Nuedexta, which has had a checkered development history, was discussed on this board more than six years ago (e.g. #msg-3877326). The drug is a fixed-dose combination of two generics: quinidine and dextromethorphan.
I don't own AVNR at all, but have some sentimental ties to AVNR because it was the first biotech I ever owned way back when it was known as Lidak. So, good to see some good news for them. I assume, given that Nuedexta is just a fixed-dose combo of two generics, that you don't see a huge market for this drug.
