The Pharma Crystallization Summit (PCS) is held annually to bring together developers of new medicines with crystallization challenges and the crystallization experts (solution providers) in the industry and academia. PCS programs are designed to stimulate in-depth discussions on common and/or leading bottleneck issues related to crystallization of drug substance (DS) as well as the intermediates, the technologies and solutions that are available or underdevelopment. The discussions help new medicine developers to make educated and phase-appropriate decisions, and crystallization experts to understand better the critical needs for providing effective solutions.
