F. Maggiolo et al., PHARMACODYNAMIC EFFECTS OF SUBINHIBITORY CONCENTRATIONS OF IMIPENEM ON PSEUDOMONAS-AERUGINOSA IN AN IN-VITRO DYNAMIC-MODEL, Antimicrobial agents and chemotherapy, 38(6), 1994, pp. 1416-1418
The postantibiotic effect (PAE), sub-MIC effect (SME), and postantibio
tic sub-MIC effect (PASME) of imipenem on Pseudomonas aeruginosa were
investigated with an in vitro dynamic model reproducing in vivo elimin
ation kinetics of the antibiotic. The PASMEs were constantly longer th
an the corresponding SMEs, but differences between them sere not stati
stically significant. Both PASMEs and SMEs were initially bactericidal
and were significantly longer than PAEs. The mean values of both PASM
Es and SMEs were over 12 h. SMEs appear to be more relevant for the ba
cterial growth kinetics than PAEs.
