A unit of presentation represents a qualitative concept that describes a countable entity in which the clinical drug is presented (e.g. tablet, capsule) or in which it is bounded (vial, ampule).  The 732935002 | Unit of presentation (unit of presentation)|  hierarchy supports harmonization between SNOMED CT's Drug Concept Model and the International Organization for Standardization's Identification of Medicinal Products (IDMP) standards for product strength.

Out of Scope:

  • Concepts representing proprietary dose forms
  • Concepts that contain modifiers, e.g. hard capsule, capsule for inhalation

Unit dose

The Unit dose (qualifier value) is unacceptable for representing unit of presentation.
