We have carried out laboratory and clinical studies on norfloxacin (NFLX, AM-715). The results are summarized as follows. NFLX was given through oral administration to one child each at dose levels of 1.7 mg/kg, 2.4 mg/kg and 3.2 mg/kg. After administration, peak serum levels of NFLX obtained for the 3 dose levels were 0.16 micrograms/ml at 1 hour, 0.69 micrograms/ml at 2 hours, 0.81 micrograms/ml at 1 hour, respectively, and half-lives were 2.5 hours, 1.8 hours and 2.7 hours, respectively. NFLX was given through oral administration to 2 children at a dose level of 4.4 mg/kg and to another child at a dose level of 4.8 mg/kg. After administration, mean peak serum levels of NFLX obtained were 1.17 +/- 0.48 micrograms/ml and half-lives were 3.0 +/- 0.5 hours. Urinary excretion rates of NFLX were 14.5% and 28.4% in the first 8 hours after administration of 1.7 mg/kg and 3.2 mg/kg, respectively, and 29.1% in the first 6 hours after administration of 2.4 mg/kg. Mean urinary excretion rates of NFLX were 38.5 +/- 13.0% in the first 8 hours after administration of 4.4 mg/kg and 4.8 mg/kg. Treatment with NFLX was made in 33 cases of pediatric bacterial infections including 5 cases of tonsillitis, 14 cases of enteritis, 10 cases of UTI and 1 case each of bronchitis, balanoposthitis, impetigo and pustulosis. Results obtained were excellent in 14 cases, good in 15 cases. No significant side effect due to the drug was observed in any cases.

Cefixime, the first oral third generation cephalosporin, was administered to 2,832 patients in the USA, UK, FRG and France. 478/1063 patients were treated for urinary tract infections (upper or lower UTI) with 200 mg cefixime bid; clinical cure was obtained in 92 and 96 per cent of upper and lower UTI respectively, and bacteriological cure in 97.5 and 89 per cent of the cases; among 142 patients with a 1 month follow-up, no relapse or reinfection was observed in 78 per cent of cases. Of 521 patients treated for lower respiratory tract infection, 355 received 200 mg cefixime bid and 166 received a single daily dose of 400 mg. Clinical cure was obtained in 88 per cent and 93 per cent patients with pneumonia or bronchitis respectively, with bacteriological cure in 93.2 and 93.8 per cent. Among ENT infections, the most interesting study was in the treatment of sinusitis and otitis. Good clinical results were shown in nearly 95 per cent of cases, with bacteriological cure in more than 90 per cent. The safety studies demonstrated a global 6.6 per cent incidence of undesirable effect. These manifestations were mild and reversible, consisting of abdominal discomfort and minor diarrhea in most cases. The overall effectiveness of cefixime appears to be similar to that of established compounds as far as susceptible pathogens are concerned. However, in clinical trials, cefixime seemed to be effective on isolated bacteria unresponsive to conventional antibiotics.

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 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.

We have evaluated cefixime (CFIX) fine granules for pharmacokinetics and therapeutic effectiveness in children with infections. The results were summarized as follows. Pharmacokinetic parameters after the oral administration of single doses of 1.5 mg and 6.0 mg per kg body weight in a cross-over design in 1 child were as follows: The peak serum CFIX concentrations were 0.65 microgram/ml at 2 to 3 hours and 3.33 micrograms/ml at 4 hours for the low and the high doses, respectively; the respective biological half-lives were 2.4 hours and 2.5 hours, and urinary recovery was 10.3% at 8 hours and 5.2% at 12 hours, respectively. A clinical study was performed on 19 children with infections, including 7 with bronchitis; 3 each with tonsillitis, UTI, and cervical lymphadenitis; and 1 each with pharyngitis, retroauricular lymphadenitis, and enteritis. Doses ranging from 1.8 to 7.8 mg/kg body weight were given b.i.d. or t.i.d. The period of treatment ranged from 3 to 13 days. The therapeutic response was considered "excellent" in 15 and "good" in 4, with an effectiveness rate of 100%. No side effects were observed. The only abnormal laboratory findings was a slight elevation of GOT and GTP recorded in 1 child. It was concluded that CFIX was a promising drug for the treatment of bacterial infections in children.

Laboratory and clinical studies were performed as follows on cefminox (CMNX, MT-141), a new cephamycin antibiotic. Pharmacokinetics Serum concentrations of CMNX were measured in 4 patients given CMNX for prophylactic purpose during cardiac catheterization. In 2 patients given 20 mg/kg of CMNX by intravenous bolus injection, the average of peak serum concentration was 178.9 micrograms/ml at 15 minutes. The mean urinary recoveries in these 2 cases was 66.9% within 6 hours after injection. In 2 patients given 20 mg/kg of this drug by 1 hour drip infusion, the peak serum concentration was obtained at the time drip was completed, and the average value was 68.3 micrograms/ml. Clinical efficacy CMNX was administrated intravenously to 13 patients in dose of 52.9 approximately 96.0 mg/kg t.i.d. or q.i.d. for 4 approximately 7 days; 3 with tonsillitis, 6 with bronchitis, 1 with bronchopneumonia, 1 with UTI, 1 with lymphadenitis and 1 with enterocolitis. The overall efficacy rate was 92.3%, i.e., efficacy was excellent in 12, and poor in 1. Bacteriological efficacy was excellent, i.e., 3 of 3 strains disappeared. Side effects were observed in 3 cases, i.e., 1 case of eruption, 1 case of diarrhea and 1 case of transient eosinophilia. The above results suggest that CMNX is a useful antibiotic for treating pediatric bacterial infections.

Aspoxicillin (ASPC), a new semisynthesized penicillin, was administered to 20 children; by one shot intravenous injection in the doses of 10, 20 and 40 mg/kg to each of 3 children, and by intravenous drip infusion in the doses of 20 and 40 mg/kg over a period of 1 hour to 8 and 3 children, respectively, and the serum levels, urinary levels and recovery rates were determined. ASPC was administered to 1 patient with tuberculous pleurisy in the dose of 20 mg/kg by one shot intravenous injection, then the thoracic fluid level and serum level were determined. In addition, ASPC was administered to 3 children with tonsillitis, 3 with bronchitis, 40 with pneumonia, one each for pleuropneumonia, pleurisy, lung abscess, scarlet fever, staphylococcal scalded skin syndrome and purulent lymphadenitis and 2 with UTI (total 54 children), in the mean dose of 81.4 mg/kg/day t.i.d. (12 children) or q.i.d. (42 children) by one shot intravenous injection for 6 days on the average, and clinical effectiveness and bacteriological response were evaluated in these cases, and adverse reactions and abnormal laboratory findings were examined in the 60 cases which included 6 drop-out cases. After the administration of ASPC to 9 children; 10, 20 and 40 mg/kg to each of 3 children, by one shot intravenous injection, the mean serum levels reached to the peak of 58.4, 147.0 and 221.0 mcg/ml, respectively, in 5 minutes. The mean half-lives were 1.03, 1.01 and 1.23 hours, and the mean areas under the curve (AUCs) were 44.9, 94.1 and 192.9 mcg X hr/ml, respectively. A dose response was seen among the 3 dosage levels. After the administration of ASPC to 11 children; 20 and 40 mg/kg to 8 and 3 children, respectively, by intravenous drip infusion over a period of 1 hour, the mean serum levels reached to the peak of 58.2 and 114.0 mcg/ml, respectively, on completion of the administration. The mean half-lives were 1.22 and 1.09 hours, and the mean AUCs were 109.4 and 181.7 mcg X hr/ml, respectively. A dose response was observed between the 2 dosage levels. In the above mentioned each 3 cases receiving one shot intravenous injection in the dose of 10, 20 and 40 mg/kg, the mean urinary levels of ASPC reached to the peak of 1,000.0, 2,300.0 and 4,350.0 mcg/ml, respectively, at 0 approximately 2 hours after the administration, and the urinary recovery rates during the first 6 hours were 66.1, 66.5 and 56.9%, respectively.(ABSTRACT TRUNCATED AT 400 WORDS)

Sulbactam/cefoperazone (SBT/CPZ) was evaluated in the treatment of pediatric patients to have the following results: Peak serum concentrations which occurred just after the drip infusion of 20 mg/kg SBT/CPZ were 36.4 micrograms/ml and 8.6 micrograms/ml for CPZ and SBT, respectively. The half-life of CPZ was 1.91 hours, and that of SBT, 0.97 hour. Following the 40 mg/kg drip infusion, the peak serum concentration of CPZ was 79.1 micrograms/ml, and that of SBT, 27.0 micrograms/ml. The half-lives were 1.99 hours for CPZ, and 1.07 hours for SBT, respectively. In 6 hours after drip infusion of 20 mg/kg and 40 mg/kg 21.7, 37.0% of CPZ and 41.6, 85.6% of SBT were excreted in urine. Daily doses of about 50-90 mg/kg SBT/CPZ were administered by intravenous or drip infusion to 26 pediatric patients with acute infections such as lacunar tonsillitis, bronchitis, bronchopneumonia, suppurative diseases caused by Staphylococcus (staphylococcal scalded skin syndrome), purulent parotitis, cervical lymphadenitis, phlegmon and acute UTI related with ABPC/CPZ resistant beta lactamase producing E. coli. SBT/CPZ demonstrated the bacteriological effect on all the causative organisms. The clinical efficacy was also confirmed with the efficacy rate of 88.5%. No side effects were observed in all the cases though transient eosinophilia developed in 2 patients.
