Conditions opioid abuse, opioid dependence
Treatments buprenorphine, morphine
Phase phase 1/phase 2
Sponsor Johns Hopkins University
Collaborator National Institute on Drug Abuse (NIDA)
Start date July 2010
End date March 2012
Trial size 100 participants
Trial identifier NCT01136356, DPMC, NIDA-08045-9, R01DA008045


Buprenorphine is an approved medication for the treatment of opioid dependence. It is typically administered once daily as a sublingual tablet combined with naloxone (i.e., Suboxone). Evidence suggests buprenorphine produces relatively low levels of physical dependence. In addition, some research suggests there is relatively little withdrawal following cessation of chronically administered buprenorphine. This study will examine the spontaneous withdrawal associated with abrupt cessation of buprenorphine compared to morphine in opioid dependent individuals. This study will assess the characteristics and time course of withdrawal using subject-rated and observer-rated measures of opioid withdrawal. Physiologic measures and psychomotor performance will be collected during chronic opioid administration and during placebo administration (i.e., during spontaneous withdrawal). Particular attention will be paid to the differences (if any) in sleep disturbances and withdrawal associated hyperalgesia.
