Substance-related and addictive disorders are chronic relapsing conditions that substantially impact public health. Effective treatments for these disorders require addressing substance use/dependence comprehensively as well as other associated comorbidities. Comprehensive addressing of substance use in a medical setting involves screening for substance use, addressing substance use directly wi...

The development of alcohol dependence is the result of a combination of various factors. Psychosocial and psychiatric conditions, together with functional alterations of the brain or genetic traits, contribute to the development of problems related to alcohol use or alcohol dependence. Clinical studies using neuroimaging techniques (PET, fMRI) and preclinical studies using different animal mode...

OBJECTIVE To review the evidence on identifying and managing misuse of and dependence on opioids among primary care patients with chronic pain. QUALITY OF EVIDENCE MEDLINE was searched using such terms as "opioid misuse" and "addiction." The few studies on the prevalence of opioid dependence in primary care populations were based on retrospective chart reviews (level II evidence). Most recomm...

BACKGROUND Large interindividual differences in clinical responses to opioids and the variable susceptibility to abuse of this class of drugs make their use problematic. We lack a full understanding of the factors responsible for these differences. Dietary factors including methyl donor content have been noted to alter multiple physiological and behavioral characteristics of laboratory animals....

The innate immune system modulates opioid-induced effects within the central nervous system and one target that has received considerable attention is the toll-like receptor 4 (TLR4). Here, we examined the contribution of TLR4 in the development of morphine tolerance, hyperalgesia, and physical dependence in two inbred mouse strains: C3H/HeJ mice which have a dominant negative point mutation in...

This article reviews the use of opioid antagonists in the pharmacologic treatment of alcohol dependence. The rationale for using the opioid antagonists naltrexone and nalmefene to prevent relapse in alcohol-dependent subjects is discussed by reviewing past and current clinical trials. The role of psychotherapies, particularly coping skills therapy, in combination with opioid antagonists is high...

Abstract Background:In general, parental substance abuse is associated with children's emotional and behavioral problems. This study only investigated the internalizing problems (depression, anxiety and physical complains) in children of opioid or heroin-dependent parents in comparison with non-opioid dependent parents in order to determine the effects of drug dependency after exclu...

Opioid agonists are the most effective treatment for pain, but their use is limited by side effects, tolerance and fears of addiction and dependence. A major goal of opioid research is to develop agonists that have high analgesic efficacy and a low profile for side effects, tolerance, addiction and dependence. Unfortunately, there is a serious lack of experimental data comparing the degree to w...
