The 1,000th study has recently been uploaded in the European Union electronic Register of Post-Authorisation Studies (EU PAS Register). A filter is present to search for elderly (65-74 and over 75 years). The EU PAS Register provides a wealth of information on the safety and effectiveness of authorised medicines. It is an openly accessible platform with information on post-authorisation research in medicines already marketed in Europe, and includes study protocols, study results, related publications and other relevant information.
