Substance Groupers Based on Structure

Overview

Groupers based on structural properties of the substance that are deemed to be clinically useful will be included in the Substance hierarchy.

For example,

• Benzodiazepine (substance)

• Quinolone (substance)

Modeling

The following illustrates the stated and inferred view.

Use the following pattern for the FSN. Groupers are expressed in the singular, i.e., compound not compounds.

Examples of substances that represent a structural grouper:

• Organic nitrogen compound (substance)

• Halide compound (substance)

• Triazine derivative (substance)

• Copper and/or copper compound (substance)

Where the same word is used to identify both a group of substances with a particular chemical structure and a particular chemical substance, the following terming for the FSN is used for the substance grouper concept.

Substance with X structure (substance)

For example,

• Substance with tetracycline structure (substance)

• Substance with cresol structure (substance)

• Substance with benzene structure (substance)

Use the following pattern for the Preferred Term.

For example,

• Organic nitrogen compound

• Halide compound

• Triazine derivative

• Copper and/or copper compound

Where the same word is used to identify both a group of substances with a particular chemical structure and a particular chemical substance the following pattern will be used for PT the substance grouper concept.

Substance with X structure

For example,

• Substance with tetracycline structure

• Substance with cresol structure

• Substance with benzene structure

Additional synonyms are not allowed unless explicitly identified as an exception in the editorial guidelines.
