Investigating the effect of processing parameters on pharmaceutical tablet disintegration using a real-time particle imaging approach.

Tablet disintegration is a fundamental parameter that is tested in vitro before a product is released to the market, to give confidence that the tablet will break up in vivo and that active drug will be available for absorption. Variations in tablet properties cause variation in disintegration behaviour. While the standardised pharmacopeial disintegration test can show differences in the speed of disintegration of different tablets, it does not give any mechanistic information about the underlying cause of the difference.
