The following final anatomical therapeutic chemical (ATC) classifications and defined daily doses (DDDs) were agreed at a meeting of the WHO International Working Group for Drug Statistics Methodology which took place in October 2000 in the Hague. They came into force on 1 March 2001 and can be viewed on http://www.whocc.nmd.no. The inclusion of a substance in the lists does not imply any recommendation of use in medicine or pharmacy.
