Purpose

Opioid medications are commonly used for pain relief. When given over time, physical dependence can occur. This results in unpleasant side effects (such as agitation and nausea) if opioid medications are suddenly stopped. This study aims to test the use of the drug ondansetron to reduce the symptoms associated with opioid withdrawal and to prevent the progression of opioid physical dependence, thereby allowing future investigators to better test the role of physical dependence in the development of addiction and also possibly improving acceptance of abstinence-based programs for addiction.
