Upcoming changes to the WHODrug Global files

To meet new requirements, such as changes in regulatory expectations and developments in technology, UMC is committed to the corresponding necessary updates in WHODrug Global.

We would like to inform you about three planned modifications related to the WHODrug Global .txt and .csv files.

1. Standardisation of the letter case in the C3 format of WHODrug Global 

Description: Based on user requests, UMC will standardise the letter case of drug names in the C3 format. This modification effectively standardises the appearance of drug names bearing the same drug code (all drug names with the same drug code will have the same case). 

Implemented from release: September 2021 

Points to consider: This modification will not affect any IDs (i.e. the MPID or the drug code), and will not affect users of the B3 format.   

2. Expansion of the substance length field 

Description: To accommodate for more precise naming of substances according to global standards (e.g. ISO IDMP), and thereby demanding more character spaces, the substance name field in WHODrug Global will be extended. In the B3 format (BNA.csv/txt), the substance name field will be extended from 45 to 250 characters. In the C3 format (SUN.csv/txt) the substance name field will be extended from 110 to 250 characters. 

Implemented from release:March 2022 

Points to consider: This will affect both B3 and C3 formats. 

3. Updated country codes and names 

Description:UMC will update country codes and names for a few countries, according to the ISO 3166-1 standard. 

Implementation in release: March 2022 

Points to consider: This mainly affects the C3 format, but can also affect the B3 format, depending on implementation.
