A study was carried out in general practice to assess the clinical effectiveness and tolerability of the oral cephalosporin, cefuroxime axetil, in the treatment of 369 patients presenting with acute infections of the upper respiratory tract. The main diagnoses were tonsillitis, pharyngitis, sinusitis and otitis media. Patients were treated for 7 days with 1 tablet of 250 mg cefuroxime axetil twice daily. Details of fever and signs and symptoms of infection such as pain, sinus tenderness and reddening of the eardrum were recorded before and after treatment. Response was assessed by the physician on the basis of the clinical findings (the microbiological findings will be reported separately), and by patients on their satisfaction with their therapy. The results indicated an overall clinical improvement rate of 89%: all clinical parameters showed significant improvement and most patients were symptom-free when seen after treatment. Only 2 patients were classified as treatment failures and withdrawn from the study. Complete resolution of the infection was seen more often in patients with tonsillitis and pharyngitis than in those with sinusitis or otitis media. Over 80% of patients expressed their satisfaction with therapy. Adverse events reported were few, even though patients were prompted with a non-leading question, and were mainly mild in nature. The most frequently reported were diarrhoea (5%) and loose motions (3%).

BRL 25000 granules, a formulation of amoxicillin (AMPC) and the beta-lactamase inhibitor clavulanic acid (CVA) in a ratio of 2 to 1, was studied clinically and bacteriologically in pediatric infections. The in vitro antibacterial activity of BRL 25000 was superior to AMPC against beta-lactamase producing strains. The pharmacokinetics of the BRL 25000 granule were studied following oral administration to a 6 years old female and 9 years old male in the fasting state at dose levels of 10 mg/kg and 16.1 mg/kg, respectively. In the case of the female dosed at 10 mg/kg, the peak serum concentrations were found to be 6.38 micrograms/ml for AMPC and 1.83 micrograms/ml for CVA at 1 hour following administration. The elimination half-life of AMPC was 0.86 hour and that of CVA was 0.67 hour. The 4-hour urinary recovery was 61.89% for AMPC and 17.92% for CVA. In the male receiving 16.1 mg/kg, the peak concentrations were 2.55 micrograms/ml for AMPC at 3 hours following administration and 1.46 micrograms/ml for CVA at 1.5 hours following administration. The elimination half-life of AMPC was 1.59 hours and that of CVA was 1.19 hours. The 6-hour urinary recovery was 44.19% for AMPC and 30.05% for CVA. In clinical studies, the BRL 25000 granule was administered to 36 infants with upper respiratory tract infections, mainly tonsillitis, urinary tract infections etc. Good clinical efficacy was obtained in 33/36 cases (91.7%). Diarrhea and rash were occasionally noted side effects but were not severe. From the above results, it can be concluded that the BRL 25000 granule is a suitable and effective drug for use in the treatment of pediatric infections.

Fundamental and clinical studies were carried out on ceftizoxime suppository (CZX-S), and the following results were obtained in pediatrics. In 4 patients of the CZX-S 125 mg-administered group (9.4-9.9 mg/kg), the serum concentration of CZX reached a peak of 5.55 micrograms/ml on the average, 30 minutes after dosing, i.e. at the time of initial blood collection, and decreased gradually to 0.20 microgram/ml 6 hours after dosing. The half-life was 1.09 hours. In 5 patients of the CZX-S 250 mg-administered group (8.4-18.1 mg/kg), the serum concentration of CZX peaked at 7.07 micrograms/ml on the average and then gradually declined to 0.16 microgram/ml 6 hours after dosing. The half-life was 1.00 hour. The urinary recovery rate varied as widely as 6.5-38.0% in all the patients of both groups. CZX-S was given to total 19 patients; 8 patients with urinary tract infection (UTI), 3 with pharyngitis or tonsillitis, 4 with bronchitis, 2 with pneumonia, 1 with otitis media and 1 with staphylococcal scalding skin syndrome. The overall effect of CZX-S in 15 patients was "effective" or better response, with an effectiveness rate of 83.3%, except one who discontinued the drug because of side effects. CZX-S was given to most of the patients weighing 15 kg or higher in a dose of 250 mg 3-4 times a day and frequently to patients weighing less than 15 kg in a dose of 125 mg 3-4 times a day. As to side effects, slight diarrhea was encountered in 1 patient. Laboratory examinations disclosed an increase in GOT in 1 patient, which returned to normal after continual insertion of the suppository.

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.

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.

A multicenter cooperative clinical trial was carried out on S6472 (a long-acting preparation of cefaclor (CCL)) to evaluate its effectiveness and safety in the treatment of infectious diseases in the field of otorhinolaryngology. The results are as follows: The clinical efficacy of the drug could be evaluated in 114 patients. An efficacy rate of 65.8% was obtained. The efficacy rate for each disease was found to be 60.0% for acute suppurative otitis media, 12.5% for chronic suppurative otitis media and 44.4% for acute exacerbation of chronic suppurative otitis media. The overall efficacy rate for all cases of suppurative otitis media was 46.4%. The efficacy rate for acute tonsillitis was found to be 93.1%. In the treatment of acute exacerbation of chronic tonsillitis, the efficacy of the drug was rated as excellent or good in all cases. The overall efficacy rate for all cases of tonsillitis was found to be 93.9%. In the treatment of other infectious diseases, the efficacy was rated as excellent or good in all cases. When the cases by resistant organisms to CCL were excluded from the evaluation, the overall efficacy rate of the drug was found to be 74.2%. The bacteria could be identified in 106 cases. Regarding the bacteriological efficacy of single infections, its bacterial elimination rate was found to be 81.1% for Gram-positive bacteria including S. aureus, S. epidermidis, etc., while it was 42.9% for Gram-negative bacteria. The overall elimination rate of bacteria in single infections was 73.1%. The bacterial elimination rate for mixed infections was found to be 85.7%, whereas it was 76.8% when the single and mixed infections were combined. Regarding side effects, 1 case each of diarrhea, soft stool and rash, or 3 cases in total (2.4%), were recorded in a total of 123 patients. However, the severity of each side effect was mild. Regarding abnormal laboratory findings, there were 1 case each of an increase in S-GPT, leukopenia and complication of eosinophilia and thrombocytopenia, or 3 cases in total (7.0%). Each of these adverse reactions was, however, transient in nature, and no serious cases were observed. On the basis of the above results, it was concluded that S6472 can provide sufficient clinical efficacy when it is administered at daily dosage of 750 mg or 1,500 mg in 2 divided doses after the breakfast and dinner.

The penetration of aztreonam (AZT), a new synthetic monobactam, into cerebrospinal fluid (CSF) and the clinical studies for bacterial infections were carried out. The following results were obtained. The concentrations of AZT in CSF were less than 0.31 microgram/ml and 0.42 microgram/ml, respectively, at 1 hour after intravenous administration of 34 mg/kg and 71 mg/kg in 2 cases of aseptic meningitis at the acute stage. The concentration of AZT in CSF was 6.9 micrograms/ml at 1 hour after intravenous administration of 100 mg/kg in 1 case of purulent meningitis at the acute stage and was 0.62-0.98 micrograms/ml even at the recovering stage. At each stage, its concentration was more than the minimum inhibitory concentration of E. coli (0.10, less than 0.05 microgram/ml; at inoculum size of 10(8), 10(6) cells/ml). Clinical efficacy of AZT was good in 2 cases of purulent meningitis, excellent in 1 case of septicemia, excellent in 5 cases of urinary tract infection, excellent in 1 case and good in 3 cases out of 4 cases of gastroenteritis, excellent in 4 cases and poor in 2 cases out of 6 cases of pneumonia and bronchitis, excellent in 2 cases and good in 1 case out of 3 cases of tonsillitis. No side effects and no abnormal laboratory findings were observed except 1 case of mild diarrhea out of 21 cases.

Twenty-eight pediatric patients were treated with ceftriaxone (Ro 13-9904, CTRX) in the doses ranging from 8.75 to 25 mg/kg every 12 hours for 3.5 to 11.5 days, and the clinical efficacy and side effects were evaluated. Among the 21 children with bacterial infections including pneumonia, acute bronchitis, otitis media, tonsillitis and urinary tract infections, the results were excellent in 9, good in 11, and fair in 1 patient. Out of the 28 patients, 2 patients had diarrhea, 3 patients had slightly elevated serum concentrations of transaminases, and 2 patients showed eosinophilia. The serum concentrations of CTRX in 5 children ranged from 50.0 to 93.8 micrograms/ml (mean 75.0 micrograms/ml) at 15 minutes and from 10.2 to 15.6 micrograms/ml (mean 13.4 micrograms/ml at 6 hours after 10 mg/kg intravenous bolus injection of CTRX. The serum half-lives were from 2.61 to 8.30 hours (mean 6.16 hours), and urinary recovery rates were from 43.3 to 58.0% (mean 48.5%) during 0-6 hours and from 52.0 to 66.1% (mean 59.4%) during 0-12 hours. After 20 mg/kg intravenous bolus injection of CTRX in 4 children, the serum concentrations of CTRX were from 118.8 to 162.5 micrograms/ml (mean 139.1 micrograms/ml) at 15 minutes and from 18.0 to 21.1 micrograms/ml (mean 19.2 micrograms/ml) at 6 hours. The serum half-lives were 4.07 to 6.34 hours (mean 5.13 hours), and urinary recovery rates were 38.6 to 51.1% (mean 45.4%) during 0-6 hours and from 54.8 to 64.0% (mean 59.0%) during 0-12 hours. Patients with impairment of renal function were excluded from this pharmacokinetic study.

Pharmacokinetics and clinical effects of ceftizoxime (CZX), a new cephalosporin antibiotic, were investigated and following results were obtained. 1) Ceftizoxime was given by intravenous injection or drip infusion for 1 hour at a single dose of 30 mg/kg. After intravenous injection, the mean peak serum level of 3 children was 95.9 mcg/ml at 15 minutes and half-life time was 1.18 hours. After 1 hour drip infusion, the mean peak serum level of 3 children was 79.5 mcg/ml at the end of infusion and half-life time was 1.20 hours. The urinary level was high and the mean urinary recovery rate was 69.6% and 63.4% up to 6 hours after intravenous injection and 1 hour drip infusion, respectively. 2) CZX was administered in dose of 39--76 mg/kg to 7 pediatric patients (4 cases of purulent meningitis, 2 of septicemia with purulent meningitis, and 1 of aseptic meningitis) by a single intravenous injection. In patients with purulent meningitis, passage into the cerebrospinal fluid was relatively as good as 30% of serum level at the same time in the presence of remarkable signs of inflammation, but poor in cases of mild inflammation or aseptic meningitis. 3) Cerebral puncture fluid level in 1 patient with cerebral abscess was as good as 65.5% of serum level at the same time. 4) CZX was given to 28 cases of respiratory tract infection, 1 of tonsillitis with otitis media, 6 of scarlet fever, 1 each of maxillary sinusitis and bacterial endocarditis, 6 of purulent meningitis, 2 of septicemia, 5 of septicemia suspected, 2 of septicemia with purulent meningitis, 1 each of osteomyelitis, typhoid fever, peritonitis and biliary tract infection, 16 of urinary tract infection, 14 of skin and soft tissue infection, and 1 of external otitis, totaling 87 cases. The mean daily dose of 101.6 mg/kg was administered for an average of 10 days mainly by intravenous injection 4 times daily. Clinical results obtained were excellent in 34 cases, and good in 46. Bacteriological effectiveness rate was 100%. As for side effects, fever, fever with rash, fever with cough and diarrhea appeared in 1 each case out of 182 cases including 95 drop out cases. As for laboratory findings, eosinophilia, thrombocytopenia, elevation of GOT, that of GOT with GPT, and that of GOT with LDH appeared in 10, 2, 2, 3 and 1 cases, respectively.

Laboratory and clinical studies were performed as follows on ceftizoxime (CZX), a new cephalosporin antibiotic. 1. Susceptibility of clinically isolated bacteria to CZX and cefotiam (CTM) or sulbenicillin (SBPC). Antibacterial activities of CZX and CTM were compared against S. aureus, E. coli, K. pneumoniae, E. cloacae, H. influenzae and E. aerogenes; CZX was compared with SBPC against Ps. aeruginosa. CZX and CTM were nearly equal in activity against S. aureus, but CZX was found to be more active than CTM by 1--10 tubes against E. coli, K. pneumoniae, E. cloacae, H. influenzae and E. aerogenes. Against Ps. aeruginosa, CZX and SBPC were nearly equal in activity. 2. Serum concentration and urinary recovery. Serum concentrations of CZX were measured in 6 patients given CZX for prophylactic purpose during cardiac catheterization. In 2 patients given 20 mg/kg of CZX intravenously, the average serum concentration was 38.9 micrograms/ml at 30 minutes after intravenous bolus injection. In 3 patients given 10 mg/kg of CZX by intravenous drip infusion, the peak average serum concentration was 28.1 micrograms/ml at the end of infusion. Urinary recovery in 2 patients tested was 81.1% and 92.5% until 6--7 hours after intravenous bolus injection. 3. Clinical efficacy. CZX was given intravenously to 24 patients in doses of 30--111 mg/kg (57.1 mg/kg on an average) t.i.d. or q.i.d. for 3--16 days (5.5 days on an average): 1 with lacunar tonsillitis, 4 with acute bronchitis, 12 with pneumonia, 2 with enterocolitis, 2 with soft tissue infection, 2 with lymphadenitis and 1 with UTI. The overall efficacy rate was 95.8%, i.e., efficacy was excellent in 10 (41.7%), good in 13 (54.2%), and poor in 1 (4.2%). Bacteriological efficacy was excellent, i.e. 21 of the 23 strains disappeared. One patient had mild and transient diarrhea, but no other laboratory abnormalities were observed during treatment. The above results suggest that CZX is 1 of the most useful antibiotics for treating pediatric infections, especially due to Gram negative bacteria.
