Based on evaluation of the currently available data and the Rapporteurs’ assessment reports, the CHMP concluded that for oral formulations of norfloxacin containing medicinal products the benefit does not outweigh the risk in acute or chronic complicated pyelonephritis, and therefore adopted an opinion on 24 July 2008 recommending the variation of the Marketing Authorisations by removing the therapeutic indication “ acute and chronic complicated pyelonephritis” from the Product Information for the norfloxacin containing medicinal products taken orally.
