Continuous Tablet Coating with high-solids coatings.
This article discusses how high-solids coating systems can shorten processing times and reduce energy usage while meeting the requirements of today’s pharmaceutical products. High-solids coatings can also facilitate adoption of continuous coating.
The growing appeal of continuous coating processes has occurred in no small part because 1) O’Haras innovative zero waste system for start-up and shut-down and 2) it is possible to operate the Fastcoat™ continuous coater in batch mode. Yet one big challenge of continuous coating has remained: The short residence time of tablets within the coating pan (typically 15 to 25 minutes). This short period imposes a significant burden on the ability to deposit the requisite amount of coating material. High-solids coating systems resolve this problem and make available the major benefits of continuous coating, including:
- Rapid throughput (with shorter coating process times).
- Less exposure to harsh processing conditions.
- More uniform distribution of the coating material and Less coating material required.
