MHRA has created a new international recognition route for medicines utilising pre-existing approvals from Australia, Canada, the European Union, Japan, Switzerland, Singapore and the United States. This new framework will support patients in the UK with expedited access to safe and effective medicines that have been approved by trusted regulatory partners. From 1 January 2024, international recognition will sit alongside MHRA’s current national procedures.


The MHRA webinar held on 23 November 2023 provided potential applicants with the opportunity to increase their knowledge and understanding of the guidance on the International Recognition Procedure. A follow-up webinar in April 2024 presented post-launch updates and latest information about the new route.
