Primary Outcome Measures:
  • The Number of Participants With Adverse Events as a Measure of Safety and Tolerability [ Time Frame: 6 months. ]
    Safety was assessed using reports of adverse events, clinical laboratory results, findings from physical examinations, and vital sign measurements.


Enrollment: 290
Study Start Date: April 2003
Study Completion Date: July 2004
Primary Completion Date: July 2004 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: BTDS
Buprenorphine transdermal patch
Drug: Buprenorphine transdermal patch
Buprenorphine transdermal patch 5 mcg/h applied for 7-day wear
Drug: Buprenorphine transdermal patch
Buprenorphine transdermal patch 10 mcg/h applied for 7-day wear
Drug: Buprenorphine transdermal patch
Buprenorphine transdermal patch 20 mcg/h applied for 7-day wear

Detailed Description:
Buprenorphine is a synthetic opioid analgesic with over 25 years of international clinical experience indicating it to be safe and effective in a variety of therapeutic situations for the relief of moderate to severe pain. Transdermal systems may offer advantages over currently indicated oral products including ease and convenience of use, improved compliance, possible reduction in patient care, and prolonged and consistent delivery of drug.

Criteria

Inclusion Criteria:
