Precision Coating Technology for Improved Yield, Enhanced
Product Quality, Reduced Process Time and Easier Scale-up
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.
Coating technology is used extensively in the pharmaceutical industry, e.g.
for the application of
non-functional or functional coats (aesthetic,
protective or rate controlling polymer films) and for
the deposition of
Active Pharmaceutical Ingredients (APIs) onto nonpareils (multi-particulate
dosage forms). In addition to efficient techniques for API layering of
multiparticulate systems, an accurate method of coating objects 3 to 30 mm in
length with APIs is also desired in the pharmaceutical industry as this is the
size range of most single-unit solid dosage forms. These include tablets for
oral administration and forms for other methods of delivery including human
implantation. Existing methods of coating objects in this size range have
limitations, e.g. in terms of coating speed and accuracy/uniformity,
particularly for the deposition of low dose API onto single unit tablet dosage
forms which requires a greater degree of accuracy than can be achieved using
current tablet coating techniques.
