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.

Buprenorphine is a medication used to treat opioid addiction, but individuals who use this drug are at risk of abusing it. A buprenorphine and naloxone combination may reduce the likelihoo...
The purpose of this study is to evaluate varying doses of buprenorphine for opioid dependence and cocaine abuse.

This is a residential study that looks at the effects of buprenorphine in persons who abuse but are not dependent on opioids. Animal studies show that very high doses of buprenorphine pro...
The association with opioid-abusing individuals or even the perception of opioid abuse by peers are risk factors for the initiation and escalation of abuse. Similarly, we demonstrated that morphine-tr...
Buprenorphine/samidorphan combination (BUP/SAM) is an opioid system modulator being investigated as adjunctive treatment for major depressive disorder. BUP/SAM is a fixed-dose combination of buprenorp...
There are sex differences in buprenorphine/naloxone clinical trials for opioid use. While women have fewer opioid-positive urine samples, relative to men, a significant decrease in opioid-positive sam...
Opioid use disorders are a major medical and public health concern. Buprenorphine is approved for the treatment of opioid use disorders; however, a shortage of physicians prescribing buprenorphine is ...
Opioid use disorder (OUD) is a critical concern among US veterans. The Veterans Health Administration (VHA) recommends buprenorphine as a first-line treatment for OUD; however, only 35% of veterans wi...
A derivative of the opioid alkaloid THEBAINE that is a more potent and longer lasting analgesic than MORPHINE. It appears to act as a partial agonist at mu and kappa opioid receptors and as an antagonist at delta receptors. The lack of delta-agonist activity has been suggested to account for the observation that buprenorphine tolerance may not develop with chronic use.
A pharmaceutical preparation that combines buprenorphine, an OPIOID ANALGESIC with naloxone, a NARCOTIC ANTAGONIST to reduce the potential for NARCOTIC DEPENDENCE in the treatment of pain. It may also be used for OPIATE SUBSTITUTION THERAPY.
A synthetic opioid that is used as the hydrochloride. It is an opioid analgesic that is primarily a mu-opioid agonist. It has actions and uses similar to those of MORPHINE. It also has a depressant action on the cough center and may be given to control intractable cough associated with terminal lung cancer. Methadone is also used as part of the treatment of dependence on opioid drugs, although prolonged use of methadone itself may result in dependence. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1082-3)
An opioid analgesic made from MORPHINE and used mainly as an analgesic. It has a shorter duration of action than morphine.
A class of opioid receptors recognized by its pharmacological profile. Mu opioid receptors bind, in decreasing order of affinity, endorphins, dynorphins, met-enkephalin, and leu-enkephalin. They have also been shown to be molecular receptors for morphine.
