In this study, the authors investigated the compression behavior of excipients with different molecular weights using the modified Fraser-Suzuki function and correlated the S-parameter of this function with Young's modulus.

The benefits of using computers and electronic records are proven in most fields of modern-day work, none more so than in laboratories. The opportunities for automation have improved productivity; the computational abilities have increased the accuracy of scientific data and allowed previously difficult or impossible analytical techniques to become routine affairs. This, in turn, has led to huge advances in drug discovery and in the chemical, biochemical and physical analysis of drugs and patients.

Using melt extrusion to prepare glass solutions of poorly water-soluble drugs with hydrophilic excipients offers an exciting and advantageous alternative to existing formulation methods such as spray-drying and co-melting. Investigating potential methods to increase water solubility begins early in drug development. Techniques described in this paper show how only a small quantity of drug can be used to determine its suitability for melt extrusion, allowing the method to be considered at the same time as salt screening and particle size reduction work, and could speed up the formulation process.

A limit test using ion mobility spectrometry (IMS) has the potential to dramatically reduce the time required for cleaning verification and cleaning method development. The traditional approach to cleaning verification, often using HPLC, is relatively resource intensive and can lead to significant delays in reporting results. The main advantage of IMS is that results are seen virtually instantaneously, so any necessary re-measurement can be done very quickly. If the results demonstrate cleanliness, production can resume in a matter of hours not days.
