Title of Invention | GASTRIC RETENTION CONTROLLED DRUG DELIVERY SYSTEM |
---|---|
Abstract | The present invention provides a gastric retention controlled drug delivery system comprising a controlled release core comprising a drug, a highly swellable polymer and a gas generating agent, said core being capable of swelling and achieving floatation rapidly while maintaining its physical integrity in gastrointestinal fluids for prolonged periods, and a rapidly releasing coat composition comprising the same drug as in the core and pharmaceutically acceptable excipients, wherein the coating composition surrounds the core such that the system provides a biphasic release of the drug in gastrointestinal fluids. |
