Preference for Subutex® (Buprenorphine) Versus Suboxone® (Buprenorphine/Naloxone) in Opioid Dependent Patients on Subutex® (Study P05094)(COMPLETED)
This study is designed to determine if opioid dependent subjects who are already receiving Subutex® prefer the Suboxone® tablet over the Subutex® tablet after switching from Subutex® to Suboxone®. Subjects who are selected to participate in this study will continue their prescribed dose of Subutex® (buprenorphine 2 to 16 mg daily) for the first two days of the study (Day 1 and Day 2) then switch to and receive an equivalent dose of Suboxone® (buprenorphine 2 to 16 mg daily) for the last 3 days of the study (Day 3, Day 4 and Day 5). The Day 5 Visit will be the subject's last study visit. Upon completing the study, subjects will continue their pre-study prescribed dosage of Subutex®.
