Study Background
UH3-Pregabalin Plus Lofexidine for the Outpatient Treatment of Opioid Withdrawal
Opioid use disorder can be extremely difficult to overcome due to a variety of factors, including severe withdrawal symptoms. In this clinical research study, we are investigating a combination of medications (lofexidine and pregabalin) to treat opioid withdrawal.
Findings from this study will determine whether new approaches to treating withdrawal will improve our ability to use extended-release naltrexone (Vivitrol) as a relapse-prevention medication. If you are currently dependent on opioids and are potentially interested in extended-release naltrexone to prevent relapse, you may be eligible to participate.
