Upgrading from WHODrug Enhanced to WHODrug Global

Goodbye, WHODrug Enhanced. From now on, WHODrug Global is the only dictionary available to our users.

So long, WHODrug Enhanced

WHODrug Enhanced was introduced in 2005 and mainly provided WHODrug users with information on non-herbal medications. The dictionary has now been discontinued and replaced by WHODrug Global. Older versions of WHODrug Enhanced will still be available to users, with the last release being 1 September 2020.

WHODrug Global – what is it?

Today, all organisations with a valid WHODrug licence have access to WHODrug Global data.

WHODrug Global is a comprehensive and standardised drug dictionary. It contains all of the information found in WHODrug Enhanced and additionally covers herbal medications. WHODrug Global was officially launched on 1 March 2017 and is now the only WHODrug dictionary available to all WHODrug users, harmonising data collection and and simplifying regulatory submissions.

What is the difference between the two dictionaries?

Why WHODrug Global?

In October 2017, the U.S. Food and Drug Administration (FDA) published a notice in the Federal Register in which they stated that the use of the B3 format of WHODrug Global is required in submissions for studies starting after 15 March 2019. Furthermore, the U.S. FDA Data Standards Catalog has been updated with this information.

With the increased focus and recommendations of authorities to use WHODrug Global for coding of concomitant medications, UMC has decided to standardise and streamline its products and releases. By making all WHODrug data available in one dictionary and by releasing this dictionary twice a year, in March and September, we can simplify the use of WHODrug data for users and regulators.
