In Part I of a three-part article, the authors discuss what constitutes an impurity and the potential sources of impurities in APIs and finished drug products.

Technology may expedite operations, but the absence of the human element could cost dearly.

The European Union market takes steps toward continuous processing and modular facilities.

PharmTech's monthly newsletter, Equipment and Processing Report, reviews the Editor's Picks for the December 2011 edition from Banner Engineering and Eriez.

Risk assessment is not a new concept to the pharmaceutical industry, but lately the phrase has become a mantra. A systemic, science-based way to manage risk is becoming essential to meeting the spirit and letter of FDA requirements.

Cleanliness is crucial, even if zapping and trapping is necessary to reduce product contamination.

The seventh in a series of eight case studies from the Product Quality Research Institute focuses on packout remedies.

Drug shortages, supply-chain security, generic-drug incursion, and flexible manufacturing models are some of the issues shaping the bio/pharma industry.

Precedents set in the historic Barr case continue to raise questions over suitable sample-size criteria.

Readers react to the economic turmoil of the past year and look longingly forward to 2012.

The last in a series of eight case studies from the Product Quality Research Institute focuses on internal GMP audits.

The sixth in a series of eight case studies from the Product Quality Research Institute focuses on packaging line GMP optimization.

On Sept. 27, 2011, FDA sent Genentech a Form 483 listing several violations at the company's South San Francisco, California, plant. The violations included problems with investigations into batch failures, inappropriate equipment design, and insufficient protection against contamination. FDA visited the plant, which produces the cancer drug Avastin, 13 times in September 2011 and made four observations.

Careful mixing during a product's distillation can help avert trouble from a strong concoction.

New product reviews for November 2011.

The authors describe the operational qualification of test accuracy with regard to temperature drift using a thermal-compensation algorithm on several freeze dryers.

The fifth in a series of eight case studies from the Product Quality Research Institute focuses on nonsterile facility cleaning requirements.

The US Pharmacopeia (USP) proposes to lower the maximum permissible limits of trace elements in pharmaceuticals and recommends that impurities be measured through automated instrumentation-based methods. The proposed regulations specify inductively coupled plasma–mass spectrometry (ICP–MS) and inductively coupled plasma–optical emission spectrometry (ICP–OES) as the techniques of choice. This article discusses the benefits of ICP–MS and ICP–OES for the accurate detection of trace elements in pharmaceutical products, in compliance with the proposed USP chapters.

The authors discuss the analytical methods and related testing for bioequivalence studies of ADCs.

Combining olfactometry analysis with multidimensional gas chromatography–mass spectrometry provides an extremely useful analytical method for identifying aroma or odor notes from a sample.

A Technical Forum Moderated by Patricia Van Arnum, featuring contributions from PerkinElmer, BioTools, Chiral Technologies, Shimadzu Scientific Instruments, GE Analytical Instruments, and Waters.

This article focuses on the history of glass delamination and methods that detect it, both from a compendial and a research perspective.

The authors discuss the analysis of the resulting data, focusing on methods for the calculation of mass median aerodynamic diameter, one of the metrics routinely used for comparative testing.

The authors investigate the effect of low pH and ionic strength on aggregation using turbidity measurements and size-exclusion–high-performance liquid chromatography.

The authors describe the benefits of nuclear magnetic resonance (NMR) compared with traditional monitoring techniques. They also discuss how NMR reaction monitoring provides a new process analytical technology tool for industry.
