Start of review concerning veterinary medicines containing the excipient N-methyl pyrrolidone

EMA has started a review of veterinary medicines containing the excipient N-methyl pyrrolidone (NMP).

These medicines have been used widely throughout the EU for decades. It has been noticed that some of the authorised medicines containing the above-mentioned excipient do not have specific safety warnings in the product information to inform about potential risks to the users and target animals. NMP should be considered as a substance which has the potential to cause developmental toxicity and has been legally classified as ‘Repr. 1B (may damage the unborn child)’ according to the harmonised classification and labelling (ATP09) approved by the European Union.

Having considered this issue, the national veterinary medicines regulatory authority of Germany requested EMA’s veterinary medicines committee (CVMP) to assess its impact on the benefits and risks of veterinary medicinal products containing N-methyl pyrrolidone.

EMA will now review the available data to determine if any action is necessary to protect animal or public health or the environment.
