The EU Reference Dates (EURD) list establishes harmonised EU reference dates and PSUR submission frequencies for active substances and combinations of active substances.
Why a pharmacovigilance professional uses it
The EURD list is an operational planning resource for determining whether a PSUR is required, its reporting frequency and the relevant data lock point. It is updated periodically and should be checked against the current published version rather than copied into static internal schedules without change control.
The official EMA page provides the current list and supporting material for requests to amend or add entries.
