Colistin combinations

Current status
European Commission final decision

Overview

On 21 April 2016, the European Medicines Agency (the Agency) completed a review of the effectiveness of and antimicrobial resistance to all veterinary medicinal products containing colistin in combination with other antimicrobial substances to be administered orally. The Agency's Committee for Medicinal Products for Veterinary Use (CVMP) concluded that the overall benefit-risk balance for the aforementioned products is negative, due to a lack of clinical relevance and in view of over-exposure of colistin that could pose a potential risk to animal and human health from an acceleration of the occurrence of colistin resistance. The CVMP recommended that all marketing authorisations for veterinary medicinal products containing colistin in combination with other antimicrobial substances to be administered orally should be withdrawn throughout the European Union (EU).
