USP applies metrological principles to the dissolution procedure alone and in collaborative studies to understand and minimize potential sources of variability.

There is a tremendous need to enhance delivery of potential therapeutics to the brain for treatment of central nervous system (CNS) disorders. The blood brain barrier (BBB) restricts and controls the exchange of compounds between the CNS and the blood, which requires discovery of new modalities allowing for effective drug delivery to the CNS. Polymer nanotechnology has now become one of the most attractive areas of pharmaceutical research. This review focuses on the current progress in polymeric nanoparticles, where the specific arrangement of the polymeric matter at the nanoscale is utilized to design drug delivery systems that provide safe and efficient transport of CNS drugs across the BBB.

The more experienced contract manufacturers go far beyond superficial process improvements, drawing on their own expertise and resources to improve the service, value and flexibility they offer their clients.

This article discusses a number of factors that may influence the behaviour of conjugated biopharmaceuticals. Optimizing bioconjugation processes may be critical to achieve the desired drug performance.

Key to the success of outsourcing stability studies is the relationship/partnership between the client and CRO. It involves a high degree of trust and mutual support

One of the major concerns with introducing PAT, however, is that the bias towards process engineering may not ultimately lead to complete control of product quality.

...Scotland has a favourable regulatory environment, funding support from its government and some of the most advanced research facilities in the world.

Green chemistry involves redesigning processes so that more of the raw material ends up in the product, rather than as waste...

Irradiation is an established method of sterilization for pharmaceutical products. Radiation sterilization can be achieved with gamma rays, electron beams, and X-rays. Each of these techniques has its advantages and disadvantages. The author describes these methods, the ways to find the correct sterilization doses, and the regulatory and safety concerns about irradation sterilization.

Validating the sterilization process is extremely important in pharmaceutical manufacturing. The authors explore different types of sterilization processes and discuss the importance of finding the worst-case positions of loads or equipment to be sterilized and the worst-case conditions for each sterilization cycle. Biological indicators (BIs) can be used to simulate worst-case scenarios and determine the effectiveness of a particular sterilization process.

Pre-use integrity testing of sterilizing-grade filters eliminates the potential adverse effects of filter loading on the integrity-test results, allowing unambiguous correlation with the integrity-test specification established during filter-validation studies.

A biological indicator (BI) measures the effectiveness of the sterilization process to which it is subjected. Factors such as the test organism, the packaging, the culture material, and the test system all influence a BI's resistance. Carrier material is an often-overlooked factor that also influences BI resistance. The authors examine various solid and liquid carriers, describe their properties, and investigate how they influence BI resistance.

The author clarifies the definition and objectives of overkill sterilization for steam sterilization cycles. Current sterilization practices are reviewed and the validation difficulties associated with the various definitions of overkill sterilization are explored.

Aseptic processing has advanced over the past several decades, yet the pharmaceutical industry is still accepting of its limitations, particularly as it relates to human intervention as a source of contamination. The authors explain the importance of further diminishing the role of operators in aseptic processing and the approaches and technologies needed to achieve that goal.

A roundup of company moves and positioning from the pharmaceutical industry and biotechnology industries and contract service providers.

Basel, Switzerland (Apr. 26)-Roche outlined advances it is production strategy for "Tamiflu" (oseltamivir) for treating the H5N1 avian influenza virus.

London (Apr. 23)-AstraZeneca PLC agreed to acquire MedImmune, Inc. for approximately $15.6 billion. The deal is expected to close in June 2007.

New York (Apr. 26)-Bristol-Myers Squibb Company and Pfizer, Inc. entered into a collaborative agreement for the development and commercialization of apixaban, an anticoagulant that BMS discovered.

Interphex2007, New York, NY (Apr. 26)-Robustness studies for analytical methods are critical in being able to provide the assurance to the quality of an analytical method, a topic addressed in a conference session, "Performing Analytical Method Validation Robustness for Regulatory Compliance," at Interphex on Thursday.

Interphex2007, New York, NY (Apr. 26)-Maintaining reliable equipment in pharmaceutical manufacturing operations is critical not only for achieving productivity goals and safety, it also is a prerequiste for moving operations to a lean-manufacturing environment.

Interphex2007, New York, NY (Apr. 26)-As focus shifts away from "one-size-fits-all" medicines and begins centering on personalized medicines, many companies begin to wonder how they can manufacture such drugs economically. Mark Hirschel, chief scientific officer of BioVest International, addressed that issue in his presentation, "A Bioreactor System Designed for Production of Personalized Therapeutics," at Interphex on Thursday.

Interphex2007, New York, NY (Apr. 26)-Counterfeit medicines are of increasing concern to the pharmaceutical industry, both because of the potential health risks to patients and because of the effects on pharmaceutical companies' businesses. While technology such as e-pedigree and radio frequency identification (RFID) represent solutions to secure the supply chain, there are challenges.

Interphex2007, New York, NY (Apr. 25)-As manufacturers prepare for processing more-potent compounds, they seek effective clean-in-place (CIP) and wash-in-place (WIP) design systems.

Interphex2007, New York, NY (Apr. 25)-One of the challenges facing pharmaceutical manufacturers is how to implement process analytical technology (PAT) into their commercial manufacturing processes. Michael Abad, engineering section manager, Abbott Laboratories shared insight from a project within Abbott in his presentation "Engineering for PAT" at Interphex today.

Interphex2007, New York, NY (Apr. 25)-As governments begin to contemplate the possibility of biological terrorism or a pandemic event, a new problem begins to emerge: in the case of a pandemic or an attack, even if a vaccine or treatment exists, how could it be produced in sufficient numbers to prevent the deaths of millions of people? That question was addressed in at the conference session, "Responding to Bioterrorism and Pandemic Events: A Case for Development of Flexible Manufacturing Space for Vaccine Production," at Interphex today.
