Changes concerning active ingredients
The Guidance for Industry BACPAC I: Intermediates in Drug Substance Synthesis, Bulk Actives Post-approval Changes: Chemistry, Manufacturing, and Controls Documentation, published in draft form in November 1998, has now been approved in its final version by the Food and Drug Administration (FDA) and has been in effect since February of this year.
BACPAC I gives recommendations for dealing with changes of manufacturing site, batch size, equipment, specifications and manufacturing processes in the manufacture of synthetic active ingredients and for the synthetic manufacturing steps for active ingredients obtained by semi-synthetic means.
Any change in the manufacturing method of active ingredients harbors the risk that the quality of the final product may be changed, e.g. the physical properties of the active ingredients (e.g. polymorphy) or the contamination profile. The risk here that the quality of the final product will be influenced is greater the later in the manufacturing process that this change is made. The core of the BACPAC guide is the following decision tree, which defines the area of application of BACPAC.

In view of other changes concerning active pharmaceutical ingredients we would like to draw your attention to this year's 4th APIC/CEFIC European Conference on Active Pharmaceutical Ingredients which is to take place in Vienna from September 26 - 28, 2001. This year's conference will include a GMP and a regulatory affairs segment.
From FDA Dr. Yuan-yuan Chiu has already agreed to speak on the topic of "New developments of post-approval changes". In addition to BACPAC, of course the GMP Guide ICH Q7 and TSE and falsification of active ingredients will be an important topic.
In this year too the European Chemical Industry Council (CEFIC/APIC) will be organizing this event and has invited both European and North American opinion-makers to Vienna. This year service providers will have the opportunity for the first time to take part to a limited extent in an integrated exhibition.
