Abstract
Disclosed is a misuse preventative, controlled release composition in the form of a multilayered oral dosage form. A first layer contains a plurality of controlled release microparticles having a pharmaceutically active agent (for example, an opioid analgesic) disposed therein. A second layer comprises a superabsorbent material. When crushed, either intentionally or accidentally, and exposed to an aqueous medium, the superabsorbent material creates a hard gel that traps the microparticles. The hard gel and microparticles provide controlled release of the pharmaceutically active agent.
