Quality by design approach: Regulatory need

In this era of competition quality has been given prime magnitude; failure to meet such quality allied goals produces massive shift of company in share of market. In this context pharmaceutical industry is utmost regulated industry as it is governed by authoritative regulatory bodies. "Quality could be planned and most of quality deficit arises in the way process is planned and developed'', this thought of well known quality expert Joseph Moses Juran gives foundation to the concept of quality by design (QbD). USFDA launched a pilot programme in 2005 to permit participating firms a prospect to submit chemistry, manufacturing, and controls (CMC) of NDA information representing application of QbD. Now USFDA is accelerating QbD drive by making warning to generic manufacturers from January 2013. QbD has its perspectives to contribute the drug design, development, and manufacture of high-quality drug products. In the present review basic consideration of the QbD approach, its historical background, and regulatory needs are discussed. In detail explanation of elements of QbD i.e. method intent, design of experiment, and risk assessment is given. Application of QbD to pharmaceutical and biopharmaceutical processes, development and unit operation associated with it are briefly mentioned. Detail account of QbD to analytical technique is explained thoroughly by referencing examples. (C) 2014 Production and hosting by Elsevier B.V. on behalf of King Saud University.
