In an aqueous environment, such as the gastrointestinal tract, the water-dispersible overcoat erodes quickly. The combination of the coating layers ensures an initial drug release, while delaying exposure of the matrix core. Upon attaining the intended pH, the delayed release coating dissolves, the hydrophilic polymers of the core hydrate and swell forming a gel like barrier that regulates the rate at which the drug is released from the tablet, ensuring a steady and prolonged delivery. chem structure
