SNOMED International and International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH)/MedDRA Maintenance and Support Services Organization (MSSO), together with regulatory and industry partners, developed the SNOMED CT to MedDRA and MedDRA to SNOMED CT maps as part of the WEB-RADR 2 project, funded by the European Union's (EU) Innovative Medicines Initiative (IMI). For full details, please see the Release Notes.

This will apply to all types of simple and complex Map Reference Sets going forward, including (but not limited to) the SNOMED CT MedDRA Simple Map package, from this 2022 release onwards. Please see section "7.3. RF2 map files" in the Release Notes for full details of the improvements.
