Patent number: 8637080Abstract: The present invention provides a simple and improved rupturing controlled release device that is capable of providing a controlled release of active agent contained in the core first through a preformed passageway and then through an in situ formed second passageway into an environment of use in a standardized release profile manner. The rupturing controlled release device comprises a core comprising at least one drug and at least one osmopolymer, a semipermeable membrane enclosing the core and having at least one preformed passageway there through, wherein the semipermeable membrane ruptures during use to form a second passageway in the semipermeable membrane at a location spaced away from the preformed passageway, and a release-controlling subcoat between the core and the semipermeable membrane.Type: GrantFiled: June 25, 2008Date of Patent: January 28, 2014Assignee: Osmotica Kereskedelmi és Szolgáltató, KFTInventors: Ana C.
