Coating technology has many applications in the pharmaceutical industry for taste masking and drug release control. Fluid bed coating is particularly suitable for smaller particles and pellets. In this article, Dr Harald Stahl, from GEA Pharma Systems, explains how the unique airflow within the Aeromatic-Fielder Precision-Coater™ can provide significant improvements in coating performance and overcome many of the coat quality and scale up problems experienced with traditional coating tubes.
The pharmaceutical industry has had technology that can coat particles in order to improve appearance, mask unpleasant tastes or to provide sustained release drugs for almost 50 years. However, with the dramatic rise in the number of drugs requiring this technology, and the increased cost of processing time and the compounds used, technologists are now under growing pressure to increase yield, improve coat quality and reduce process time.
