The centralised procedure is a process for obtaining marketing authorisation for a medicine in the EU. The European Medicines Agency (EMA) oversees the centralised authorisation procedure for human and veterinary medicines. This procedure results in a single marketing authorisation, granted by the European Commission, which allows a medicine to be marketed in all EEA (European Economic Area) countries (EU member states and the three EEA EFTA States: Iceland, Liechtenstein, and Norway).
