ATC/DDD

International language for drug utilization research

The Anatomical Therapeutic Chemical (ATC) classification system and the Defined Daily Dose (DDD) as a measuring unit have become the gold standard for international drug utilization monitoring and research.

The ATC/DDD system is a tool for exchanging and comparing data on drug use at international, national or local levels.
