Rationalization of Unit of Measure Concepts

Notification of inactivation of duplicate concepts following DEUSG agreement.

Background
A proposal originated from a DEUSG member (UK) and was presented and discussed at DEUSG between July and September 2025. Support was expressed by DEUSG members for rationalization of two overlapping sub-hierarchies:
• 732935002 |Unit of presentation (unit of presentation)|
• 408102007 |Unit dose (qualifier value)|.
The current drug model only uses Unit of presentation to model Clinical Drug concepts.
