Thanks
I read papers where it has classified as Class II, but also I found several publications that describe Dextromehorphan HBr as very high soluble substance.

I was wondering if I could ask for a biowaiver, during the evaluation of an oral product containig dexthrometorphan.

I gone through reviews, I found Dextromehorphan Practically insoluble in water.

The Waiver request of in-vivo testing: 30 mg/600 mg based on acceptable bioequivalence studies on the 60 mg/1200 strength, acceptable dissolution testing across all strengths.
