Abstract :

Quality by Design (QbD) has brought a great sense and discipline to drug product development, for both branded and generic drug products. One ought to keep the design parameters and scope of QbD in proper perspective while applying it to generic drug development. In quest to circumvent patents protecting brand drug products, generic drug development has taken on a whole different path and in many cases it is getting closer to brand drug formulation development. Some of the generic drug products bear little resemblance to brand drug product formulations. This topic will be discussed with examples. A lack of full appreciation for QbD and making short cuts in the developmental process in order to catch a certain date to submit drug applications often make it difficult for reviewers to process drug applications in a timely manner. Review of a generic drug application, ANDA, should essentially be on ?auto-pilot? and should really not take more than 6-9 months of review time. Getting refuse to file (RTF) letters for ANDAs leaves a lot to desire in terms of quality of drug development and documentation. Yet as we all know, many applicants receive RTF letters from the FDA, there is tremendous back log, and the review times are lengthy. It can take as much as 36 months to get an ANDA reviewed and approved. Some key reasons of such back logs and lengthy review times and ways to improve will be discussed. Some common GMP problems will be highlighted and discussed
