Manufacturing

Understanding the impact of reactive mass transfer and local flow in multiphase systems is crucial for maximizing reaction selectivity and minimizing the formation of byproducts. The authors study the influence of mixing on fast liquid–liquid reactions. The iodination of L-tyrosine was used to demonstrate the relationship of droplet size and shape on reaction selectivity and to verify computational predictions. By understanding that droplet dynamics affect the yield and selectivity of fast reactions, the formation of byproducts can be minimized by optimizing operating parameters.

The trend towards developing pharmaceutical products and their manufacturing processes in tandem supports optimized production. Such developments rely on gathering process-relevant information at an early stage and being able to draw on past and current processing experience. Here, we discuss how powder rheometers can make a real difference in building a database of powder properties and removing subjectivity.

Clean rooms are critical areas in bio/pharma facilities, and it is essential that users are responsible for their care and upkeep, and familiarize themselves with the relevant regulations.

Quality by design and PAT approaches are increasingly being used for the biotech manufacturing of medicines. Complex manufacturing processes can not only be controlled using PAT principles, but optimized with respect to both product quality and economic value. This column describes how the fermentation process is often the first to benefit from this type of implementation.

The ¤9.5 billion therapeutic antibody market comprises over a dozen antibodies that have been generated using recombinant genetic methods developed over the last 20 years.

This article examines what other industries have done to address the challenges associated with successfully implementing the principles and concepts of process analytical technology, particularly the specific elements of measurement, analysis, and control. The author explores how other industries' approaches can be applied directly to pharmaceutical manufacturing.

Modeling conducted in the process development and early commercialization stages can increase process efficiency and lead to process-control improvement. A virtual plant environment, running on a PC, can incorporate the same industrial control systems and configuration expertise used in manufacturing and helps many parts of process analytical technology. It also can make possible the enlightened use of technologies such as model predictive control, first-principal models, neural networks, and multivariate statistical process control.

The US Food and Drug Administration issued a guidance document to provide manufacturers of biological products (other than blood and blood components) with its current thinking on reporting requirements on deviations from current good manufacturing practices for biological products.

Growth in the global pharmaceutical market is expected to slow in 2007, based on the industry's increasing reliance on niche and specialty products and greater generic drug penetration, according to a forecast by IMS Health. Generic drugs, along with biotechnology and specialist-initiated products, are expected to outperform the overall market in 2007. Despite slower growth in the United States and Europe, growth in emerging countries, including China, is projected in the double digits.
