The second direction of generic formulation is Moiety combination, route, abstract form, no strength (MisRF) which flows up to Moiety combination, route, no form no strength (MisRf) which flows up to Moiety combination (Misrf).
The third direction of generic formulation is Moiety combination, strength, no form no route (MiSrf, RxN:SCD) which flows up to Moiety combination, form no route no strength (MisrF, RxN:SCDF), which flows up to Moiety combination, route, no form no strength (MisRf), which flows up to Moiety combination (Misrf).
