Dear Helmut,

How about this bioequivalence requirement [based on USFDA individual product bioequivalence recommendations] for Prasugrel Hydrochloride

Active ingredient: Prasugrel Hydrochloride

Analytes to measure (in appropriate biological fluid): Inactive metabolite R-95913 and active metabolite R-138727 in plasma.

Bioequivalence based on (90% CI): Inactive metabolite R-95913.

Please submit the data of active metabolite (R-138727) including individual and mean concentrations, individual and mean pharmacokinetic parameters, and geometric means and ratios of means for AUC and Cmax, as supportive evidence of comparable therapeutic outcome.

Can I justify my ANDA if test formulation is bioequivalent for the active metabolite (R-138727) and not bioequivalent for the Inactive metabolite R-95913?
