You have probably noticed that the MHRA have moved their web site from their dedicated site (www.mhra.gov.uk) to be part of the UK government’s main site (www.gov.uk). The MHRA’s new home page can be found at the following address.
However, it is still possible to see archived versions of the old web site (snapshots in time) dating from 2003 to January 2015 on the UK’s National Archives. Furthermore, there are archived versions of the predecessor site, for the Medicines Control Agency (MCA), dating back as far as 2002. Links to these archives are provided below.
