Assessment of Bioequivalence
 Bioavailability:
In the bioequivalence study, bioavailability should be
compared for innovator and generic products.
 Parameters:
AUCt and Cmax
 Criteria:
The 90% confidence interval of difference in the average
values of logarithmic parameters to be assessed between
test and reference products is within the acceptable range
of log(0.80) - log(1.25).

 Q-27 Please describe the analytical validation in detail.
•
Stability of substances to be measured in samples under the storage
conditions (including freeze and thaw stability)
• Accuracy
• Precision (repeatability and intermediate precision)
etc...
Reference :
• V.P. Shah, et al.,Bioavailability, bioequivalence and pharmacokinetic
studies. J. Pharm. Sci., 81, 309 (1992).
• ISO 5725-6 Accuracy (trueness and precision) of measurement
methods and results - part 6: Use in practice of accuracy values.
