Already proven to be a useful tool in other industries, RFID may be the next innovative solution in product tracking and tracing.

Members of FDA, industry, and academia formed a working group within PQRI to openly discuss topics from a scientific perspective and provide formalized clarifications and recommendations to FDA to be considered and incorporated into FDA's draft guidance on aseptic processing.

The authors describe the solicitation of industry input for the guidance through a process that included a 2002 meeting of the Advisory Committe on Pharmaceutical Science and the subsequent formation of the PQRI Aseptic Processing Working Group.

Training for aseptic processing cleanrooms must be a dynamic process to meet job requirements and industry demands. The author discusses various approaches that may be taken to ensure a successful training session.

Modern tablet production facilities are faced with two increasingly important, yet contradictory, demands - being able to handle more potent drugs and, at the same time, reduce costs. Additionally, batch sizes must become smaller and production planning more flexible. Until recently, these issues could only be dealt with individually and not as a whole; however, the exchangeable functional module (EFM) may provide a solution to this problem, as this article describes.

This article is intended to keep readers informed about the developments concerning the local language requirements for European Union member countries. The first part deals with the reasons why these language requirements are about to become more difficult to meet and the second part, based on recent application knowledge, offers some potential solutions.

The authors provide a combined source of density data and show that denity can be used as an equipment-independent sclaing parameter in the manufacture of common pharmaceutical solids.

Oral dosage forms are the most popular way of taking medication, despite having some disadvantages compared with other methods. One such disadvantage is the risk of slow absorption of the active pharmaceutical ingredient (API), which can be overcome by administering the drug in liquid form and, therefore, possibly allowing the use of a lower dosage.

Flow problems, such as process performance and reliability, can be improved using a combination of experimental and computational methods.

Clarification processes are critical steps in production of biological products because they directly affect yield, product consistency, and reproducibility.

The recently issued FDA concept paper about aseptic processing shows how the current guidelines could be expanded and makes recommendations for alternatives to traditional cleanroom installations such as isolator-equipped aseptic filling lines and blow?fill?seal equipment.

As parenteral drug delivery becomes more complex and sophisticated, excipients that can facilitate drug (or gene) delivery to specific therapeutic targets will be required. An overwhelming majority of these excipients are derived from natural sources.

Flow problems, such as process performance and reliability, can be improved using a combination of experimental and computational methods.

When planning the installation of a new stainless steel process pipeline, it is important to understand the significance of using the best possible materials and techniques to ensure it is clean when installed. This article examines the factors that must be considered when planning and constructing a new process line.

Facilities with rigidly controlled environmental parameters can take steps to meet precise and repeatable conditions.

The influence of containment classification in facility design cannot be underestimated. It can, for example, determine the extent of the design process and the level of equipment needed to safeguard human life and the surrounding environment. This article discusses factors that should be considered when planning such a containment facility, including material flow, process equipment and regulatory guidelines.

Testing sterilizing grade filters using integrity testers has become a standard method in biopharmaceutical production and quality assurance. In accordance with international regulations and recommendations, these filters should be tested before and after filtration. For these applications, a variety of automatic integrity testers is available. Currently, there are two groups of devices that are used to conduct validated testing procedures, such as the bubble point test, the diffusion test, and the water intrusion test (WIT) and water flow test (WFT). Whereas one group of devices relies on the principle of flow measurement, the other group is based on pressure drop measurements. The following report compares the accuracy of the two test methods, using the WFT as a reference.

In the pharmaceutical and biotechnology sectors, the clean room business is flourishing. Accounting for approximately 25% of the world's clean room expenditure, Europe's drug manufacturing industry is using these facilities to produce an increasing amount of biologics and biopharmaceuticals, and meet the strict legislative requirements for aseptic processing. This article reviews the current and future state of the market for clean rooms in Europe and comments on their applications.

Closed and disposable sterility testing devices reduce the risk of false positive results during sterility testing. To further prevent such results, some pharmaceutical manufacturers use the device inside a sterility testing isolator, which is decontaminated using sterilant gases or vapours. In this study, closed, disposable sterility test devices were exposed to two 90 minute vaporous phase hydrogen peroxide (VPHP) decontamination cycles within a sterility testing isolator and tested for device integrity, bacteriostasis/fungistasis and non-volatile residue content. The results showed that the VPHP used to decontaminate the isolator before sterility testing did not affect the device.

Thousands of exhibitors and vendors showcase their packaging equipment and innovations.

Packaging technology is moving into the 21st century with innovative and cost-effective developments, including sound, moving images and even tracking devices. What was once deemed science fiction is rapidly becoming science fact. This article explores the latest developments in blister pack technology, discussing the range of benefits to both pharmaceutical manufacturers and patients.

Ultrafiltration is a pressure-driven membrane filtering process used to separate and/or purify dissolved or suspended particles from water and other liquids. Recent advances in materials and membrane manufacturing techniques have led to ultrafiltration playing a pivotal role in a number of biopharmaceutical processes, including protein concentration and blood for actionation. This article examines the criteria that should be considered when selecting membranes for such applications.

November's Contract Services articles include "Outsourcing Xbox Manufacturing," by Heather Hayes, "Outsourcing Outlook," by Jim Miller, and "Quality in Pharmacovigilance," by Brian Edwards and Jeffrey Priem.

Consideration of the key process variable will define the ease with which coating processes can be transferred from development to production. This study investigates those factors influencing atomization from two spray guns and examines how development-scale procedures on interchangeable drum coating equipment compare with those typically used in a production environment.
