[Clinical evaluation of cefpiramide in pediatrics].
A clinical study was made of cefpiramide (CPM) a new cephem-type antibiotic for injection and the following results were obtained. Blood level of CPM, after 20 mg/kg administration by drip infusion over a period of 1 hour, reached its peak of 86 micrograms/ml at the end of the infusion and declined to 19.8 micrograms/ml at 4th hour after infusion with the half-life value of 3.02 hours. Its urinary recovery rate up to 9 hours was 29.2% and the urine concentration from 0 to the 3rd hour was 820 micrograms/ml and from the 3rd to the 5th hour 650 micrograms/ml. In another case of the same dose with intravenous administration, the blood level at the end of the first 1 hour reached 56 micrograms/ml and by the 4th hour it had fallen to 20.6 micrograms/ml and by the 6th hour to 13.6 micrograms/ml. The half-life value was estimated as 2.44 hours. CPM was administered in 2 or 3 divided doses at a daily dosage ranging from 41.7 to 62.5 mg/kg by intravenous injection or by 1-hour drip infusion to 6 patients (3 cases of pneumonia, 2 cases of urinary tract infections, 1 case of purulent cervical lymphadenitis) and the following clinical results were obtained; "markedly effective" 3 cases, "effective" 2 cases, and "ineffective" 1 case. The overall efficacy rate was 83.3%. No side-effects or abnormal laboratory findings were found in any of the 7 patients including 1 patient who was excluded from the efficacy evaluation because of Kawasaki's disease.(ABSTRACT TRUNCATED AT 250 WORDS)
