A Global Comprehensive Review on Pharmaceutical Excipients

An excipient is a substance intentionally added to a medication for purposes other than its therapeutic or diagnostic effects at the prescribed dosage. Excipients are essential for ensuring proper consistency, controlling the solubility and bioavailability of active ingredients, and enhancing the stability of active components in the final dosage form. In many developed countries, excipients are regulated similarly to active pharmaceutical ingredients, and in Europe, innovative excipients are evaluated as new chemical entities. Excipients are evaluated and approved for use as part of new pharmaceutical applications due to the lack of consistent global regulatory criteria, the Food and Drug Administration has restricted some products from entering the United States. IPEC works with various countries, including Japan, to address common industry concerns such as global uniformity of excipient standards, the introduction of new excipients, and the development of safety evaluation criteria, with efforts from the USA, Europe, and China. An effort has been made in this work to examine major global problems with the regulations governing pharmaceutical excipients.
