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 a Clinical drug concept.
