Bioequivalence and Bioavailability Forum

❝ Dextromethorphan hydrobromide belongs to the class II of biopharmaceutics classification system (BCS), exhibits low solubility and high permeability.

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.
