Abstract
PC-904 was administered to 16 pediatric patients and the following basic and clinical results were obtained.
(1) PC-904 was administered 20-30mg/kg. The serum peak level of PC-904 after drip intravenous infusion over 1 hour was 66.7μg/ml at 1 hour and T1/2 of PC-904 was 67.8 minutes. PC-904 was administered 25-30mg/kg intravenous one shot injection was 49.4-Eg/ml at 1 hour and Ti of PC-904 was 52.2 minutes.
(2) Urinary excretion rate was about 20% up to 6 hours after drip intravenous infusion of 20 mg/kg. In a case of intravenous one shot injection of 25-30 mg/kg, the excretion rate was 11.9-19.9%.
(3) PC-904 was administered 60-120 mg/kg/day for 3-48 days to 5 cases of sepsis and baterial endocarditis, 6 of pneumonia, 2 of sss syndrome (staphylococcal scald skin syndrome) and 3 of pyelonephritis. Clinical effects were excellent in 11 cases and good in 5 cases, effective ratio being 100%.
