Ecotoxicological Screening of the Select Drug II

Charles University in Prague, Faculty of Pharmacy in Hradec Králové, Department of Pharmaceutical Botany and Ecology Quinolone antibacterial agents represent a chemically homogenous group of purely synthetic antibiotics which originated in the early 1960s and still play an important role in the antimicrobial chemotherapy. Quinolones (or more specific, fluoroquinolones) are frequently used in human therapy for treatment of both common and serious diseases (they are irreplaceable also against bioterrorist weapons, such as anthrax). Some of the fluoroquinolones are also among the most used veterinary antimicrobials, including their large-scale usage in aquaculture. Only in the Czech Republic, their annual consumption is in the order of millions of defined daily doses (DDD). Fluoroquinolones as entirely synthetic compounds do not have any natural source in the environment - therefore their occurrence in both terrestrial and aquatic ecosystems is the result of human activity. Excluding the direct application to the aquatic environment (prophylaxis and treatment of bacterial diseases in the aquaculture), the most common point of entry of fluoroquinolones into the environment is via the wastewaters.
