OBJECTIVE To provide an overview of treatment options for opioid-dependent patients. METHOD We screened all published studies on the treatment of opioid dependence, with a special focus on systematic literature reviews, formal metaanalyses, and recent trials. RESULTS Both clinical experience and neurobiological evidence indicate that opioid dependence is a chronic relapsing disorder. Treatm...

Opioid addiction is no longer a primarily urban problem. As dependence on heroin and prescription pain relievers has become a significant issue in rural areas, the need for effective treatment of opioid-dependent pregnant women and their neonates has grown accordingly. In addition to the adverse perinatal outcomes associated with opioid addiction in pregnant women, the high costs of caring for ...

BACKGROUND Polymorphisms in the μ-, δ- and κ-opioid receptor genes (OPRM1, OPRD1 and OPRK1) have been reported to be associated with substance (alcohol or drug) dependence. The influence of an individual gene on a disease trait should be more evident when analyzed in the context of gene-gene interactions. Thus, we assessed the joint effect of variants in these three opioid receptor genes on alc...

OBJECTIVE To document the development of unique opioid-dependence treatment in remote communities that combines First Nations healing strategies and substitution therapy with buprenorphine-naloxone. DESIGN Quantitative measurements of community wellness and response to community-based opioid-dependence treatment. SETTING Remote First Nations community in northwestern Ontario. PARTICIPANTS...

Previous studies from our laboratory and others have implicated a critical role of Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) in opioid tolerance and dependence. Translational research targeting the CaMKII pathway is challenging, if not impossible, because of a lack of selective inhibitors. We discovered in a preliminary study that haloperidol, a butyrophenone antipsychotic drug, in...

Given the increase of opioid dependence and opioid-related morbidity and mortality, improving treatment options for individuals with opioid dependence warrants increased attention. This article provides a concise review of work in this area. Remission from opioid dependence can be very difficult to sustain, particularly in the absence of opioid replacement or opioid antagonist therapy. For thos...

Recently it has been revealed that some agents that are not able to interact with opioid receptors play an important role in regulating the pharmacological actions of opioids. Especially, some of them show biphasic modulation on opioid functions, which enhance opioid analgesia, but inhibit tolerance to and substance dependence on opioids. We would like to call these agents which do not interact...

BACKGROUND While nonmedical use of opioids and psychiatric disorders are prevalent in the population, little is known about the temporal ordering between nonmedical opioid use and dependence and psychiatric disorders. METHOD Data were gathered in a face-to-face survey of the United States conducted in the 2001-2002 (NESARC wave 1). Participants were household and group quarters residents aged...

BACKGROUND Personality traits may form a part of the aetiology of opioid dependence. For instance, opioid dependence may result from self-medication in emotionally unstable individuals, or from experimenting with drugs in sensation seekers. The five factor model (FFM) has obtained a central position in contemporary personality trait theory. The five factors are: Neuroticism, Extraversion, Openn...
