    Abstract:
    The Food and Drug Administration (FDA) is announcing the availability of a guidance entitled "Q4B Evaluation and Recommendation of Pharmacopoeial Texts for Use in the ICH Regions; Annex 1: Residue on Ignition/Sulphated Ash General Chapter.'' The guidance was prepared under the auspices of the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH). The guidance provides the results of the ICH Q4B evaluation of the Residue on Ignition/Sulphated Ash General Chapter harmonized text from each of the three pharmacopeias (United States, European, and Japanese) represented by the Pharmacopoeial Discussion Group (PDG). The guidance conveys recognition of the three pharmacopeial methods by the three ICH regulatory regions and provides specific information regarding the recognition. The guidance is intended to recognize the interchangeability among these texts from the local regional pharmacopeias, thus avoiding redundant testing in favor of a common testing strategy in each regulatory region. Elsewhere in this issue of the Federal Register, FDA is announcing the availability of a guidance on the Q4B process entitled "Q4B Evaluation and Recommendation of Pharmacopoeial Texts for Use in the ICH Regions."
