The Anatomical Classification of Pharmaceutical Products has been developed and maintained by the European Pharmaceutical Market Research Association (EphMRA) and is therefore the intellectual property of this Association.

EphMRA's Classification Committee prepares the Guidelines for this classification system and manages new entries, changes and improvements in consultation with pharmaceutical companies. The contents of the Anatomical Classification of Pharmaceutical Products remain the copyright to EphMRA. Permission for use need not be sought and no fee is required. We would appreciate, however, the acknowledgement of EphMRA Copyright in publications etc.

Users of this classification system should keep in mind that Pharmaceutical markets can be segmented according to numerous criteria.
