The new antibiotic, sulbactam/ampicillin (SBT/ABPC) was administered to 25 children. The results obtained are summarized as follows. 1. In 5 cases of children administered with SBT/ABPC (30 mg/kg) by intravenous drip infusion for 30 minutes, the mean values of T 1/2 (beta) were 0.94 hour (SBT) and 0.86 hour (ABPC) and the mean 6.5 hour urinary excretion rates were 64.2% and 42.9%, respectively. 2. The antibiotic was administered to a total of 25 patients with bronchopneumonia, pneumonia, bronchitis, cervical lymphadenitis, tonsillitis, streptococcal infection, urinary tract infection, felon, periappendicular abscess, sepsis or purulent meningitis. Response to the treatment were excellent in 17 cases, good in 7, fair in 1, and poor in none. The efficacy rate was 96%. From our results, this drug appears to be particularly effective against bronchopneumonia, bronchitis and urinary tract infection. 3. Eruption occurred in 1 of 25 patients and elevation of eosinophil, GOT/GPT, platelet in 3 and descent of WBC in 1 were observed, but these were transient. These results showed that SBT/ABPC is a drug which can be safely used in the pediatric field as well as for adults.

Experimental and clinical study of cefodizime (CDZM, THR-221), a newly developed cephem antibiotic, was done in the field of pediatrics and the results obtained are summarized as follows: 1. Serum levels and urine excretion were examined after 60-minute drip infusion of CDZM at a dose level of 10 mg/kg to 1 patient, at 20 mg/kg to 4 and at 40 mg/kg to 1. Peak levels in serum were 66.3 micrograms/ml for the 10 mg/kg dose occurring 1 hours after the dose, 118.1 micrograms/ml (mean) for 20 mg/kg, 259.2 micrograms/ml for 40 mg/kg, thus a dose-response was observed. T 1/2's (beta phase) were between 1.17 and 1.69 hours. Urinary recovery rates of the drug were between 71.5% and 98.0% in the first 8 hours after administration. 2. The concentration in the cerebrospinal fluid was 0.76 microgram/ml and the serum level was 380.67 micrograms/ml at 15 minutes after intravenous administration of 433 mg of CDZM to a patient with purulent meningitis. 3. The clinical efficacy rate was 95.2% in a total of 21 cases, i.e., 1 purulent meningitis, 10 respiratory tract infection, 3 whooping cough, 5 urinary tract infection, 1 purulent infection of soft tissues and 1 acute thyroiditis. Diarrhea occurred in 1 case as adverse reactions. Abnormal changes in laboratory test results occurred as 1 case each of slightly elevated GOT.GPT and GOT.

Therapeutic effects of cefodizime (CDZM, THR-221), a new cephalosporin having a methoxyimino group, were examined in various infectious diseases in children. Clinical efficacy rates were 100% (3/3) in pneumonia, 100% (5/5) in acute bronchitis, 75% (3/4) in upper respiratory infections and 100% (1/1) in each of a croup and a mixed infection with Streptococcus pyogenes and staphylococcal impetigo. Hence, the overall efficacy rate was 92.9% (13/14). Adverse effects were observed in 2 cases, i.e. exanthema provably due to drug allergy in 1 case and a slightly elevated GPT in another. Changes in serum concentrations and urinary excretion of CDZM were examined in a child with no infection. T 1/2 values obtained were 124.5 minutes (bioassay) and 143.4 minutes (high performance liquid chromatography (HPLC]. Eight hour recovery rates in urine were 62.9% (bioassay) and 65.4% (HPLC). CDZM was considered to be a safe and useful drug in treating various infectious diseases in children.

Laboratory and clinical studies on cefodizime (CDZM, THR-221), a newly developed cephem antibiotic, were done. The results obtained are summarized as follows: 1. Absorption and elimination were examined in a total of 5 cases including a case of 10 mg/kg intravenous drip infusion for 30 minutes, 2 cases of 20 mg/kg rapid intravenous injection and 2 cases of 40 mg/kg drip infusion for 30 minutes. Maximum serum levels were attained immediately after drip infusion or rapid injection. Cmax's were 119.2 micrograms/ml for 10 mg/kg, 374.9 micrograms/ml or 255.7 micrograms/ml for 20 mg/kg, and 321.3 micrograms/ml or 431.8 micrograms/ml for 40 mg/kg. These values were determined using an high performance liquid chromatography (HPLC) method. In general, values using the bioassay were higher than those with the HPLC method. T 1/2 (beta)'s were between 1.74 and 1.93 hours using HPLC, and between 1.77 and 2.24 hours using bioassay. Urinary recovery rates were examined in 3 out of 5 cases. Cumulative urinary recovery rates were 57.9-90.6% with HPLC method and 50.4-88.0% with bioassay in a period of 0-8 hours after administration. 2. Clinical efficacy was evaluated in a total of 22 cases including 14 cases of respiratory tract infections, 5 cases of urinary tract infections and 3 cases of cellulitis. Clinical efficacy rate was 95.2%. Bacteriologically, pathogenic organisms were eradicated in 90.0%. As adverse reactions, 1 angular stomatitis, 1 diarrhea and 1 loose stool were noted. Abnormal laboratory test values detected were 1 case of increased GPT and 1 case of increased GOT and GPT.

A pharmacokinetic and clinical study of ceftizoxime (CZX), a newly developed cephem antibiotic intended for parenteral use, was conducted in premature and newborn infants, and resulted in the following findings. 1. Pharmacokinetics (1) Average serum half-lives (T 1/2) following a one shot intravenous dose of 20 mg/kg of CZX to mature and premature newborn infants in age groups of 0-3, 4-7, 8-14, and 15-30 days were: 4.14, 3.01, 2.57, and 1.98 hours (for mature infants) and 5.26, 4.59, 3.71, and 2.64 hours (for premature infants), respectively, decreasing with ages in days of the infants. (2) Average T 1/2's after a one shot 10 mg/kg dose was similar to that after a 20 mg/kg dose. Serum concentrations of CZX were dose-dependent. (3) T 1/2 after 1-hour intravenous drip infusion revealed a same trend after one shot injection. (4) Urinary in the first approximately 6 hours recoveries following a 20 mg/kg one shot dose to mature and premature newborn infants were as follows: 35% (0-3 days old) and 45-55% (4 days old and older) in mature infants and 30% (0-3 days old) and 45% (4 days old and older) in premature infants. 2. Therapeutic effectiveness (1) The subjects examined were 112 newborn infants consisting of 83 with infections and 29 who received CZX for prophylaxis. The 83 infants had 86 cases of infections, which were classified as A, when the causative organisms were identified and as B, when the causative organisms were not identified. Rates of therapeutic effectiveness were 95.0% for group A and 95.7% for group B. Bacteriological effectiveness were studied on 41 strains isolated from group A, and were as high as 89.5% for Gram-positive organisms and 95.5% for Gram-negative organisms. The rate of successful prophylaxis for the 29 infants was 96.6%. (2) Side effects did not occur among the 120 newborn infants. Laboratory tests with abnormalities included leukopenia, neutropenia, eosinophilia, thrombocytosis and increased GOT or GPT. These pharmacodynamic and clinical findings have fully substantiated the satisfactory therapeutic usefulness of CZX in both the treatment and prevention of neonatal infections in the usual dose of 20 mg/kg, which is to be given b.i.d. for infants up to 3 days old; b.i.d. or t.i.d. for infants 4 to 7 days old, and t.i.d. or q.i.d. for infants 8 days old and older. The drug can be given in a daily dose as high as 120 mg/kg when infection is severe.

Fundamental and clinical studies on BRL 25000 granules, containing 2 parts amoxicillin (AMPC) and 1 part clavulanic acid (CVA) (a beta-lactamase inhibitor) were carried out in the pediatric field. Serum concentrations and urinary excretion rates were determined after oral administration of BRL 25000 granules at a dose of 20 mg/kg to 2 children. The mean peak serum concentrations of AMPC and CVA were 4.89 and 2.85 micrograms/ml at 1 hour after administration, with serum half-lives (T 1/2) of 1.15 and 0.89 hours respectively. Mean cumulative urinary excretion rates of AMPC and CVA in the 6 hours after administration were 24.91% and 10.19%, respectively. BRL 25000 granules were also administered at daily doses of 25.1-60.4 mg/kg in 3 divided doses, to 20 pediatric patients with bacterial infections (4 acute tonsillitis, 2 acute pharyngitis, 3 suspected scarlet fever, 3 acute bronchitis, 8 urinary tract infection). The efficacy rate was 100% clinically and 70% bacteriologically. No adverse reactions were observed, however, abnormal laboratory findings were observed in 4 cases (slight elevation of GOT in 2, GPT in 1, eosinophilia in 1).

T-1982 (cefbuperazone), a new injectable cephamycin antibiotic, was employed for bacterial infections in children, and the following results were obtained. 1. When administered intravenously at a dose of 20 mg/kg to a 6-year-old female child, serum levels were 62 micrograms/ml at 30 minutes, 39 micrograms/ml at 1 hour, 17.6 micrograms/ml at 2 hours, 6.8 micrograms/ml at 4 hours and 2.9 micrograms/ml at 6 hours with serum half-life (T 1/2) of 76 minutes. Urinary excretion rates were 41.0, 5.3% and 2.4% respectively at 0-2, 2-4 hours and 4-6 hours, and urinary levels were 820 micrograms/ml, 182 micrograms/ml and 310 micrograms/ml, respectively. The total urinary recovery within 6 hours was 48.7%. 2. A total of 11 cases of pediatric infections was treated with T-1982. The clinical efficacy evaluated for 9 cases, excluding 2 cases of non-bacterial infections, was as follows; excellent in 4, good in 1 out of 5 cases of pneumonia, good in 1 case of cervical purulent lymphadenitis, and excellent in 1, good in 1, poor in 1 out of 3 cases of urinary tract infection. 3. As side effect, mild diarrhea in 1 case and slight elevation of GOT, GPT in 2 cases were observed. 4. These results suggest that T-1982 is of good use for bacterial infections in children and the expected efficacy is obtained at a dose of 20 mg/kg 3 times a day.

Laboratory and clinical studies on ceftazidime ( CAZ ), a new cephem antibiotic, were carried out in the field of pediatrics. The results were as follows: Antibacterial activities of CAZ against clinically isolated strains of S. pneumoniae, H. influenzae, E. coli and P. aeruginosa were compared with those of cefotaxime (CTX), ceftizoxime (CZX), latamoxef ( LMOX ), cefoperazone (CPZ) and cefmetazole (CMZ), and also with cefsulodin (CFS) and gentamicin (GM) against P. aeruginosa. Against S. pneumoniae and H. influenzae, CAZ was almost as active as CTX, CZX and CPZ. Against E. coli, it was almost as active as CTX, CZX and LMOX . Against P. aeruginosa, it was almost as active as CFS and GM. Serum concentrations and urinary excretion rates after intravenous bolus injection of CAZ at doses of 20 mg/kg and 10 mg/kg for 5 minutes in each 2 cases (4 cases in total) were determined. The mean serum concentrations of CAZ were 78.9 and 52.0 micrograms/ml at 15 minutes, 38.5 and 27.4 micrograms/ml at 1 hour, and 6.5 and 4.8 micrograms/ml at 4 hours, with serum half-lives (T 1/2) of 1.39 and 1.80 hours respectively. Mean cumulative urinary excretion rate within 6 hours after administration was 84.6%. In a patient with chronic renal failure, serum half-life was 3.22 hours and urinary excretion rate within 6 hours was 22.8% (after intravenous bolus injection of CAZ at a dose of 10 mg/kg). CAZ was administered at a dose of 55.5 mg/kg by intravenous bolus injection to a child with purulent meningitis. The levels of CAZ in the cerebrospinal fluid (CSF) at 1 hour after administration were 2.7-38.9 micrograms/ml with CSF/Serum ratios of 3.2-28.8%. Forty-two pediatric patients with various bacterial infections (pyelonephritis 14, tonsillitis 1, bronchopneumonia 3, pneumonia 17, purulent meningitis 1, bacteremia 2, SSSS 1, enterocolitis 3) were treated with CAZ at a daily dose of 49-222 mg/kg t.i.d. or q.i.d. (as a rule 60 mg/kg t.i.d.). The efficacy rate was 97.6% clinically and 97.8% bacteriologically. No adverse reactions were observed except 1 case with mild diarrhea. Abnormal laboratory findings were also only mild; eosinophilia in 1, slight elevation of GOT in 5 and that of GOT & GPT in 3 cases. These results indicate the usefulness of CAZ in the treatment of bacterial infections in children.

Ceftazidime ( CAZ ), a new injectable cephem antibiotic, was used for treatment of infections in children, and the following results were obtained. After an intravenous injection of CAZ at a dose of 20 mg/kg, the mean blood levels in 2 patients were 41.5 micrograms/ml at 30 minutes, 18.1 micrograms/ml at 2 hours and 2.55 micrograms/ml at 6 hours, with the half-life (T 1/2) of 1.37 hours. In a 22-day-old baby with meningitis given CAZ intravenously at a dose of 43.5 mg/kg, the blood levels were 100 micrograms/ml at 30 minutes, 68 micrograms/ml at 2 hours and 25 micrograms/ml at 6 hours, with the half-life (T 1/2) of 2.96 hours. After intravenous administration of CAZ in doses ranging from 35.7 to 50 mg/kg, CSF concentrations ranged from N.D. to 6.3 micrograms/ml in 3 patients with purulent meningitis, although 19 micrograms/ml at 1 hour and 13 micrograms/ml at 2 hours in 1 patient after intravenous administration of 46.7 mg/kg. In patient with mumps meningitis, CSF concentrations were undetectable after intravenous administration of 35.7 mg/kg. Seventeen patients (each 1 patient with lymphadenitis, tonsillitis and septicemia, each 2 patients with pneumonia, bronchiectatic bronchitis, pyothorax and purulent meningitis, each 3 patients with pyelonephritis and enteritis) were treated with CAZ intravenously, at the daily doses of 178.2 mg/kg and 200 mg/kg in 4 divided doses in patients with meningitis and 44.1 to 103.4 mg/kg in 3 divided doses in patients with other infections (two of them were given by intravenous drip infusion for 30 minutes). The clinical responses were excellent or good in all the patients except for 1 case of Salmonella enteritis (poor) and 1 case of Campylobacter enteritis (poor). The efficacy rate was 88.2%. It was noteworthy that the clinical response was excellent in 1 case of septicemia with P. aeruginosa with leukemic stage of malignant lymphoma and in 2 cases of purulent meningitis. As side effects, fever, eruption, leukocytopenia, elevation in GOT and positive CRP considered to be allergic, were observed on day 16 of administration in 1 case of pyothorax. These symptoms disappeared by discontinuance of administration. In addition, there were elevation in GOT and GPT in 2 cases and elevation in GOT in 2 cases and elevation in GPT in 1 case; they were all mild or transient, and there was nothing to be worried about.(ABSTRACT TRUNCATED AT 400 WORDS)

Pharmacokinetics and clinical studies on the perinatal use of latamoxef (LMOX, Shiomarin), a new parenteral oxacephem antibiotic, were carried out and the results obtained were as follows: After LMOX was intravenously given to mother at a dose of 1 g, the umbilical cord serum concentration of LMOX reached to peak with 18.4 micrograms/ml in 1 hour 20 minutes and its concentration was higher than the maternal serum after 2 hours 25 minutes and decreased gradually (T 1/2 beta = 1.61 hours). The materno-fetal transfer of LMOX was 71.0%. LMOX showed the good transfer as well as other cephalosporins. After LMOX was intravenously administered to mother at a dose of 1 g, LMOX concentration in milk wasn't detectable up to 12 hours. LMOX was intravenously administered to 18 cases with premature rupture of membrane, at a daily dose of 2 g for 3--6 days. The prophylactic effects were observed in all cases, both mother and neonate. No adverse effects were observed in mother except for 1 case with low grade abnormality of S-GPT, transiently. We observed 3 neonates with jaundice (total bilirubin greater than or equal to 17.0 mg/dl) probably not related to LMOX. It is concluded that LMOX is less toxic, safe and clinically useful antibiotic for the treatment of perinatal infections.
