BA delivery system. The delivery system comprises 2 layers. (a) After disintegration of the Eudragit S100 coating, the system first releases a small dose immediately. This dose establishes a prosecretory and prokinetic BA level around the delivery system, facilitating further release from the controlled release layer. (b) The comparison of a (i) dissected pill and a (ii) dissected pill which was exposed to water for 5 minutes is shown to demonstrate the biphasic kinetic profile of this delivery approach. BA, bile acid.
