What ICH Q4B: Evaluation and Recommendation of Pharmacopoeial Texts for Use in the ICH Regions requires
ICH Q4B provides a framework for evaluating Ph. Eur., USP, and JP pharmacopoeial general chapters to determine interchangeability across ICH regions, reducing duplicative testing. Annex 1 through Annex 16 cover specific topics (residue on ignition, particulate contamination, microbial limits, etc.). Interchangeability declarations are accepted by EU, FDA, PMDA, and Health Canada. Compliance reduces regulatory complexity for global drug development by allowing use of any approved compendial method.
