Bioequivalence scientific tests has to be executed utilizing these criteria so that you can verify that a NTI generic drug has the identical clinical results as a reference drug. Incorrect application of stricter bioequivalence criteria to non-NTI drugs would cause bioequivalent generic drugs not being approved. Conversely, if a NTI drug was misclassified as non-NTI, regular bioequivalence standards would be applied, Hence probably resulting in the approval of the generic drug that features a extra variable dose–exposure partnership than expected.
