This page defines the modelling rules and description templates for Phase 1 only of the Canadian Medicines Terminology (CMT) project. Phase-specific content will be added as the project progresses.
Definition
An abstract representation of a medicinal product based on a description of its precise active ingredients (PAI) only and explicitly, the stated basis of strength substance with strength, and dose form. The precise active ingredients used to define the VCD do not include hydration, unless this is part of the basis of strength substance.
Attributes and Concepts
The VCD uses the following defining attributes:
Attribute | Alias | Group | Card | G Card | D/O | Range |
373873005 |Count of base of active ingredient| | BCount | NO | 1..1 | 0..0 | DATA | Integer >#0.. |

732943007 |Has basis of strength substance| | BOSS | YES (1,2) | 0..* | 0..1 | OBJECT | < 105590001 |Substance| |

Descriptions
VCD generation of en-CA Fully Specified Name (FSN)
Format
“Product containing precisely ” [[ + @BOSS]] [“ (as ” [[ + @PAI]] “)”]1“ ” [[ + @PSNV]] “ ” [[ + @PSNU]]“/1 each ” [[ + @MDF]] “ (clinical drug)” 2
VCD generation of en-CA Preferred Term (PT)
Format
[[ + @BOSS]] “(“[[ + @PAI]] “)”1) “ ” [[ + @PSNV]] “ ” [[ + @PSNU]] “ ” [[ + @MDF]]3
Rules for English descriptions
1: PAI is used here when BOSS <> PAI
2: For all attribute values, use the en-CA FSN with no semantic tag
3: For all attribute values, use the en-CA PT
VCD generation of fr-CA Fully Specified Name (FSN)
Format
“produit contenant précisément ” [[ + @BOSS]] [“ (” [[ + @PAI]] “)”]1“ ” [[ + @PSNV]] “ ” [[ + @PSNU]]“/1 chaque ” [[ + @MDF]] “ (médicament clinique)” 2
VCD generation of fr-CA Preferred Term (PT)
Format
[[ + @BOSS]] (“ “(“[[ + @PAI]] “ ” [[ + @PSNV]] “ ” [[ + @PSNU]] “ ” [[ + @MDF]]3
Rules for French descriptions
1: PAI is used here when BOSS <> PAI
2: For all attribute values, use the fr-CA FSN with no semantic tag
3: For all attribute values, use the fr-CA PT
