Process Patent Protection: Characterizing Synthetic Pathways by Stable-Isotopic Measurements
March 2nd 2007The authors describe the methods by which precise analyses of stable-isotopic abundances can be used in security and forensic applications for pharmaceutical materials. These methods include product and process authentication of raw materials, pharmaceutical intermediates, drug substances, formulated drug products, and synthetic pathways. Collectively, these methods can be used to investigate and mitigate patent infringement. In the future, more complete examples will be presented containing full isotopic results and the application of the methods described in this article.
The Advantages of Restricted-Access Barrier Systems
March 2nd 2007Filling machines often are installed in sterile rooms and separated by isolators to prevent contamination. These methods have certain drawbacks, including making interventions more difficult. Restricted-access barrier systems are an alternative that ensures sterility and facilitates interventions.
