The Anatomical Therapeutic Chemical (ATC) classification system groups active medicinal substances by the organ or system on which they act and by therapeutic, pharmacological, and chemical properties. The ATC/DDD methodology is maintained by the WHO Collaborating Centre for Drug Statistics Methodology and endorsed by WHO for drug utilization monitoring and research.

The Anatomical Therapeutic Chemical (ATC) classification system is a reference classification for active medicinal substances. It supports drug utilization research by organizing substances across five levels, from broad anatomical or pharmacological groups to chemical substances.
The WHO Collaborating Centre for Drug Statistics Methodology maintains the ATC/DDD Index and the associated Defined Daily Dose methodology. The current searchable index is hosted at the Norwegian Institute of Public Health’s ATC/DDD site.
