Abstract
The present invention provides a simple and improved osmotic device ( ) that is capable of providing a controlled release of active agent contained in the core ( ) through a preformed passageway ( ) into an environment of use. The preformed passageway ( ) increases in size during use of the osmotic device ( ) thereby increasing the release rate of the active agent, enabling the release of large particles containing active agent, and enabling the release of active agents that are substantially insoluble in the environment of use.
