  • System for osmotic delivery of pharmaceutically active agents
    Patent number: 6838093
    Abstract: An osmotic system for delivering a pharmaceutically active agent which comprises a core portion, a layer portion enclosing the core portion, and a semipermeable wall portion enclosing the core portion and the layer portion. The core portion includes the pharmaceutically active agent at a first concentration. The pharmaceutically active agent is present in the layer portion at a second concentration. The second concentration is greater than the first concentration. Such a system provides for the osmotic release of the pharmaceutically active agent in release profile other than a zero order release profile, and wherein the release profile is similar to or approaches or reaches a first order release profile.
