FDA's recently released initiative has made process analytical technology (PAT) a hot topic in the life science industry. PAT describes the application of process analytical chemistry tools, feedback process control, information management tools, and product and process optimization strategies for the development and manufacture of pharmaceuticals. In this article, the author explores the impact PAT will have on the pharmaceutical industry.

This article examines automated artwork generation, which enables pharma companies to generate validated artwork for their products' packaging. Automated artwork generation is based on a complete set of data stored in an artwork management system. It enables the dynamic assembly of artwork documents, accelerates traditional processes and significantly reduces costs.

The process of extrusion/spheronization used to produce spherical granules frequently relies on formulations containing microcrystalline cellulose (MCC). This excipient can hold water, even when pressure is applied, and form "pastes" that have suitable rheological properties, which allow both extrusion and subsequent spheronization to produce uniform spherical granules. This article describes a new approach to providing paste systems with appropriate characteristics. This can be achieved by incorporating glyceryl monostearate (GMS) into the formulation. It was found that the inclusion of GMS in formulations provides a useful alternative to MCC as an effective excipient to aid the preparation of spherical granules, allowing the incorporation of drug loads as high as 90%.

This article describes the quality of highly purified water and its applications, addressing why ultrafiltration (UF) is being used as a downstream purification process. It aims to show that UV is a real alternative for producing pyrogen-free water. This method allows essential cost savings compared with distillation and guarantees a higher safety than other membrane methods such as reverse osmosis.
