Hello All,

A case of Steady state bioequivalence study in which dose is administered twice daily from Day XX to Day XX. Suppose Day 01 to Day 07 where on day 07 only morning dose will be administered. My question is what is the ideal pre-dose time points required to collect to get Cpd. As per guideline, at least 3 pre-dose samples are required to collect. But as we are administrating Drug twice daily, its is necessary to collect pre-dose for morning and evening both for few days i.e Day 01 (morning evening), Day 04 (morning evening) and Day 07 (Morning)?

Also suggest for t.i.d. administration.

Appreciate your valuable suggestion in this regards.

All we know about the world teaches us that the effects of A and B
are always different—in some decimal place—for any A and B.
Thus asking “are the effects different?” is foolish.    John W. Tukey
