Tazobactam/piperacillin (TAZ/PIPC) was given intravenously to 15 children with acute bacterial infections including 1 with purulent tonsillitis, 11 with pneumonia, 3 with acute pyelonephritis (2 cases are omitted from evaluation because of Mycoplasma pneumonia and intramuscular injection of gammaglobulin) Daily dosages per kg bodyweight ranging from 132 to 156 mg were given in 3 divided doses per day for 4 to 7 days. Clinical responses were excellent in 7 (54%), good in 6 (46%), fair and poor in 0, with an overall efficacy rate of 100%. Good bacterial responses were obtained in all of the 8 cases from which pathogens were identified. Any side effect was not observed. The above results suggest that TAZ/PIPC is a useful new antibiotic for the treatment of bacterial infections in children.

Pharmacokinetic, bacteriological and clinical studies were performed in pediatrics on tazobactam/piperacillin (TAZ/PIPC), a combined drug of a new beta-lactamase inhibitor tazobactam and piperacillin at a ratio of 1:4. 1. Serum levels and urinary excretions of TAZ, PIPC and desethyl piperacillin (DEt-PIPC), a metabolite of PIPC, after one shot intravenous administration of 50 mg/kg of TAZ/PIPC to two children (6-7 years old) were investigated. The serum TAZ level at 0.08 hour was 50.8-51.0 micrograms/ml after administration. Then TAZ concentrations gradually decreased with half-lives of 0.38-0.45 hour, and reached 1.0-1.4 micrograms/ml after 2 hours and was not detected after 3 hours and 6 hours. Serum PIPC levels at 0.08 hour was 167.0-231.0 micrograms/ml after administration. Then PIPC concentrations gradually decreased with half-lives of 0.41-0.55 hour, and reached 1.2-2.4 micrograms/ml after 3 hours and was not detected after 6 hours. DEt-PIPC was detected slightly in serum. A ratio of TAZ to PIPC was about 1 to 4 in serum at each time. Urinary recovery rates of TAZ in the first 6 hours after administration of TAZ/PIPC were 33.5-90.1% and those of PIPC were 41.9-77.8% and those of DEt-PIPC were 1.5-2.8%. 2. TAZ/PIPC was administered to 27 pediatric patients (their ages ranged between 2 months and 11 years old) with various infections, and clinical and bacteriological effects and adverse reactions were investigated. Single doses were 26.2-55.6 mg/kg, frequencies of administration were 3-4 times a day, and durations of administration were 3 1/3-7 1/3 days, and total dosages were 4.5-33.75 g. Clinical effects were evaluable in 26 cases. Responses were rated as "good" in acute purulent tonsillitis 1 case and acute purulent otitis media 1 case, as "excellent" in acute sinusitis 1 case, as "excellent" in 2 and "good" in 1 out of 3 cases of acute bronchitis, as "excellent" in 13 and "good" 2 out of 15 cases of acute pneumonia, as "excellent" in acute urinary tract infection 2 cases and as "excellent" in acute enteritis in 1 case, acute appendicitis in 1 case and lymphadentis in 1 case. In all cases, the results were rated as "good" or "excellent". Antimicrobial effects against a total of 10 strains identified or assumed to be pathogenic bacteria were evaluated. The 10 strains of bacteria included 4 strains of Streptococcus pneumoniae, 3 strains of Haemophilus influenzae (2 strains beta-lactamase producing), 2 strains of beta-lactamase producing Moraxella catarrhalis, 1 strain of beta-lactamase producing Morganella morganii. All the bacteria listed here were judged to have been eradicated. Adverse reaction was observed in 1 case with mild diarrhea. As abnormal changes in laboratory data, leucocytopenia in 1 case, elevation of GOT. GPT in 2 cases and eosinophilia in 1 case were observed. On the basis of the findings, TAZ/PIPC was considered to be effective and safe in the treatment of pediatric infections.
