Dear Pash!

❝ One small confusion how to control last point Cmax in Fed BE study of prazole DR tablets. In some subjects Cmax is observed in last time points.


What was your sampling schedule? Did these subjects show low concentrations as well? Did you observe this effect both after test and reference or only after the reference? See this nasty example.

❝ Shall we exclude data of such subjects from final BE calculation?


What do you mean by “shall we”? What does your protocol state? To which regulatory agency will you submit the study?
