In March 2017, the first full B3/C3 format files were made available for download along with the B2/C-format files.
The B2-format will coexist in parallel with the B3/C3 formats until September 2018. Please note that from June 2017 the B2-format is produced in a limited version exclusively updated with new inserts (i.e. new ATC codes and drug names), no records are deleted and modifications on existing records are not included.
The C-format will also be available, upon request, together with the B3/C3 formats until September 2018. Please note that, similarly to the B2-format, the C-format will exist in a limited version which is updated with new inserts only. If you wish to retrieve the C-format data it needs to be requested with three months notice.
In March 2019 the new B3/C3 formats will definitively replace the B2/C formats.
All dictionary types (WHODrug Enhanced; WHODrug Enhanced and WHODrug Herbal; WHODrug Global) will be available in B2/B3/C3 formats as described in figure 1 and with the limitations communicated in the WHODrug Global, transition plan, please refer to this document for details. The only exception is the C-format, which will be available upon request only.
WHODrug SDGs will be exclusively compatible with the B3-format starting from June 1st 2017.
During the complete transition period, 2017-2018, WHODrug Cross Reference ATC 5 will be made available in two datasets, one compatible with the B2 format and one compatible with the B3-format.
Please note that Cross Reference Tool Japan will instead be exclusively compatible with the B3-format starting from June 1st 2017.
