This year's fall conference season clearly shows that the new, systematic approach to process planning and product quality is permeating the industry's thinking—if not yet its daily practice.

A new oral dosage product was designed as "encapsulated tablets." In production, the drug product was pressed into tablets, which were then fed into a revolving capsule-filling table.

From politics to paychecks and downsizings to deadlines-what it's like to work for one of the world's largest industries.

If judges and juries lack the scientific knowledge to decide drugsafety cases, how can we protect both companies and patients?

Roche (Basel, Switzerland, www.roche.com) has put a temporary halt on the distribution of the antiviral treatment, "Tamiflu" (oseltamivir phosphate), a neuraminidase inhibitor, to the United States in an effort to deter companies from stockpiling the antiviral for employee use, according to an article in the Oct. 27 edition of The New York Times.

First, a confession. Yes, the four sleep-deprived editors hunched behind glowing laptops in the Opryland Resort's Cyber Café last month were indeed from this publication. Normally, our mumbled conversations about punctuation and grammar take place before 11:00 pm—and under slightly lower systemic levels of caffeine, sugar, and sushi.

The attraction of nasal administered therapeutic agents is obvious, including faster onset of action, increased compliance and avoiding degradation during first pass metabolism.

With the prospect of a possible pandemic the Swiss company, Roche, has found sales of its flu drug have rapidly increased but its patent is being questioned. Roche's Tamiflu sales have inflated by 263% in the first 9 months of this year but discussions of patent suspension from several countries and United Nations Secretary General Kofi Annan is pressurizing the company.

The introduction of new measures on advertising and promotional materials for prescription medicines could delay UK launches. The Medicines and Healthcare products Regulatory Agency (MHRA) has admitted that the checks, which have been introduced in response to a Commons' Health Select Committee report, could extend a launch by at least 2 weeks.

Continuous 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).

The 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."

This week, the US Food and Drug Administration posted an Oct. 20 Warning Letter (http://www.fda.gov/foi/warning_letters/g5567d.htm) sent by its Minneapolis, MN district office to Diversified Manufacturing Corporation (Newport, MN).

CDER 2005 Product Approval Totals Proposed CDER Reorganization

Formulators 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.

As 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."

Control Development's (South Bend, IN, www.controldevelopment.com) blend uniformity and dryer monitor consists of a NIR spectrometer, a sampling head, computer, and software.

After outlining the results of extensive studies on drug-silicate interactions, Robin H. Bogner, PhD, concluded, "We're just scratching the surface." She might have added, "pardon the pun": the effect of silicates' heterogeneous surface chemistry is one of the points of study.

Artium Technologies' (Sunnyvale, CA, www.artium.com) new diode-pumped phase Doppler interferometry systems use solid-state lasers incorporated into transmitting optics, eliminating losses that can result from fiber coupling, alignment, and degradation. According to Atrium, the advantage of this approach to optical design is improved precision and a larger dynamic range, with higher resolution over the entire range.

In the spirit that a good review of the fundamentals is always beneficial, the American Association of Pharmaceutical Scientists' Annual Meeting and Exposition featured an early morning discussion about the basic aspects of dissolution testing, including common sources of errors and deviations. The well-attended session proved that dissolution testing remains a topic of interest, especially as the industry continues to extend its application to media other than solid dosage forms, most notably soft gels.

The International Organization for Standardization (ISO, www.iso.org) has approved the use of the photometric method for liquid delivery performance verification. Artel (Westbrook, ME, www.artel-usa.com), a manufacturer of precision testing and calibration systems for liquid handling instruments, uses the photometric method to calibrate pipettes and automated liquid handlers.

Extending the life cycle of a drug product has paved the way for "the new pharmaceutical industry" according a Tuesday AAPS Annual Meeting session, "Formulation Approaches to Life Cycle Management."
