BACKGROUND Individuals with opioid dependence have cognitive deficits during abuse period in attention, working memory, episodic memory, and executive function. After protracted abstinence consistent cognitive deficit has been found only in executive function. However, few studies have explored cognitive function during first weeks of abstinence. The purpose of this study was to study cognitive...
Over the past few years, advances in the investigation of the neurochemical circuits involved in the development and treatment of alcohol dependence have identified peptides and receptors as potential key targets in the treatment of problems related to alcohol consumption. The endogenous opioid system is modified by alcohol intake in areas of the brain related to reward systems, and differentia...
BACKGROUND Depression with psychomotor agitation (PMA; "agitated depression") is a putative psychiatric phenotype that appears to associate with some forms of substance dependence. However, it is unclear whether such relationships extend across different substances and independent (I-MDE) versus substance-induced (SI-MDE) subtypes of major depressive episodes. METHOD We examined whether lifet...
Chronic pain is commonly treated by prescribing an opioid medication. For those suffering from both chronic pain and substance dependence, barriers to adequate pain management increase. This often causes both disorders to exacerbate one another. Effective treatment may also be hampered by opioid-induced hyperalgesia, tolerance, physical dependence, "chemical coping," and diminished physical and...
BACKGROUND Opioids are psychoactive analgesic drugs prescribed for pain relief and palliative care. Due to their addictive potential, effort and vigilance in controlling prescriptions is needed to avoid misuse and dependence. Despite the effort, the prevalence of opioid use disorder continues to rise. Opioid substitution therapies are commonly used to treat opioid dependence; however, there is ...
BACKGROUND Results of preclinical studies suggest that the GABA(B) receptor agonist baclofen may be useful in treatment of opioid dependence. This study was aimed at assessing the possible efficacy of baclofen for maintenance treatment of opioid dependence. METHODS A total of 40 opioid-dependent patients were detoxified and randomly assigned to receive baclofen (60 mg/day) or placebo in a 12-...
Opioids, amphetamines, and other types of substances have been widely abused around the world. Opioid dependence and tolerance are two distinct phenomena that have been associated with substance abuse issues. The management of its adverse consequences is becoming more challenging. More and more people are treated in Methadone Maintenance Therapy (MMT) program yet the issues are still unresolved...
BACKGROUND Naltrexone is a competitive opioid antagonist and is often used to maintain abstinence in detoxified opioid dependent patients. However, it can precipitate an accelerated withdrawal when ingested by an individual with concurrent opioid use. METHODS We report the case of a 28 year old male with opioid dependence syndrome presenting with chaotic symptoms following ingestion of naltre...
Buprenorphine (Subutex) and buprenorphine/naloxone (Suboxone) received Food and Drug Administration approval in 2002 for the treatment of opioid dependence. Introduction of these drugs expanded the availability of opioid-dependence treatment options to reduce the morbidity and mortality associated with opioid abuse, and buprenorphine has become an increasingly prescribed component of office-bas...
The mechanism of chronic pain is very complicated. Memory, pain, and opioid dependence appear to share common mechanism, including synaptic plasticity, and anatomical structures. A 48-yr-old woman with severe pain caused by bone metastasis of breast cancer received epidural block. After local anesthetics were injected, she had a seizure and then went into cardiac arrest. Following cardiopulmona...
