Department of Pediatrics, Second Tokyo National Hospital.

A pharmacokinetic study on ceftriaxone (CTRX) was conducted and the results obtained are summarized as follows. 1. CTRX was given in a dose of 20 micrograms/kg by intravenous bolus injection to 13 neonates, and satisfactory blood concentrations of the drug were achieved. However, since even a once daily administration revealed trough values of 10-20 micrograms/ml, CTRX may accumulate if administered to neonates of low weight. 2. The rate of CTRX transfer to cerebrospinal fluid was 5.7% in a neonate given a dose of 20 mg/kg by intravenous bolus injection. 3. The urinary recovery rate was 8.4% up to 12 hours in a neonate given a dose of 20 mg/kg by intravenous bolus injection.
