Dear Helmut,

Thanks for the reply. In such a precarious situation my only hope to defend the ANDA would be based on the following assumptions.

The guidance recommendations are nonbinding
The demonstration of bioequivalence to an active metabolite is more “closer” to the actual clinical situation than demonstration of bioequivalence to an inactive metabolite.

Can any one let know why for Prasugrel, bioequivalence is based on inactive metabolite and active metabolite PK is submitted as supportive data. The condition that data on active metabolite is required implies that it can be quantified. Enlighten me if I am missing some thing over here.
