Page History

The SNOMED CT Medicinal Product hierarchy provides concepts to represent medicinal products at various levels of abstraction with international applicability and support for interoperability in patient care and health data analysis. It provides a foundation from which member nations can extend with additional concepts suitable for their own healthcare culture and practice, or to which existing terminology can be mapped.

This document provides a specification of the SNOMED CT Medicinal Product hierarchy's data model in the international edition of SNOMED CT. This document also provides a description of how aspects of the SNOMED medicinal product hierarchy correspond with the suite of standards in ISO, collectively known as the "Identification of Medicinal Products" (IDMP) standards.

For information on editorial and terming guidance for this hierarchy, please refer to the SNOMED CT Editorial Guide - Medicinal Product. For information on creating a drug extension, please refer to the SNOMED CT national drug extension model specification.
