“…Enrofloxacin and pefloxacin are Ndealkylated to form ciprofloxacin and norfloxacin, respectively, similarly like fleroxacin (Lode et al, 1987;Küng et al, 1993). Other prominent metabolic pathways include oxidation to oxo-metabolites at the piperazine ring (Nix and Schentag, 1988), the major metabolites of ciprofloxacin, enoxacin, and norfloxacin (Lode et al, 1990;Anadón et al, 1995). Quite often, glucuronidation occurs, primarily on the carboxylic acid at position 3.…”
