Thanks JTFM. This looks like one of the 505b products they have talked about. It is interesting that they chose to brand this. If you look at the orange book for these two items, you see that they are both Reference Listed Drugs (RLD) and the 300mg version is listed as a reference standard (RS). Only the branded product from Concordia has these same designations. I don't get how a late entrant from a 505b process attains these designations, but I think it means we are now a branded version of this and can probably charge more for it.
It has been on the drug shortage list as well due to high demand. With Covid supposedly on the rise again, maybe this can be a winner. As you point out, today's AH volume may be the proof of this.
