This case study examines the benefits of introducing process information management software to a pharmaceutical pilot plant. The advantages illustrate the potential for process development and commercial manufacturing improvements that are available to the pharmaceutical industry.
With the advent of regulations such as 21 CFR Part 11 and the introduction of the electronic common technical document, it is becoming increasingly important to be able to enhance and fully utilize data management systems. Document change management is a vital tool in the construction and organization of valuable information, and can play a key role in the all-important process of getting a product to market.
Organic solvents are frequently used in the manufacture of active pharmaceutical ingredients. They have, therefore, normally also been used for process cleaning. However, a number of factors have encouraged the industry to change from solvent-based to aqueous cleaning. This article considers current cleaning practices, related issues and the author's experience of switching from one cleaning method to another.
Until specific audit trail requirements are available from the US Food and Drug Administration, manufacturers must define their own parameters for software system compliance and decide for themselves how to meet those requirements.
Previous articles have presented a general review of the different types of spheres that can be obtained using a rotary fluidized bed process.1,2 Part I of this study focussed on lipid spheres prepared using hydrogenated castor oil for formulations with low active drug content. The feasibility of the process and the main characteristics of spheres obtained were also studied. In Part II, formulations with higher concentrations of active drug are examined.
