title: [Fundamental and clinical studies of cefixime in children].
abstract: Cefixime (CFIX), a new oral cephalosporin, was administered clinically at a daily dose of 3.4 mg/kg to 10.4 mg/kg to each of 12 children, aged from 2 months to 14 years old. An additional separate study was done to compare the serum and urinary levels of CFIX in 3 children when each was administered with 100 mg of the drug in capsule with the serum and urinary levels of the drug in the same children when each was given the same amount of drug in the form of 5% granules. The results of these trials are summarized below. Peak serum levels of CFIX administered in capsules and 5% granules averaged 1.4 micrograms/ml and 1.9 micrograms/ml, respectively. The half-life of the former was 5.13 hours, while that of the latter was 4.17 hours. The difference in the peak levels was statistically insignificant. The urinary excretion of CFIX in either form of the drug (capsules and granules) was about 14-18% in 12 hours. In 9 cases of respiratory infections, therapeutic results were excellent in 3 cases, good in 6 cases, and the effective rate was 100%. In 2 cases of urinary tract infection, results were excellent in 1 case and good in 1 case. The drug efficacy was poor in 1 case of purulent cervical lymphadenitis, probably caused by Staphylococcus aureus. No adverse reactions attributable to the drug were observed. CFIX may be expected to be a highly effective and safe agent in moderate respiratory and urinary tract infections of children.
