IPEC-Americas has just completed a major update to its significant change guideline to address current issues in the manufacture of excipient ingredients and to assist manufacturers in developing an impurity profile.

As newer and more elaborate hardware and software systems are installed in automated manufacturing environments, companies are further incorporating good practices into their validation process.

The authors evaluate the implications of product photosensitivity and how it influences various aspects of product development. They discuss a product photosensitivity classification system and present a photosensitive pharmaceutical product case study.

The author reviews dimensional analysis as a straight-forward approach to scale up.

The author describes strategies for analytical method development that are helpful in achieving quality by design and efficiency.

The author points out some major obstacles to effective scale-up and describes methods available to pharmaceutical scientists for addressing scalability issues.

In the manufacture of many pharmaceutical products, dry-particle blending is a critical step that directly affects content uniformity.
