Regulatory requirements preformulation studies

Over the last 20 years, separation technology for analytical testing in the pharmaceutical industry has undergone great advances. This progress was motivated by the need for better quality products, the desire for improved knowledge in product development, and, in part, regulatory requirements. Separation techniques such as TLC, HPLC, GC, LC, counter current extraction (CCE), and capillary electrophoresis (CE) are extensively employed in preformulation studies. 

In this chapter, pharmaceutical and health-care products, such as prescription drugs, generic drugs, OTC products, animal health products, dietary supplements (vitamins and herbal drugs), and biotechnology-derived products, are discussed in relationship to the format of preformulation reports. Topics of the preformulation study are discussed in detail. Models for some of the reports are provided in the hope that the pharmaceutical development team will devise an individual report format based on particular needs and resources. Analytical techniques useful for preformulation and regulatory conformity or requirements relative to product registration processes are also enumerated.
