Description

Ertapenem sodium (L-749345), a long-acting Carbapenem, is a β-lactam antibiotic with a broad antibacterial spectrum. Ertapenem sodium is active against both Gram-positive and Gram-negative bacteria, including Enterobacteriaceae, Streptococcus pneumoniae and most species of anaerobic bacteria[1][2].

In Vitro

Ertapenem sodium inhibits Streptococcus pneumoniae with MIC50s values < 1mg/L[2].
Ertapenem sodium exhibits a bactericidal mode of action as shown by time-killing curves and exhibits a short postantibiotic effect (PAE) of 1.4-2.6 h against the Gram-positive strains but no PAE against Gram-negative strains[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Ertapenem sodium (50 mg/kg; s.c.; q6h; for 24 hours) shows substantial bactericidal activity against S. pneumoniae in the murine thigh infection model[3].
Ertapenem sodium exhibits an AUC0-24 of 586 mg•h/L, Cmax of 140 mg/L following subcutaneous injection (mice 50 mg/kg)[3].
