Bioequivalence studies have to be executed using these requirements in an effort to prove that a NTI generic drug has precisely the same medical effects for a reference drug. Poor software of stricter bioequivalence requirements to non-NTI drugs would lead to bioequivalent generic drugs not staying accredited. Conversely, if a NTI drug was misclassified as non-NTI, common bioequivalence standards can be applied, As a result potentially resulting in the acceptance of the generic drug that has a more variable dose–exposure relationship than anticipated. For that reason, timely and correct identification of NTI drugs is an important Basis for bioequivalence tests. As an example, the NTI designation could arise at New Drug Application (NDA) approval.
