» I would like to have the help of the forum participants on a tricky question, ie which IR Cmax should be considered to assess the potential bioequivalence between an IR formulation administered BID and an XR formulation administered OD on day 1 and at steady-state. This is for a submission to FDA.

Not sure if the following will answer your Q exactly and whether it still exists on FDA website (or they blacked out the results):
