There is a great need for sensitive, precise, and easily accessible analytical detection techniques for protein sequencing.
Frequency Modulation Spectroscopy
October 2nd 2005Frequency modulation spectroscopy is a nondestructive technology for determining the water activity of pharmaceutical samples. This article discusses the various pharmaceutical applications of frequency modulation spectroscopy, offers comparisons with various traditional water activity measurement techniques, and presents an assessment of various instrument performance elements.
Pharmaceutical Dust Extraction and Vacuum Cleaning
October 1st 2005Dust extraction and centralized vacuum cleaning systems vary in their design, performance and costs. Different companies have different approaches to their design, however, there are some basic rules that must be followed if these systems are going to be immediately effective and avoid future problems.
Analytical Method Equivalency: An Acceptable Analytical Practice
September 2nd 2005Participants in a 2003 PhRMA workshop present the industry’s current thinking on developing analytical method equivalency, including the importance of sample selection, acceptance criteria, data evaluation, and documentation.
The Future of Metered-Dose Inhalers
September 1st 2005IAdvances in pressurized metered-dose inhalers (pMDIs) in terms of formulation capability and the performance of the container closure system enable products to be developed faster and with less technical risk. Despite new delivery devices for new molecules breaking into the pMDI market, pMDIs have the ability to gain regulatory approval significantly faster than a novel device, which could save a company many hundreds of millions of pounds.
Planning and Designing a Pharmaceutical Facility: A Process Designer's View
September 1st 2005Planning manufacturing capacity in the pharmaceutical industry is not for the faint-hearted. How can process designers help their clients to overcome some of the problems they face when planning to introduce new capacity? This article sets out to explain some of the techniques that are being employed in the early stages of project development.
Variable Air Velocity within Stability Chambers A Possible Cause of Out-of-Trend Stability Results
August 2nd 2005Stability data that do not follow the expected trend in comparison with other stability batches or previous results collected during a stability study are considered out-of-trend (OOT) results. OOT stability results recently have gained the attention of regulatory agencies and as a result, the approach for identifying and investigating OOT results has become a topic of increased discussion. One example is a 2003 article by the PhRMA Chemistry, Manufacturing, and Controls Statistics and Stability Expert Teams, which was intended to initiate dialogue on how to address OOT results (1).
Revisiting The Notion Of Singlet Testing Requirements
June 2nd 2005In his Feb. 2005 viewpoint article, "In Defense of Singlet Testing," Torbeck (1) draws an important philosophical distinction between "standards" and "specifications." He argues that specifications are criteria selected by manufacturers for statistical control of their products, whereas compendial standards are absolute requirements. This distinction is entirely compatible with modern concepts of statistical process control.
Designing & Implementing Pharmaceutical Clean Rooms
June 1st 2005Possible cross-contamination issues should be eliminated at the early stage of the project. The project sponsor should ensure that all relevant personnel from the production, quality control, logistics, and maintenance departments, as well as engineering, are involved in the conceptual stages of a design.
Sieve Use in the Pharmaceutical Industry
May 1st 2005Asieve or screener is an essential part of every pharmaceutical production process, particularly as product quality and integrity are so important. The use of a sieve gets rid of oversized contamination to ensure that ingredients and finished products are quality assured during production and before use or despatch.
Transforming Development Productivity Using Integrated Automation
May 1st 2005The FDA initiative —Process Analytical Technologies (PAT) — is slowly gaining momentum, creating a revolution in manufacturing and testing processes that aims to ensure product quality. Its growth will encourage faster testing techniques to bring analytical testing closer to on- and at-line testing during the product manufacturing process.
Glass Reactor Vessel — Value Sealing Innovation
May 1st 2005Active pharmaceutical ingredients (APIs) have become more potent, therefore the requirements of good manufacturing practice (GMP) are making ever more stringent demands on valve design and sealing. An absence of dead space, ease of cleaning and flushing is the norm for valves where cross contamination must be avoided at all costs. Sealing valves to glass reaction vessels has lagged behind valve sealing for steel vessels.
