Too Little and Too Much

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.

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.

The monopoly held by the large pharmaceutical companies within drug discovery could be falling into the hands of biotechnology firms claims Frost and Sullivan. The consultancy company's report, Biochips Technology Redefines Process of Drug Discovery, states that biochip manufacturers are encouraging end users to accept the new technology by providing novel and effective solutions.

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."

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."
