Naming

FSN

Use the following pattern for the FSN where X is the release characteristic, adding a hyphen when appropriate Combined release-characteristic concepts may be created to support modeling of concepts that display multiple release characteristics in a single formulation.

  • X (release characteristic)

For example,

      • Conventional release (release characteristic)
      • Delayed-release (release characteristic)
      • Prolonged-release (release characteristic)*
      • Modified-release (release characteristic)**
      • Delayed-release and prolonged-release (release characteristic)

*Prolonged was selected rather than Extended because feedback was received that it is more clear to translate for non-English speaking users; existing national drug extensions appear to use one or the other of these terms.

**Modified-release is a grouper that is not allowed to be used to model an international clinical drug concept.

Preferred Term

Use the following pattern for the PT where X is the release characteristic, adding a hyphen when appropriate:

  • X

For example,

      • Conventional release
      • Delayed-release
      • Prolonged-release
      • Modified-release
      • Delayed-release and prolonged-release
