Continuous Pharmaceutical Processes and Science-Based Manufacturing
November 9th 2005Continuous manufacturing processes?little used in the pharmaceutical industry but the norm in oil, food, chemical, and polymer manufacturing?go hand-in-hand with the current emphasis on quality-by-design and automated process monitoring and control (aka, process analytical technology, PAT).
Impacts of Process Analytical Technology
November 9th 2005The process analytical technology (PAT) initiative has been percolating at the US Food and Drug Administration for a long time, explained FDA's John E. Simmons at the AAPS Annual Meeting and Exposition on Wednesday. "If you think of PAT as an isolated set of applications, I think you are missing the point," Simmons said. "The FDA would like PAT to become commonplace?not to be an initiative, but common practice."
Taking the "Suspense" out of Nanosuspension Specifications
November 9th 2005Formulators currently face numerous challenges in nanosuspension development in terms of ensuring safety, efficacy, and stability. Presenters at Wednesday's AAPS symposium offered strategies for addressing these challenges, including setting meaningful particle-size specifications, selecting the method to measure particles in nanosuspensions (especially for nonspherical particles), gaining a meaningful particle-size distribution, and determining the particle size from such distributions.
Capabilities and Limitations of Molecular Simulation for Formulation Development
November 9th 2005As a pharmaceutical formulation tool, molecular simulation is currently in its early infancy. Nonetheless, presenters at Wednesday?s AAPS Annual Meeting and Exposition demonstrated that the technology is beginning to attract some interest. The topic was discussed in a presentation titled "Application of Molecular Simulations to Formulation Development and Stability Prediction."
