Healthbase Australia has updated the online Australian Medicines Terminology browser to include the 2.23 version of the AMT released by NEHTA yesterday.
All deprecated versions are still available for browsing/searching.
Once again, it is a pity the download process cannot be automated. Perhaps if this were the 1980s NEHTA could publish the updates (with sensible filenames!) via an FTP service. I guess we have a lot of catching up to do! Maybe we will just wait a couple of more years until a Web service is established?
