[Glycopeptide antibiotics: eremomycin, vancomycin, and teicoplanin. Comparison of several parameters of pharmacokinetics and antimicrobial activity].

Pharmacokinetic parameters of eremomycin (Institute of New Antibiotics, the USSR Academy of Medical Sciences), teichoplanin (Lepetit) and vancomycin (Eli Lilly) were compared after their intravenous administration to rats in the same dose of 50 mg/kg. It was shown that the area under the concentration time curve of eremomycin was 2 times smaller than that of teichoplanin and 6 times larger than that of vancomycin. The mean retention time of eremomycin was close to that of teichoplanin and 1.6 times higher than that of vancomycin. Bioavailability of eremomycin and teichoplanin after their extravascular administration was the same and amounted to 94 per cent. Antibacterial activity of eremomycin against methicillin resistant strains of staphylococci was 4 times higher than that of teichoplanin and vancomycin.
