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.

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