introduction: association between single-nucleotide polymorphisms (snps) in mu opioid receptor gene and drug addiction has been shown in various studies. here, we have evaluated the existence of polymorphisms in exon 3 of this gene in iranian population and investigated the possible association between these mutations and opioid addiction.  methods: 79 opioid-dependent subjects (55 males, 24 fe...

Throughout the long history of opioid drug use by humans, it has been known that opioids are powerful analgesics, but they can cause addiction. It has also been observed, and is now substantiated by multiple reports and studies, that during opioid treatment of severe and short-term pain, addiction arises only rarely. However, when opioids are extended to patients with chronic pain, and therapeu...

Addiction to opioid analgesics is an important and yet underinvestigated clinical issue, which has substantial implications in opioid therapy for chronic pain management. Problematic opioid use, including compulsive opioid seeking and addiction, arises in some fraction of opioid-treated chronic pain patients. The connection between chronic pain and opioid addiction is a complex interplay betwee...

conclusions a modified tool to assess methadone treatment response serves to identify patients at high-risk for relapse at a minimal cost, as well as evaluate the relevant physical and psycho-social domains affecting opioid-dependent patients. the great will serve as a useful adjunct to regular clinical assessments, allowing clinicians and researchers to properly assess opioid addiction patient...

Public health authorities have described, with growing alarm, an unprecedented increase in morbidity and mortality associated with use of opioid pain relievers (OPRs). Efforts to address the opioid crisis have focused mainly on reducing nonmedical OPR use. Too often overlooked, however, is the need for preventing and treating opioid addiction, which occurs in both medical and nonmedical OPR use...

The Drug Addiction Treatment Act of 2000 (DATA 2000) was established to create a new paradigm for medication-assisted treatment of persons with opiate addiction in the United States. Before enactment of DATA 2000, the use of opioid medications to treat patients with opioid addiction was permissible only in federally approved treatment programs, ie, "methadone clinics." The only medications perm...

Non-coding RNAs (ncRNAs), especially microRNAs, are reported to be involved in a variety of biological processes, including several processes related to drug addiction. It has been suggested that the biological functions of opioids, one typical type of addictive drugs, are regulated by ncRNAs. In the current review, we examine a variety of mechanisms through which ncRNAs could regulate μ-opioid...

to evaluate the effectiveness of a relapse prevention cognitive-behavioral model, based on marlatt treatment approach, in opioid-dependent patients participating in the methadone maintenance treatment (mmt) in iran.the study consisted of 92 individuals treated with methadone in iranian national center of addiction studies (incas). participants were randomized into two groups: educational interv...

Opioid addiction has affected different population groups and socioeconomic classes in the United States at different times. Society's response has changed along with changes in the groups or classes most affected, shifts in social and political attitudes toward opioid addiction, and the accumulation of more and better information about its causes and treatments (Musto 1999). The consensus pane...

Opioids have proven very useful for treatment of acute pain and cancer pain, and in the developed countries opioids are increasingly used for treatment of chronic non-malignant pain patients as well. This literature review aims at giving an overview of definitions, mechanisms, diagnostic criteria, incidence and prevalence of addiction in opioid treated pain patients, screening tools for assessi...
