Hi Pash,

❝ What is the criteria set by EMEA for long half life drugs.

There is none. For IR products the use of truncated AUC₇₂ is not limited to drugs with a long half life. See the GL Section “Sampling times”:

AUC truncated at 72 h (AUC_(0-72h)) may be used as an alternative to AUC_(0-t) for comparison of extent of exposure as the absorption phase has been covered by 72 h for immediate release formulations. A sampling period longer than 72 h is therefore not considered necessary for any immediate release formulation irrespective of the half life of the drug.

❝ […] In few subjects at 72.0 hour concentration is zero.

I hope you mean BLQ?
