Packaging and Counterfeit PharmaceuticalsThere can be little argument that packaging is at the forefront of the fight against counterfeit drugs, which currently costs the industry between 6-10% of the value of pharmaceutical sales. According to IMS Health, the figure is approximately $22 billion from global pharmaceutical sales of $364 billion. To set this in context, counterfeiting of all goods costs $200-400 billion annually, claims the Global Anti-Counterfeiting Group. According to the the US Pharmaceutical Manufacturers Association, it can take an average of $250 million and 10 years to legally develop and market a drug, but it is possible for a counterfeiter to 'reproduce' a product within a couple of months for as little as $250000.

Automated Compliance: Reducing Costs and Maintaining QualityIn an interview earlier this year (Bio-IT World, April 2003), Janet Woodcock, director of the Center for Drug Evaluation and Research (CDER), stated that "The original intent of the rule (21 CFR Part 11) was to facilitate the introduction of electronic technology to the process of the US Food and Drug Administration (FDA) submissions, as well as manufacturing and production. Part 11 was created to provide common-sense guidelines on how to do in the electronic world what was previously done on paper. During the last 5 years, however, confusion regarding what is included in the regulation and how to enforce it was impeding the introduction of new technology. The rule had created exactly the opposite of what was intended."

Milling Made Easy: Nanoindentation as a Predictor of Bulk PropertiesSize reduction of materials through comminution is employed in many industries, including agrochemicals, minerals, ceramics and pharmaceuticals. The reasons for particle size reduction depend on the industry in question. Within the pharmaceutical industry, a large percentage of products are formed from powders and undergo processing to improve dosage form properties. Particle size reduction prior to compacting to tablets can aid with dissolution and homogeneity. Such processing of powders is, in part, dependent on their mechanical properties and balancing these properties is crucial in achieving desired manufacturing performance. Generally, pilot-scale milling trials are run to determine the most effective and efficient mill and operating conditions for each material. These trials, however, require relatively large quantities of material as well as time, and are normally run in early development when sufficient material becomes available. Hence, it would be highly beneficial to identify a physical property..

Maximizing Sample Information with High Sensitivity MSn and Fast Cycle Time on a Linear Ion Trap Mass SpectrometerRapid structural elucidation of compounds in complex mixtures is a powerful technique in metabolite, degradation and process control applications. The ability to follow the fragmentation pathway through sequential MSn transitions provides added confirmation and increases the selectivity for monitoring compounds of interest in a complex mixture. Previously, the limiting factors in applying this technique were sensitivity at MS4 and higher transitions, and the cycle time required to acquire multiple MSn spectra across a narrow LC peak. Recent developments in trapping, detection efficiencies and scan rates have reduced these limitations and enabled rapid characterization of multiple compounds from single chromatographic runs.
