 ===== Drug Domain =====
-The drug exposure domain concepts capture records about the utilization of a Drug when ingested or otherwise introduced into the body. A Drug is a biochemical substance formulated in such a way that when administered to a Person it will exert a certain physiological or biochemical effect. The following products are **not** considered Drugs, but Devices:

-  * Radiopharmaceuticals
-  * Contrast material for imaging
-  * Nutritional products and supplements, including baby formula. In reality that results in the slightly arbitrary and in some cases difficult to ascertain situation that solutions of salts for parental use are Drugs (hydrating patients and maintaining ionic balance), while the addition of nutrients such as glucose or vitamins makes them devices (feeding patients).
-  * Products directly derived from blood (e.g. erythocytes or plasma)
-Drug domain Concepts should be used in the drug_concept_id of the DRUG_EXPOSURE the DRUG_ERA and the DOSE_ERA (both only at the Ingredient level) tables, or in the value_as_concept_id field of the OBSERVATION or MEASUREMENT table (e.g. for observations like "Plasma level").
-==== Overall Structure ====
-{{ :documentation:vocabulary:drugdomain.jpg?nolink |}}
-Structure of Drug Domain
-Standard Concepts are taken from the [[documentation:vocabulary:rxnorm|RxNorm]] and [[documentation:vocabulary:rxnorm_extension|RxNorm Extension]] vocabularies. All Standard RxNorm and RxNorm Extension Concepts can be used in the drug_concept_id fields.
-RxNorm is the foundation for the combined Domain space. All valid RxNorm Concepts (invalid_reason is null) are used as Standard Concepts. However, RxNorm only contains Drug Concepts for products sold in the United States. All Concepts derived from international products are availabe in the RxNorm Extension vocabulary. Apart from the different vocabulary_id, both RxNorm and RxNorm Extension for a common Drug Universe with identical rules for relationships and Concept Ancestry.
-RxNorm and RxNorm Extension Concepts are hierarchical. Therefore the Concepts can also be used as Class Concepts: descendants of any Standard Concept in the CONCEPT_ANCESTOR table can expected to be a correct semantic match in a query. For example, a query for the descendants of an ingredient should turn up all drug products (Clinical Drug or Branded Drug) containing that ingredient.
-On top of this combined RxNorm/RxNorm Extension Drug Domain are drug classification systems. These are derived from a variety of different vocabularies. **Note:** Any classification Concept may exist in different classifications, and therefore cannot be considered as unique. For example, NSAID Analgesics exist with very similar memberships as ETC, VA Class and SNOMED classes.
-==== Concept Classes ====
-The Concept Classes for the drugs in the Drug Domain are based on RxNorm, and those for the Drug Classification based on that of the source vocabulary:

-==== Relationships ====
-All Source Vocabularies are mapped to the RxNorm Standard Concepts, and Multilex and DMD also to the DMD Standard Concepts. The mapping is either constructed from the vocabulary source and in some cases curated by the vocabulary team.
-=== NDC, GPI, Multum and Genseqno to RxNorm mapping ===
-All these are provided by RxNorm.
-=== CVX, OXMIS, Read and CPT4 to RxNorm mapping ===
-These are manually curated by the vocabulary team
-=== MeSH to RxNorm mapping ===
-This is provided by the UMLS.
-=== CIEL, VA Product, Gemscript and HCPCS to RxNorm mapping ===
-These are inferred from public source and curated by the vocabulary team.
-=== DMD, Gemscript and Multilex to RxNorm/DMD mapping ===
-These are inferred from public source and curated by the vocabulary team.
-=== Internal relationships ===
-All relationships provided by RxNorm are loaded as is, but renamed to follow the relationship_id formatting rules and allow for bi-directional mappings, see [[documentation:vocabulary:rxnorm|RxNorm]]. All internal relationships of DMD are derived from the source and converted to generate "pseudo"-RxNorm relationship, omitting the Drug Form and Drug Component Concepts. See [[documentation:vocabulary:dmd|DMD]] for details. All hierarchical relationships of the drug classes are loaded for the source as is and used to form the CONCEPT_ANCESTOR table.
