Dear Forum Members,

We are planning a multiple dose crossover Bioequivalence study of Nasal Spray, wherein TID dose (08:00, 16:00 and 24:00 hrs) will be given for 4 days i.e. on 4th day after 08:00 hrs, profiling for PK will be done and pre-dose sample will be collected prior to the first dose of the study (1st dose of the study.

Now my query is that do we need to take blood samples till 5 half life of the drug and pre-dose sample also require to be taken prior to 4th day dosing? If we following parameters to be considered for BE
Parameters to be calculated:
Cmax
AUCtau
Tmax
Kel
and t1/2

Bioequivalence to be concluded if the Cmax and AUCtau are within 80-125%.

Your views/guidance will be highly appreciated in this regard.

Best Regards,

Ratnakar
