title: [Pharmacokinetics and clinical studies of aztreonam in neonates and premature infants].
abstract: Pharmacokinetics and clinical evaluation of aztreonam (AZT) in the neonates and premature infants were studied with the following results: 1. Serum concentrations of AZT in 60 minutes intravenous drip infusion of AZT 20 mg/kg to 6 cases of neonates with 2 to 22 days of age were 45.5 +/- 0.87 micrograms/ml immediately after the completion of intravenous drip infusion, 37.8 +/- 1.62 micrograms/ml 1 hour after, 31.2 +/- 1.92 micrograms/ml 2 hours after and 19.7 +/- 2.36 micrograms/ml 4 hours after, respectively. Serum half-life was 3.61 +/- 0.53 hours on the average. 2. Urinary excretion rate 6 hours after intravenous drip infusion was 26.4 +/- 6.86% on the average. 3. Clinical evaluation was given to 1 sepsis case of 7-days of age and it was effective. There was no abnormal clinical or laboratory finding considered to be associated with AZT.
