The Drug Ontology
An ontology to support comparative effectiveness researchers studying claims data.
An ontology of drugs.
DrOn contains content developed by the National Library of Medicine in RxNorm. In creating DrOn, we have used RxNorm content only with SAB = RXNORM.
When citing DrOn, use the permanent URL of the ontology: http://purl.obolibrary.org/obo/dron.owl. When referencing a specific component of the DrOn, such as a class, object property, annotation property, or individual, use the Uniform Resource Identifier (URI) of that component.
