RxNorm and Routed Generics

The concept of a routed generic as the atomic level of a medication in EHRs, PHRs, CPOE and ACPOE systems is popular.  It is becoming a larger issue with Med Rec.  For example, I know I take oral fish oil, but I can never remember the exact strength.  So identification of the drug (and route) is common for people to state.

One of the problems with RxNorm is that there is not explict support for this concept.

• Do we need to ask the NLM for more support for this concept?
  
• Is there an easy SQL fix to this issue in the data structure?
  

Any input is appreciated.
