Pharmacokinetic and clinical studies on cefmenoxime (CMX) in neonates and infants were conducted. 1. CMX 20 mg/kg was administered by intravenous bolus injection to 6 neonates (with ages 2 to 20 days) and 5 infants (with ages 36 to 107 days) and its serum concentration and urinary excretion rates were determined. In the neonates, serum concentrations of CMX after intravenous administration reached peak levels of 48.2 to 90.7 micrograms/ml (mean 70.4 +/- 14.3 micrograms/ml) in 1/4 hour, then declined with half-lives of 1.27 to 5.19 hours (mean 2.28 +/- 1.56 hours), and were 3.6 to 16.9 micrograms/ml (mean 8.3 +/- 6.0 micrograms/ml) at 6 hours. In the infants, serum concentrations at 1/4 hour were 67.5 to 111.0 micrograms/ml (mean 95.5 +/- 18.0 micrograms/ml); half-lives were 0.64 to 0.94 hour (mean 0.81 +/- 0.13 hour); and the serum concentrations at 6 hours were 0.2 to 1.1 micrograms/ml (mean 0.7 +/- 0.4 micrograms/ml). Mean peak serum concentrations in the neonates tended to be lower than those in the infants, but higher than those in children. Regarding the age differences of serum concentrations due to age in the neonates, their peak levels tended to be lower in younger ones. Half-lives were shorter in older subjects and, in early infancy, approached values observed in children. Urinary recovery rates in the first 6 hours after intravenous administration ranged from 43.6 to 87.5% (mean 61.6 +/- 14.6%) in the neonates and from 52.1 to 90.8% (mean 78.0 +/- 15.1%) in the infants. Thus, recovery rates were high even in younger subjects and tended to be higher in older subjects. 2. CMX was administered to 27 neonates and 4 infants to investigate its clinical effect, bacteriological effect and side effects. Clinical efficacy ratings of the drug in 19 neonate cases that could be evaluated (1 with purulent meningitis, 2 with suspected septicemia, 1 with acute bronchitis, 12 with acute pneumonia, 1 with impetigo, 1 with periumbilical abscess and 1 with acute pyelonephritis) were "excellent" in 14 cases, "good" in 4, and "poor" in 1. The efficacy rate covering "excellent" and "good" was 94.7%. In 4 infants (2 with acute pneumonia, 1 with periumbilical abscess and 1 with acute pyelonephritis), "excellent" was obtained in 2 cases and "good" in 2 cases. Thus, all the cases showed "good" or higher ratings. Bacteriologically, 1 strain of Staphylococcus aureus and 3 strains of Escherichia coli in neonates were eradicated while, in infants, 1 strain of S. aureus persisted but 1 of E. coli was eradicated.(ABSTRACT TRUNCATED AT 400 WORDS)

T-1982 (cefbuperazone), a new injectable cephamycin antibiotic, was studied for its antibacterial activity, concentration in serum and urine, penetration into cerebrospinal fluid (CSF) as well as clinical application. The following results were obtained. 1. Antibacterial activity: The susceptibilities of clinically isolated K. pneumoniae, E. coli and E. cloacae to T-1982 were superior to those of CEZ CMZ, and ABPC. T-1982 seemed to be useful for various infections due to Gram-negative rods. 2. Concentration in serum and urine: Subjects were 10 children with congenital heart failure but no abnormal renal and liver functions. T-1982 was given intravenously to 3 groups at 200 mg/kg by one shot (4 cases), 20 mg/kg by 1 hour drip infusion (3 cases) and 10 mg/kg by 1 hour drip infusion (3 cases). The half-lives were 60, 78 and 85 minutes, respectively. 3. Penetration into cerebrospinal fluid: Three children with malignant tumor were injected 20 mg/kg intravenously. A small amount of T-1982 was penetrated into CSF. 4. Clinical efficacy: T-1982 was administered daily 40-116 mg/kg t.i.d. or q.i.d. for 2-14 days to 17 children comprising 1 bronchopneumonia, 1 bronchitis, 4 tonsillitis, 1 lymphadenitis, 1 sepsis, 1 pharyngitis, 1 impetigo, 1 acute sinusitis and 6 pyelonephritis. Clinical efficacy was excellent in 10, good in 2, fair and poor in 3, and the efficacy rate was 70.6%. Bacteriological effect was as follows; eradicated in 9 cases and unknown in 8 cases. As side effect, GOT and GPT elevations unrelated to the drug were observed in 2 cases. Other abnormal findings were not found. T-1982 seems to be safe antibiotic in the field of pediatrics.

Clinical efficacy of cefroxadine dry syrup, a new oral cephalosporin antibiotic, was evaluated in children, and the following results were obtained. 1. Three children were given a single oral dose of about 10 mg/kg of the drug when fasting, and its blood concentrations were determined. Blood concentrations were maximum at 30 approximately 60 minutes, i.e., 16.9 approximately 18.2 microgram/ml, and markedly low at 4 hours. 2. Thirty-six patients with the following diseases were tested with 23.1 approximately 44.4 mg/kg/day of the drug in 3 to 4 divided doses; 21 patients with lacunar tonsillitis, 2 with tonsillitis, 1 with scarlet fever, 4 with bronchitis and tonsillitis, 2 with cystitis, 4 with pyelonephritis, 1 with impetigo and 1 with probable Mycoplasma pneumonia. An overall efficacy rate in 35 patients excluding the last mentioned case was 91.4%, i.e., excellent in 20, good in 12 and poor in 3, and an eradication rate of the causative organisms was 88.9%. 3. Adverse reactions noted were diarrhea in 1 patient, eruption and diarrhea in 1 transient neutropenia in 1, eosinophilia in 3 and an elevation of GOT and GPT in 1. None were significant. 4. Taste and flavor of the drug was considered to be well palatable to children. 5. Taking into consideration of the results of fundamental evaluation of the drug, cefroxadine dry syrup is considered to be a potent new antibiotic in children, and the recommended dose will be 10 mg/kg 3 to 4 times a day.

Cefuroxime is the first commercially-available second-generation cephalosporine to be widely used in therapy; it is a semi-synthetic cephalosporin obtained from the 7-cephalosporanic acid nucleus of cephalosporin C. Cefuroxime axetil is the acetoxyethyl ester of cefuroxime. The majority of micro-organisms associated with respiratory infections are highly sensitive to cefuroxime. These include Haemophilus influenzae, Streptococcus pneumoniae, Streptococcus pyogenes and the other streptococci (excluding group D streptococci), and Moraxella catarrhalis. Bacteria sensitive to cefuroxime include the enterobacteria (Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Salmonella and Shigella and Straphylococcus aureus (methicillin-sensitive strains). The pharmacokinetic studies show that the maximum plasma concentration of cefuroxime after oral administration of 250 mg and 500 mg of cefuroxime axetil after a meal are respectively 4.6 and 7.9 mg/l. The absolute bioavailability of tablets is 68% (extremes 63-73%) after oral administration of 500 mg cefuroxime axetil. The protein binding is 33+/-5.7%. Tissue diffusion was studied in the interstitial fluid, the bronchial mucosa, the tonsils, and the bronchial secretions. Cefuroxime axetil is available as capsule-shaped tablets containing 125, 250 or 500 mg. An oral suspension dosage form for paediatric purposes is also available as granules in multidose bottles and sachets. Constitution gives a suspension containing 125 mg or 250 mg cefuroxime (as cefuroxime axetil). Cefuroxime axetil is indicated for the treatment of infections caused by susceptible bacteria. Indications include: lower respiratory tract infections (e.g., acute and chronic bronchitis and pneumonia); upper respiratory tract infections (e.g., ear, nose and throat infections such as otitis media, sinusitis tonsillitis and pharyngitis); genito-urinary tract infections (e.g., pyelonephritis, cystitis and urethritis, gonorrhoea, acute uncomplicated gonococcal urethritis and cervicitis); and skin and soft tissue infections (e.g., furunculosis, pyoderma and impetigo). For most infections, a dose of 250 mg twice daily is appropriate. In some urinary tract infections, 125 mg twice daily has been shown to be effective. If pneumonia is suspected or in more severe lower respiratory tract infection, doses of 500 mg bd should be used. Uncomplicated gonorrhoea has been shown to respond to a single 1-g dose of cefuroxime axetil. Adverse reactions to cefuroxime have generally been mild and transient in nature (gastrointestinal disturbances, including diarrhoea, nausea and vomiting).
