Meropenem is a carbapenem antibacterial agent[1]. The MICs of meropenem was 0.03 mg/L against S. aureus and E. coli but > 256 mg/L against C. albicans[2]. It is stable to hydrolysis by most beta-lactamases produced by Gram-negative and Gram-positive bacteria, including penicillinases and cephalosporinases[1].

Meropenem, a carbapenem antibacterial agent, is stable to hydrolysis by most beta-lactamases produced by Gram-negative and Gram-positive bacteria, including penicillinases and cephalosporinases[1]. The MICs of meropenem was 0.03 mg/L against S. aureus and E. coli but > 256 mg/L against C. albicans[2].

In vitro, meropenem has the minimum inhibitory concentration (MIC) values is 128 µg/mL, but meropenem combined with vaborbactam reduced the minimum inhibitory concentration (MIC) values of meropenem by ≥ 64-fold against engineered strains and clinical isolates producing class A serine carbapenemases (e.g. KPC-2, KPC-3, SME-2, NMC-A)[3][4]. The minimum inhibitory concentrations of carvacrol and meropenem on carbapenem-resistant K. pneumoniae (CRKP) strains were detected within a range of 32-128 µg/mL using the broth microdilution method[5]. The MIC90 of meropenem (when tested with a fixed concentration of 8 µg/ml of vaborbactam) for isolates of KPC-positive Enterobacteriaceae was 1 µg/ml, and MIC values ranged from ≤0.03 to >32 µg/ml[6].

In vivo, in fully PTZ (pentylenetetrazol)-kindled mice, intravenous administration of meropenem (500 mg/kg) did not elicit any convulsions in the electroconvulsive shock test with low-intensity stimulus currents[7]. In vivo efficacy test shown that cats were administrated 10 mg/kg q12h meropenem is effected against bacteria with MIC values of 6 µg/ml, 7 µg/ml and 10 µg/ml for IV, IM and SC administration, respectively[8].
