Automated and continuous synthesis of drug substances
Peer-reviewed journal | 24 Apr 2024 | Contributor(s):: Sacher, Stephan, Castillo, Ismael, Rehrl, Jakob, Sagmeister, Peter, Lebl, René, Kruisz, Julia, Celikovic, Selma, Sipek, Martin, Williams, Jason D., Kirschneck, Dirk, Kappe, C. Oliver, Horn, Martin
A continuous synthesis line was developed integrating different common reaction steps namely nitration, substitution and hydrogenation. Mesalazine as model drug substance was produced from 2-chlorobenzoic acid in continuous flow mode. A multi-instrument PAT strategy was implemented to equip the...

Granulation development in batch-to-batch and continuous processes from a quality by design perspective
Peer-reviewed journal | 09 Jun 2023 | Contributor(s):: Ko, Seung Jin, Lee, Ju-Hyun, Kang, Chin-Yang, Park, Jun-Bom
The process of quality by design (QbD) is of great importance in drug development. This review describes the design of experiments (DoE) method, which is an important component of QbD. DoE is predominantly divided into a screening phase and an optimization phase. The screening phase uses...
