A newly developed macrolide clarithromycin (TE-031, A-56268), with antibacterial spectrum and antibacterial activity nearly equal to those of erythromycin (EM), shows beneficial characteristics such as a higher blood level, higher recovery rate in urine, and better penetration into each tissue than conventional macrolides (MLs). TE-031 has been studied in adults against various infections and proved to be useful. The present paper describes the results of a study in children to examine the usefulness of TE-031 granules and tablets with a potency of 50 mg. TE-031 granules were administered to 132 children with ages from 6 months to 13 years and 10 months. Excluded from the evaluation were 12 cases in which clinical effects were deemed unevaluable. The evaluable subjects consisted of 1 case with pharyngitis, 3 with tonsillitis, 9 with acute bronchitis, 19 with pneumonia, 19 with mycoplasmal pneumonia, 2 with scarlet fever, 20 with Campylobacter enteritis, 11 with impetigo, 2 with subcutaneous abscess, 18 with primary atypical pneumonia and 16 with acute enteritis of unidentified pathogens; a total of 120 subjects. An average daily dose of TE-031 was 25.9 mg/kg, divided into 3 doses except 1 case with 2 daily doses and lengths of the treatment averaged 7 days. TE-031 tablets each containing 50 mg potency, were administered to 49 subjects with ages from 3 year and a month to 14 years consisting of 8 cases with pharyngitis, 1 with tonsillitis, 1 with acute bronchitis, 4 with pneumonia, 14 with mycoplasmal pneumonia, 4 with scarlet fever, 5 with Campylobacter enteritis, 7 with impetigo, 1 with atypical pneumonia, 1 with Salmonella gastroenteritis and 3 with acute enteritis caused by unidentified pathogens, at an average daily dose of 13.5 mg/kg dived into 2-4 doses (2 doses/day for 12 cases, 3 doses for 32, 4 doses for 5) for 7 days on the average. In addition to examine the clinical and bacteriological effects of the 2 dosage forms of TE-031, minimum inhibitory concentrations (MICs) were determined for 9 antibiotics consisting of 5 MLs including TE-031, EM, josamycin (JM), midecamycin acetate (MDM acetate), and rokitamycin (RKM), 3 penicillins including ampicillin (ABPC), methicillin, cloxacillin and 1 cephem antibiotic, cefaclor (CCL), against 29 strains consisting of 12 strains of Staphylococcus aureus, 7 of Streptococcus pyogenes, 2 of Streptococcus pneumonia 2 of Haemophilus influenzae and 6 of Campylobacter jejuni, out of 71 strains of pathogens or possible pathogens that had been isolated from the cases given TE-031.

Rokitamycin (RKM), a newly developed macrolide antibiotic with a 16-membered ring, dissolves well under acidic conditions. It has been improved over other macrolides to minimize individual variations in its absorbability. We measured, using the GA-test, variations in gastric acidities of 43 children with ages between 1 to 14 years, and investigated the relationship between gastric acidities and pharmacokinetic values. Also activities (expressed in MICs) of antimicrobial agents were studied against clinically isolated 229 bacterial strains using an inoculum size of 10(6) cells/ml. Tested organisms included Streptococcus pyogenes (77 strains), Streptococcus agalactiae (29), Streptococcus pneumoniae (2), as Gram-positive cocci, and Haemophilus influenzae (1), Haemophilus parainfluenzae (1), Bordetella pertussis (12), Salmonella sp. (4) and Campylobacter jejuni (103) as Gram-negative bacilli. Against stock strains of bacteria, MICs of 10 drugs (RKM, erythromycin (EM), josamycin (JM), midecamycin (MDM), midecamycin acetate (MOM), clindamycin (CLDM), amoxicillin (AMPC), cefaclor (CCL), minocycline, ofloxacin (OFLX] were determined. Against isolates from patients who underwent treatment with RKM, MICs of only 4 drugs (RKM, EM, JM, MOM) were determined. Measurements were made on plasma and urinary concentrations of RKM and its urinary recovery rates after patients including 6 boys with ages between 5 years 1 month and 11 years 6 months were administered with RKM (dry syrup). Two groups of 6 boys were administered between meals with RKM at dose levels of 5 and 10 mg/kg, respectively. Clinical and bacteriological effects of RKM were evaluated for 175 patients including 5 cases of pharyngitis, 3 tonsillitis, 32 pneumonia, 17 mycoplasmal pneumonia, 34 atypical pneumonia, 28 streptococcal infections, 29 Campylobacter enteritis, 4 Salmonella gastroenteritis, and 23 enteritis due to unknown organisms. Five drop-out cases were excluded from the evaluations. In the evaluable cases, an average dose level used was 31.8 mg/kg/day, with a daily dose divided into 3 to 4 administrations and with an average treatment duration of 9 days. Adverse reactions of RKM and its effects on laboratory test values were investigated in these patients including the drop out cases. Obtained results of these studies are summarized below. 1. The GA-test produced pH values indicating that amounts of gastric acid were mostly either normal or high in 42 of the 43 subjects tested (97.7%), and only one low acid case (2.3%) was observed.(ABSTRACT TRUNCATED AT 400 WORDS)
