Sodium valproate and Valproic acid
This Editorial Guide is used for Education Purposes Only. It is used in the Authoring Courses and Certifications. It is based on the January 2026 Editorial Guide.
The Count of active ingredient (attribute) relationship has been added to certain single-ingredient valproic acid or sodium valproate clinical drug concepts to prevent incorrect subsumption under multiple-ingredient concepts (such as those containing both sodium valproate and valproic acid). This modeling ensures correct classification, particularly when substances share a base moiety but differ at the modification level.
For example
765633006 |Product containing precisely sodium valproate 200 milligram/1 each prolonged-release oral tablet (clinical drug)| includes a |Count of active ingredient (attribute)| to prevent it from being inferred as a parent of 1204385002 |Product containing precisely sodium valproate 200 milligram and valproic acid 87 milligram/1 each prolonged-release oral tablet (clinical drug)|.
In addition, when any concept in a sibling set requires the additional |Count of active ingredient| attribute to classify correctly, this attribute should also be added to all sibling concepts for consistency.
