Bioequivalence experiments need to be executed applying these criteria so as to show that a NTI generic drug has exactly the same medical results as a reference drug. Incorrect application of stricter bioequivalence requirements to non-NTI drugs would bring about bioequivalent generic drugs not currently being authorized. Conversely, if a NTI drug was misclassified as non-NTI, normal bioequivalence standards could be used, Hence most likely leading to the acceptance of the generic drug that features a more variable dose–publicity connection than expected. Therefore, well timed and proper identification of NTI drugs is a crucial Basis for bioequivalence tests. As an example, the NTI designation could arise at New Drug Application (NDA) approval. Generic drugs Engage in a major position in well being treatment and each precise bioequivalence and therapeutic index facts are needed for best dosing.
