[Patterns of clometacillin circulation in the body of laboratory animals].

Distribution of clometacillin in mice, rats and rabbits was studied in comparison with some other penicillins. It was found that clometacillin was superior to all other penicillins used for comparison with respect to the circulation time in the blood after intravenous, intramusclar or intrastomach administration. As for the capacity for penetrating into the tissues from the blood, clometacillin was not inferior to ampicillin and benzylpenicillin and was superior to propicillin, though it was bound by the blood serum proteins to a greater extent than the other penicillins used for comparison.
