Summary:

      The purpose of this study is to evaluate the effectiveness, tolerability, and safety of
      oxymorphone immediate release (IR) oral liquid as an analgesic for acute postoperative pain
      in pediatric subjects.

      This post marketing study was required by the FDA. Endo Pharmaceuticals Inc. no longer
      promotes opioids and no longer markets Opana® ER.
