The purpose of this study is to see if changing from one pain medication like morphine or oxycodone to another pain medication, oxymorphone (OPANA®), will be helpful to patients. This study will examine if the switching from one pain medication to another can be done over a 24 hour period. Oxymorphone, the drug being studied, is an FDA approved drug for treatment of severe pain.

Condition Intervention
Pain Drug: Oxymorphone

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Pilot Study of Rapid Opioid Rotation and Titration of Oxymorphone

Primary Outcome Measures:
  • Change in Patient Global Impression of Change [ Time Frame: baseline and 12 hours ]
    PGIC score - participants answered 2 questions regarding change in overall status and overall activity from baseline using a 7-point scale (1 = Very Much Improved, 2 = Much Improved, 3 = Minimally Improved, 4 = No Change, 5 = Minimally Worse, 6 = Much Worse, 7 = Very Much Worse)

  • Brief Pain Inventory [ Time Frame: Assessed daily for 10 days prior to IV PCA treatment, and assessed daily for 2 weeks after IV PCA treatment ]

Enrollment: 12
Study Start Date: November 2007
Study Completion Date: August 2008
Primary Completion Date: August 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: oxymorphone
participants switched to oxymorphone extended release (ER) via both oral and intravenous patient-controlled analgesia (IV-PCA) oxymorphone. After 24 hours, participants were discharged with oral oxymorphone ER and oxymorphone immediate release (IR) as needed
Drug: Oxymorphone
Other Names:
  • Oxymorphone PO
  • Oxymorphone IV
