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.
