Bioequivalence and Bioavailability Forum

Dears

I have a solifenacin succinate/tamsulosin HCl bioequivalence study, I will perform a multiple-dose study for tamsulosin modified release for Europe, I'm a little confused about the planned washout for this study as there are no enough public assessment reports for the combination, should I take in account the solifenacin washout period also or to design on tamsulosin only is enough (i.e one-week washout between 2 periods from last dose)

thanks in advance
