Groupers Based on Multiple Dispositions, Structures
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.
Overview
Groupers comprised of two or more existing disposition and/or structure groupers that can be sufficiently defined may be included in the |Medicinal product| hierarchy. High-level grouper concepts support the organization of the combined groupers based on disposition and/or structure:
766779001 |Medicinal product categorized by disposition (product)|
763760008 |Medicinal product categorized by structure (product)|
For some medicinal products, their clinical usefulness is related to the combination of both their structure and their disposition; it is the structure that produces the disposition.
For example,
Clemastine is a substance whose anti-histamine behavior is based upon its structure being ethanolamine derived.
Since structure-based grouping and disposition are characteristics of the active ingredient substance(s) present in the medicinal product, combined 'structure and disposition grouping' concepts are inferred by the classifier to medicinal products and include all their child concepts (medicinal product form and clinical drug concepts), although in a browser, the inferred grouping concepts are shown on the proximal concept only (the "medicinal product containing" concept).

Naming
FSN
Use the following pattern for the FSN if the combined grouper is comprised of two dispositions or two structural groupers; align naming and case significance with the PT as described in Groupers Based on Structure and Disposition, respectively. The active ingredients must be in alphabetical order and separated by the word “and”.
Product containing <Active ingredient PT> and <Active ingredient PT> (product)
For example,
Product containing norepinephrine reuptake inhibitor and serotonin reuptake inhibitor (product)
Use the following pattern for the FSN if the combined grouper is comprised of one disposition and one structural grouper; align naming and case significance with the FSN for the concept with the FSN as described in Groupers Based on Structure and Disposition, respectively.
Product containing <Structural grouper active ingredient PT> and <Disposition grouper active ingredient PT> (product)
For example,
Product containing piperazine derivative and histamine receptor antagonist (product)
Preferred Term
Use the following pattern for the FSN if the combined grouper is comprised of two dispositions or two structural groupers; align naming and case significance with the PT as described in Groupers Based on Structure and Disposition, respectively. The active ingredients must be in alphabetical order and separated by the word “and”.
Product containing <Active ingredient PT> and <Active ingredient PT> (product)
For example,
Product containing norepinephrine reuptake inhibitor and serotonin reuptake inhibitor (product)
Use the following pattern for the FSN if the combined grouper is comprised of one disposition and one structural grouper; align naming and case significance with the FSN for the concept with the FSN as described in Groupers Based on Structure and Disposition, respectively.
Product containing <Structural grouper active ingredient PT> and <Disposition grouper active ingredient PT> (product)
For example,
Product containing piperazine derivative and histamine receptor antagonist (product)
