Restraints - Increasing Regulatory Stringency for Drug and Excipient Approval

The procedures for approving generic drugs are essentially the same everywhere, with minor variations in undeveloped countries. This is due to the fact that the world is not obliged to complete a bioequivalence (BE) research in order to receive generic medicine approval. Medical professionals assert that governments must guarantee the uniform quality of all generic medications. Only then can physicians be content and confident in writing generic medicine prescriptions.

Physicians' (and even patients') lack of trust in generic drugs has been largely attributed to weak regulatory standards governing the number of generic drugs and the number of permitted contaminants. Controlling the manufacturing and distribution of excipients is now a priority for authorities and medication manufacturers because combining excipients has resulted in adverse patient outcomes.

The development of new excipients and delivery technologies has also increased the importance of greater control over the supply and quality of pharmaceutical excipients in the context of in vivo activity.
