Phase 4

Completed

• Conditions: Opioid Dependence
• Interventions: Drug: Zubsolv sublingual tablets; Drug: Suboxone Sublingual Film

• Registration Number: NCT02038790
• Lead Sponsor: Indivior Inc.

Brief Summary

The primary objective of this study is to compare overall patient preference for either Suboxone® sublingual film 8/2 or Zubsolv® sublingual tablets 5.7/1.4. Suboxone sublingual film 8/2 contains 8mg buprenorphine and 2mg naloxone. Zubsolv sublingual tablets contain 5.7 mg buprenorphine and 1.4 mg naloxone.
