Hi Helmut,

❝ If you get a CI within 80–125% after 10 mg compare to 8 mg without dose-correction f is lower, right? It might be possible that (e.g. with an MR compared to an IR) you partly miss the absorption window of the drug. f will be lower.

You're right - I meant if f and clearance are different than it wouldn't be appropriate to dose normalize. In a properly designed study, it would seem unlikely clearance would be much different though since the strengths are similar.
Thanks for your input!
