摘要： A drug delivery system (10) includes a first capsule half (12) having an inner chamber (16) for containing a drug (18) therein. A plug (28) is disposed in a passageway (26) of the capsule half (12) for plugging the opening (24) thereof. The plug (28) is releasable from the passageway opening (24) upon the application of pressure from within the inner chamber (16). A pump mechanism, reactive with the external environment of the capsule half (12), causes an increase in pressure within the inner chamber (16) and forces the plug (28) out of the passageway (26) to release the drug (18) from the inner chamber (16) and out of the passageway (26). Thusly, after initial release of drug from a second capsule half (14) releasably mounted on the first capsule half (12), the first capsule half (12) provides a second pulse of drug release at a predetermined time after initial ingestion of the capsule. The invention further provides a method of manufacturing the drug delivery system (10) and method by which the drug delivery system (10) provides the drug to a body.
摘要翻译：药物输送系统（10）包括具有用于在其中容纳药物（18）的内室（16）的第一胶囊半部（12）。插塞（28）设置在胶囊半部（12）的通道（26）中，用于堵塞其开口（24）。在从内腔（16）内施加压力时，塞子（28）可从通道开口（24）释放。与胶囊一半（12）的外部环境反应的泵机构引起内室（16）内的压力增加并迫使塞子（28）离开通道（26）以释放药物（18）从内室16排出通道26。因此，在从可释放地安装在第一胶囊半部（12）上的第二胶囊半部（14）初次释放药物之后，第一胶囊半部（12）在胶囊初次摄入之后的预定时间提供药物释放的第二脉冲。本发明还提供了一种制备药物递送系统（10）的方法和药物递送系统（10）将药物提供给身体的方法。
