MHRA GMP and GDP are the good manufacturing and good distribution practice the Medicines and Healthcare products Regulatory Agency enforces under the Human Medicines Regulations 2012. The MHRA grants manufacturer's and wholesale dealer's licences on condition the holder complies, inspects the sites that hold them and publishes the rules and guidance as the Orange Guide.
The Orange Guide gathers the UK legislation, the GMP and GDP guidelines and the MHRA's guidance for licence holders. The current print edition, the eleventh, came out in 2022, and an online version is updated between editions. The GMP guidelines are the EU guide's chapters and annexes as they stood when the Brexit transition period ended, and the MHRA's GxP data integrity guidance of March 2018 applies beside them. No certification body certifies against any of it.
