Dissolution Profiles of Generic Products in Dissolution Media Defined by Japanese Guidelines for Bioequivalence Studies.

The International Conference on Harmonisation (ICH) of Technical Requirements for Registration of Pharmaceuticals for Human Use M9 Guidelines for Biopharmaceutics Classification System Biowaivers reached harmonization in November 2019. However, guidelines for bioequivalence studies are not internationally harmonized, and water as a dissolution medium is only required in Japanese guidelines, regardless of drug solubility. This study investigated the dissolution profiles of generic products in Japan that differ from those of original drugs in dissolution media defined in guidelines.

Impact of Quality by Design Development on the Review Period of New Drug Approval and Product Quality in Japan.

Background: For pharmaceutical products, an in-depth understanding of manufacturing processes and quality risks associated with quality by design (QbD) development enables the production of high-quality products. Product recall due to quality issues could be minimized for QbD-developed products. Furthermore, the review period instituted by regulatory authorities could be shortened by allowing reviewers to access technical documents with QbD elements.
