Summary
Serum bactericidal activity (SBA) was studiedin vitro after intravenous administration of cefoperazone alone or in combination with mezlocillin or amikacin to human volunteers. One hour after the infusion, cefoperazone (2 g), cefoperazone + mezlocillin (5 g) and cefoperazone + amikacin (500 mg) achieved comparable activity againstEscherichia coli andKlebsiella pneumoniae (100% of the strains being killed by a 1:8 or greater dilution). The activity of the three regimens was also similar againstPseudomonas aeruginosa (87–96% of the sera had an SBA ≥ 1:8) and somewhat less forStaphylococcus aureus (52–60% with SBA ≥ 1:8). Six and ten hours after administration, the SBAs were much lower for all regimens; a small advantage for cefoperazone + mezlocillin againstK. pneumoniae could be shown in comparison to the other regimens.
Zusammenfassung
Die bakterizide Aktivität im Serum (SBA) wurde nach intravenöser Gabe von Cefoperazon allein oder in Kombination mit Mezlocillin oder Amikacin an freiwillige Probandenin vitro bestimmt. Eine Stunde nach der Infusion erreichten Cefoperazon (2 g), Cefoperazon + Mezlocillin (5 g) und Cefoperazon + Amikacin (500 mg) eine vergleichbare Aktivität gegenEscherichia coli undKlebsiella pneumoniae (bei einer Verdünnung von 1:8 oder darüber wurden 100% der Stämme abgetötet). Die Aktivität der drei Schemata war gegenPseudomonas aeruginosa vergleichbar (87–96% der Seren hatten eine SBA ≥ 1:8), fürStaphylococcus aureus etwas geringer (52–60% hatten eine SBA ≥ 1:8). Sechs und zehn Stunden nach Applikation waren die SBA-Werte für alle Dosierungen erheblich geringer; für die Kombination Cefoperazon + Mezlocillin konnte gegenK. pneumoniae eine gegenüber den anderen Therapieschemata geringfügige Überlegenheit festgestellt werden.
