title: [Pharmacokinetics of azlocillin, a new semisynthetic, wide-spectrum antibiotic (author's transl)].
abstract: Azlocillin, a new semisynthetic penicillin with a wide spectrum of antimicrobial activity and a member of the ureidopenicillin group, was administered to ten adults in a dosage of 2 g by intravenous bolus injection. The determination of antibiotic activity in serum and urine demonstrated an average concentration of 58.9 mug/ml after one hour, 28.1 mug/ml after two hours and 6.1 mug/ml after four hours. The total urinary excretion was 60% within six hours. The pharmacokinetic parameters were calculated for the one and two compartment models, respectively. Mathematical analysis according to an open two-compartment model resulted in better curve adjustment as judged from the sum of the deviant squares. The resulting parameters for volume of distribution and rate of elimination show only minor differences however. Similar results were seen on comparison with the respective data for ampicillin.
