was 32.8 +/- 1.0% in the first 12 hours after the oral administration of 3 mg/kg. When a dose of 100 mg tablet was given to each of the 3 children, urinary excretion rates in the first 12 hours were 43.5%, 48.6% and 24.8%, respectively. Treatment with CPDX-PR was done in 38 cases of pediatric bacterial infections; 19 cases of tonsillitis, 3 cases of pharyngitis, 1 case of bronchitis, 3 cases of pneumonia, 3 cases of scarlet fever, 2 cases of impetigo, 4 cases of UTI and 1 case each of phlegmone, subcutaneous abscess and balanitis. Results obtained were excellent in 23 cases, good in 15 cases. No significant side effect due to the drug was observed in any cases.

Pharmacokinetic and clinical studies of imipenem/cilastatin sodium (MK-0787/MK-0791), a newly developed combined antibiotic in a 1:1 ratio, were performed in the field of pediatrics. The MK-0787/MK-0791 was administered to 15 children. Ten and 20 mg/kg doses of MK-0787 were administered by a intravenous drip infusion for 30 minutes to 3 children each. In the remaining 9 cases, MK-0787 doses of 10, 20 and 30 mg/kg were administered to 3 children each by a 1 hour intravenous drip infusion. Levels of MK-0787 and MK-0791 in plasma, urine and urinary recovery rate of the drugs were also determined. In addition, MK-0787/MK-0791 was administered to a total of 29 children; 2 children with bronchitis, 16 with pneumonia, 4 with UTI, 2 with purulent lymphadenitis and 1 child each with tonsillitis, septicemia suspected disease, peritonitis, staphylococcal scalded skin syndrome and osteomyelitis/bacteremia. The average single dose was 15.3 mg/kg of MK-0787 and administrations were performed by 20-60 minutes intravenous drip infusion 3-4 times daily for an average period of 6 days. The clinical and bacteriological effects of this drug were evaluated in these cases and adverse reactions and unusual laboratory findings were also studied in a total of 33 cases including 4 other drop-out cases. Results of these studies were summarized as follows. In 6 children, 3 each who were given doses of 10 or 20 mg/kg, the mean peak plasma concentrations of the drugs were found at the end of the 30 minutes-infusion with values of 35.20 and 74.90 micrograms/ml for MK-0787 and 44.85 and 93.32 micrograms/ml for MK-0791 after the dose of 10 and 20 mg/kg, respectively. The peak plasma levels of MK-0791 were approximately 1.3 times higher than those of MK-0787 and higher peak levels were observed in the groups with larger doses of either drugs. In the 10 mg/kg group, the mean half-lives of MK-0787 and MK-0791 were 0.97 and 0.71 hour, respectively and those values were 0.89 and 0.63 hour, respectively in the 20 mg/kg group. In both group, MK-0787 tended to have longer half-lives than MK-0791. In 9 children, 3 each who were administered doses of 10, 20 and 30 mg/kg by a 1 hour intravenous drip infusion had the highest plasma levels for both MK-0787 and MK-0791 at the end of the infusion.(ABSTRACT TRUNCATED AT 400 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.

Fundamental and clinical studies were carried out on cefixime (CFIX) 5% granules, and the results are summarized below. Antimicrobial activity Antimicrobial activities of CFIX, cefaclor, cefroxadine, cephalexin and amoxicillin (AMPC) were studied against clinical isolates. CFIX showed greater activities than all the other antibiotics against E. coli, K. pneumoniae, H. influenzae, P. mirabilis, E. cloacae and S. marcescens, but it was slightly less active than AMPC against S. pyogenes. Absorption and excretion Serum concentrations and urinary excretions of CFIX were determined following single or repeated oral administration. In 8 patients given single dose of CFIX 1.5 or 3.0 mg/kg, mean serum concentrations were 1.27 and 1.09 micrograms/ml at 2 hours, 1.27 and 1.35 micrograms/ml at 4 hours, 0.85 and 1.10 micrograms/ml at 6 hours, 0.17 and 0.24 micrograms/ml 12 hours after administration, respectively. Mean serum half-lives were 2.54 hours for the dose of 1.5 mg/kg and 2.60 hours for 3.0 mg/kg. Urinary recovery rates in the 12-hours urine varied 6.7 to 33.6%, with an average of 13.5%. In 3 patients given a repeated dose of CFIX 3.0 or 5.6 mg/kg b.i.d., the serum concentrations were 0.23-1.01 micrograms/ml at 0 hour, 1.91-2.80 micrograms/ml at 2-4 hours and 1.13-2.07 micrograms/ml at 6-8 hours after administration. Clinical study The CFIX was given orally by mainly b.i.d. at a daily dose of 4.4-11.6 mg/kg for 4-15 days to a total of 33 patients consisting of 3 patients with pneumonia, 3 with bronchitis, 9 with tonsillitis, 15 with UTI, one each with scarlet fever, lymphadenitis and colitis. Clinical responses were excellent in 24 patients, good in 8 and fair in 1, with an effectiveness rate of 97.0%. All of the 21 bacterial isolates examined were eradicated after CFIX treatments including 3 beta-lactamase producing strains. No side effects of abnormal laboratory findings were observed in these patients.

A fundamental and clinical study of ceftizoxime (CZX) suppositories was performed in pre-school and school-age children. The average time courses of CZX serum and urinary concentrations after administration of CZX suppository 250 mg (i.e. per kg body weight doses of 8.3-10.9 mg) to 4 school-age children were as follows. Serum concentrations: 6.1 micrograms/ml at 15 minutes, 6.3 micrograms/ml at 30 minutes, 3.8 micrograms/ml at 1 hour, 1.7 microgram/ml at 2 hours, 0.5 microgram/ml at 4 hours and 0.2 microgram/ml at 6 hours with a biological half-life of 1.43 hours. Urinary concentrations: 885 micrograms/ml for 0-2 hours, 209 micrograms/ml for 2-4 hours and 112 micrograms/ml for 4-6 hours with an average 6-hour urinary recovery rate of 25.6%. The clinical and biological effectiveness and adverse reactions were studied in 11 infants and school-age children afflicted with various infections (acute purulent tonsillitis, 1; acute bronchitis, 3; acute pneumonia, 4; and UTI, 3). The clinical responsiveness was "excellent" in 8, "good" in 2, and "failure" was recorded in 1, with an overall efficacy of 90.9% inclusive of "excellent" and "good". The microbiological effectiveness of CZX suppositories on presumed pathogenic organisms comprising 4 strains of H. influenzae, 1 strain of H. parainfluenzae, and 3 strains of E. coli was satisfactory, as evidenced by the substantially high eradication rate of 87.5%. The only organism that survived CZX suppository treatment was 1 strain of H. influenzae which however was greatly decreased. The only side effect was diarrhea in 1 patient, which however did not necessitate withdrawal of the drug. The only laboratory test abnormality was GOT and GPT elevation in 1 patient which was normalized within 8 days. In conclusion, CZX suppositories were found to be efficacious and safe for treatment of bacterial infections in children.

A clinical trial of ceftizoxime suppositories (CZX-S) was performed to evaluate the therapeutic effectiveness in children with bacterial infection. The subjects were 10 children comprising 4 with pneumonia, 3 with lacunar tonsillitis, 2 with pharyngitis, and 1 with UTI. They were given 1 suppository containing either 125 mg or 250 mg of CZX 2 to 4 times a day. The daily per kg body weight dose ranged from 17.1 to 60.0 mg. The result was "markedly effective" in 3, "effective" in 6, and "failure" was recorded in 1. Bacteriologically, successful eradication of causative organisms was confirmed in all the 4 children who underwent the test. No clinical side effects were observed. The only laboratory test abnormality recorded in a single patient was eosinophilia, which was not definitely ascribable to CZX-S. In conclusion, CZX-S have proved to be a clinically safe and effective antibiotic preparation in infantile infection, even in children whose treatment with conventional antibiotics is associated with difficulties.

A clinical trial of ceftizoxime suppositories (CZX-S) was conducted in children whose chemotherapy was considered to be best performed in this dosage form at the physician's discretion. The subjects were 5 children with infection, consisting of 2 with pneumonia, 1 with tonsillitis, and 2 with UTI. The results were as follows. The clinical response to CZX-S was "markedly effective" in 3 and "effective" in 2, with the 100% effectiveness rate. Neither adverse drug reactions nor abnormal laboratory tests were detected. No unwanted expulsion of the suppository occurred. The serum concentration of CZX 30 minutes after the first insertion ranged from 8.38 to 11.4 micrograms/ml, and the urinary concentration of CZX in the 6-hour urine collections, from 23.6 to 290 micrograms/ml.

Ceftizoxime suppository (CZX-S) was given to 6 patients, with the following results. The peak serum concentration of CZX was 1.8-7.5 micrograms/ml at 30 minutes after dosing of CZX-S with 9.6-16.7 mg/kg. The antibacterial activity of CZX revealed that the drug can be expected to be effective sufficiently. The overall effect of CZX-S was "markedly improved" in 1 and "moderately improved" in 3 of the 4 patients with pneumonia and "markedly improved" in 1 and "slightly improved" in 1 of the 2 with UTI. CZX-S caused a slight increase in frequency of defecation in 2 of the 6 patients. There were no abnormal findings of symptoms or laboratory test values which were ascribable to side effects.

This report summarizes the results of joint studies in pediatrics on aztreonam, the first monobactam antibiotic for practical use. Pharmacokinetics was studied in 53 cases administered with 10, 20, 40 and 50 mg/kg of aztreonam (AZT) by intravenous injection and 20 cases with 10, 20, 30, and 40 mg/kg by drip infusion. All the cases had normal hepatic and renal functions at the administration. T1/2 was in a relatively fixed range of 1.35-1.56 hours in intravenous injection cases and 1.30-1.55 hours in drip infusion. One hour after commencing administration of standard 20 mg/kg, the serum concentrations were 50.18 +/- 4.24 micrograms/ml in intravenous injection and 116.33 +/- 10.18 micrograms/ml in drip infusion and even 6 hours after the end of the administration, they were 5.80 +/- 1.16 micrograms/ml and 3.38 +/- 0.58 micrograms/ml, respectively. The cerebrospinal fluid penetration was studied on suppurative meningitis (5 cases) and nonbacterial meningitis (3 cases). The penetration was generally good with sufficient concentration for meningitis caused by E. coli and H. influenzae. Amount of the penetration decreased as the cases were improved. Twenty-nine (29) cases were excluded and 262 cases of total 291 were clinically assessed, and the pathogen-isolated 167 cases of 262 were principally analyzed. Efficacy of AZT was "excellent" for all 3 cases of E. coli sepsis and 1 case of N. meningitidis meningitis and "good" for 1 case of H. influenzae meningitis. The effective rate was 94.6% for 37 pneumonia cases, 94.7% for 76 UTI cases and 88.5% on the whole including as many as 98 "excellent" cases. However, the effective rate for 21 enteritis cases was only 52.4%. Similar trend was observed in the pathogen-unknown group and overall effective rate of total 267 cases was 86.8%. The clinical effect by pathogen was 97.7% for 44 E. coli cases and 97.1% for 34 H. influenzae cases, showing excellent results for the GNB group. AZT was also effective for 8 out of 11 P. aeruginosa cases. With regard to microbiological effect by pathogen, AZT showed a high rate of bacterial elimination for GNB, primarily 98.1% for E. coli and 100% for H. influenzae followed by 76.9% for P. aeruginosa. However, it was only 30.0% for Salmonella. Excluding the Salmonella cases, GNB elimination rate was 93.5%. Clinical and microbiological dose response was not clear partly because, same as the previous studies, the effective rate of AZT was high. It was considered, however, standard dose of 20 mg/kg X 3 approximately 4 times a day was recommendable.(ABSTRACT TRUNCATED AT 400 WORDS)

Serum and urinary concentrations and recovery rates of aztreonam (SQ26,776, AZT), a newly developed antibiotic, were studied for a total of 20 pediatric cases by one-shot intravenous injections of 10, 20 and 40 mg/kg to 3, 4 and 3 cases, respectively, and by intravenous drip infusion of 10, 20 and 40 mg/kg to 3, 4 and 3 cases for 1 hour, respectively. Clinical and bacterial effects of AZT were studied by administering 76.7 mg/kg per day on average for a total of 36 cases of tonsillitis (6), pneumonia (13), otitis media and pneumonia complication (1), pleurisy (1), sinusitis (1) and UTI (14). The above daily dose was given t.i.d. (9 cases) or q.i.d. (27 cases), by intravenous drip infusion for 30 minutes for one t.i.d. case and by one-shot intravenous injection for 7 days for the remaining 35 cases. Also, side effect and laboratory values were examined for 43 cases including 7 dropouts. Serum concentration of AZT in 10 pediatric cases were measured by dosing 10, 20 and 40 mg/kg by one-shot intravenous injection to 3, 4 and 3 cases, respectively. In every dosage group, the serum concentrations were highest 5 minutes after the intravenous injection with average values of 91.0, 174.0 and 175.3 mcg/ml, respectively. Dose response was observed between 10 mg/kg dose group and 20, 40 mg/kg dose groups, but it was not between 20 mg/kg group and 40 mg/kg group. This was considered to be attributable to the individual case-fluctuations in the 2 groups and to a high concentration case of 240.0 mcg/ml in the 20 mg/kg group. Half-life of each dosage group was 1.55, 1.65 and 1.93 hours. Serum concentrations of AZT in 10 pediatric cases at the dosage level of 10, 20 and 40 mg/kg for 3, 4 and 3 cases, respectively, by 1 hour intravenous drip infusion were highest at the end of the administration with average values of 95.7, 126.0 and 170.7 mcg/ml, respectively. There was a dose response among the 3 groups and the half-life of them were 1.02, 1.41 and 2.48 hours, respectively. A longer half-life of the 3rd group with 40 mg/kg administration than the other 2 groups was due to 1 particular case of 4.44 hours with unknown cause of such an exceptional extension.(ABSTRACT TRUNCATED AT 400 WORDS)
