The International Conference on Harmonization (ICH) Common Technical Document (CTD) format is the submission standard for new and abbreviated drug product applications in the United States, the European Union and Japan. One of the significant sections of the CTD is the Pharmaceutical Development Report (PDR). A complete PDR is essential to provide a comprehensive understanding of the product and process for the FDA application reviewers and inspectors. The information in the PDR is based upon the documentation generated during the formulation and process development phase of drug development.
