Abstract: Disclosed is a misuse preventative, controlled release formulation comprising a core comprising a superabsorbent material (for example, polycarbophil), a controlled release coat surrounding the core, and a plurality of controlled release microparticles having a pharmaceutically active agent (for example, an opioid analgesic) disposed within the core, the coat, or both the core and the coat. When crushed, either intentionally or accidentally, and exposed to an aqueous medium, the superabsorbent material present in the core swells to encapsulate the microparticles, which remain substantially intact thereby retarding the release of the pharmaceutically active agent from the formulation. Also disclosed is a method of using the misuse preventative, controlled release formulation to deliver a pharmaceutically active agent to a mammal, for example, a human, in need thereof.

Abstract: The invention relates to a once a day formulation of trazodone or a trazodone derivative. The formulation contains trazodone or a trazodone derivative and a controlled release excipient so that, once administered orally, the trazodone or the trazodone derivative is maintained at a therapeutic plasma concentration from at least 1 hour to at least 24 hours after initial administration. After administration, the initial therapeutic action takes effect within the first hour and lasts at least about 24 hours. This therapeutic effect remains relatively and substantially stable for the remaining period of 24 hours. The formulations can be used for treating depression and/or sleeping disorders.

Abstract: Disclosed is a misuse preventative, controlled release formulation comprising a core comprising a first layer and a second layer. The core comprises a superabsorbent material (for example, polycarbophil), and a plurality of controlled release microparticles having a pharmaceutically active agent (for example, an opioid analgesic) disposed within the core. When crushed, either intentionally or accidentally, and exposed to an aqueous medium, the superabsorbent material present in the core swells to create a hard gel that traps the microparticles. The hard gel and microparticles provide controlled release of the pharmaceutically active agent. Also disclosed is a method of using the misuse preventative, controlled release formulation to deliver a pharmaceutically active agent to a mammal, for example, a human, in need thereof.
