Anaerobic bacteria are a common cause of serious infections. Anaerobic species which predominate in clinical infections include the Bacteroides fragilis group, Clostridium spp. and Peptostreptococcus spp. The oxazolidinones are a novel class of synthetic antimicrobials inhibiting the initiation of protein synthesis. Two compounds of this class, eperezolid and linezolid have been shown to inhibit Enterococcus faecalis and Enterococcus faecium.
In vitro: Ninety per cent of all tested Propionibacterium acnes (30 strains), PeptostreptococccuJ spp. (50 strains), C. perjringens (50 strains) and C. dficile (50 strains) were inhibited by
In vivo: The in vivo effectiveness of eperezolid and linezolid against one strain each of Enterococcus faecalis and vancomycin-resistant Enterococcus faecium was examined in a rat intraabdominal abscess model. Eperezolid was ineffective at doses of 25 mg/kg of body weight twice daily for the reductions in abscess bacterial density for E. faecalis. Against E. faecium infections, intravenous eperezolid was effective, reducing densities approximately 2 log10 CFU/g [2].
Clinical trials: Oral administration of eperezolid (1 000 mg PO) to healthy volunteers has earlier been reported to yield peak serum concentration of 6.28 mg/L, respectively, while the trough concentration was estimated to be 1.62 mg/L, respectively [3].
