摘要：
The invention relates to floating drug delivery systems(FDDS) that provide solutions to the particular problems often encountered with floating drug delivery systems described in the art. On such generally recognized problem is the vulnerability of the systems, especially damage to the gas-filled compartment making it accessible to water so as to impair its buoyancy, ultimately resulting in insufficient gastric residence time. The invention, in an aspect, provides a self-repairing FDDS that maintains its floating capacity after damaging. The floating drug delivery systems of the invention, furthermore,allow for incorporation of high loads of active ingredients. The floating drug delivery systems can be designed in such a way that release of active ingredient from the system occurs entirely independent from the pH of the fluid surrounding the system. Furthermore, the procedure of manufacturing the floating drug delivery system of the invention is simple and straightforward, and therefore economically attractive.
