Periodic safety update reports

This page includes information on periodic safety update reports (PSURs), European Union (EU) reference dates for medicines and the frequency of submission of PSURs.

PSURs are reports providing an evaluation of the benefit-risk balance of a medicine. Marketing-authorisation holders must submit PSURs at defined time points following a medicine’s authorisation. PSURs summarise data on the benefits and risks of a medicine and includes the results of all studies carried out with this medicine, both in its authorised uses and in unauthorised uses.

The Agency uses the information in PSURs to determine if there are new risks identified for a medicine or whether the balance of benefits and risks of a medicine has changed. It can then decide if further investigations need to be carried out or can take action to protect the public from the risks identified, such as updating the information provided for healthcare professionals and patients.

More information is available in:

Mandatory use of central PSUR repository (updated)

As of 13 June 2016, marketing authorisation holders are required to submit all PSURs in the EU to the central PSUR repository, using the eSubmission Gateway/ Web Client.

Use of the PSUR repository is mandatory for both centrally and nationally authorised medicines, whether they follow the EU single assessment or a purely national assessment procedure. Marketing authorisation holders should no longer submit PSURs to national competent authorities directly.

For more information on the changes to the submission of PSURs and how to use the PSUR repository, see:

Assessment of PSURs

The Agency carries out single assessments of related PSURs for medicines containing the same active substances or combinations of active substances.

Single assessments occur even though the active substances in question may be contained in medicines subject to different marketing authorisations and authorised in more than one Member State. This aims to harmonise and strengthen the safety and benefit-risk review of medicines across the European Economic Area.

The Agency sends the following documents to all marketing-authorisation holders whose medicines are part of a single PSUR assessment:

  • preliminary single assessment report by the Pharmacovigilance Risk Assessment Committee (PRAC) rapporteur;
  • updated single assessment report by the PRAC rapporteur;
  • PRAC recommendation;
  • Committee for Medicinal Products for Human Use (CHMP) opinion (if applicable).

Single assessments of PSURs based on active substances and combinations of active substances for centrally authorised medicines began in July 2012. The Agency expanded this to active substances contained in centrally authorised medicines and in both centrally and nationally authorised medicines in April 2013.

The Agency also carries out the single assessment of active substances contained only in nationally authorised medicines. Information on how to submit these PSURs and to help marketing-authorisation holders prepare for single-assessment procedures is available on Periodic safety update reports: questions and answers.

List of EU reference dates and PSUR submission

The Agency maintains a list of EU reference dates (EURDs) and frequency of submission of PSURs for active substances contained in medicines in the EU:

The EURD list includes the active substances and combinations of active substances contained in medicines subject to different marketing authorisations and authorised in more than one Member State, together with:

  • the corresponding EU reference dates;
  • frequencies for submission of PSURs;
  • related data lock points.

The EU reference date corresponds to the date of the first marketing authorisation of a medicine containing that active substance or that combination of active substances in the EU, or alternatively the earliest of the known dates of the marketing authorisations for a medicine containing that active substance or that combination of active substances.

The PSUR frequency and related data lock points for a given active substance or combination of active substances in the EURD came into effect on 1 April 2013. They overrule the submission schedule described in Article 107c (2) of Directive 2010/84/EU, and any conditions related to the frequency of submission of PSUR included in the marketing authorisation.

The EURD list aims to facilitate the harmonisation of data lock points and frequency of submission of PSURs for medicines containing the same active substances or combinations of active substances. This allows the single assessment of related PSURs to take place.

Marketing authorisation holders are required to submit PSURs according to the dates published in the EURD list. Full details are available in the EURD list cover note:

Amending the EURD list

Marketing-authorisation holders and other stakeholders can request amendments to the EURD list for reasons of public health, to avoid a duplication of the assessment or to achieve international harmonisation. To request an amendment, stakeholders must complete the template below and send the request to eurdlist@ema.europa.eu.

Any changes to the list, following a request for amendment, are approved or denied by the CHMP and the Coordination Group for Mutual Recognition and Decentralised Procedures - Human (CMDh) following consultation with the PRAC.
