Since the 1990s, the use of prescription opioids has largely spread, which has brought a real progress in the treatment of pain. The long-term use of prescription opioid is sometimes required, and may lead to pharmacological tolerance and withdrawal symptoms, i.e. pharmacological dependence on prescription opioids. Occasionally, this may also lead to misuse of prescription opioids (MPO). MPO preferentially occurs in vulnerable individuals, i.e., those with a young age, history of other addictive or psychiatric disorders, especially anxious and depressive disorders...

Cocaine addiction remains a serious challenge for clinical and medical research because there is no effective pharmacological treatment. l-THP, a natural product isolated from Corydalis yanhusuo W.T. Wang, is one of the most frequently used traditional herbs to treat drug addiction in China. Our laboratory first reported that its demethylated metabolites l-ICP, l-CD, and l-CP had high affinity at dopamine D1, D2, and D5 receptors. Here we report the chemical synthesis of these metabolites and other derivatives and their binding affinities at dopamine receptors...

The aim of this paper is to extensively review the current literature available on N-acetylcysteine (NAC) treatment for cocaine dependence (clinical and experimental studies). We screened all articles published before February 2016 reporting on the use of NAC as a pharmacological intervention for cocaine dependence or discussed its potential as a therapeutic approach for cocaine dependence. We described our results qualitatively. 21 studies matched our search criteria: 6 clinical trials and 15 animal studies...

Activated B-cell-like (ABC) and germinal center B-cell-like (GCB) diffuse large B-cell lymphoma (DLBCL) represent the two major molecular DLBCL subtypes. They are characterized by differences in clinical course and by divergent addiction to oncogenic pathways. To determine activity of novel compounds in these two subtypes, we conducted an unbiased pharmacologic in vitro screen. The phosphatidylinositol-3-kinase (PI3K) alpha/delta (PI3Kα/δ) inhibitor AZD8835 showed marked potency in ABC DLBCL models, whereas the protein kinase B (AKT) inhibitor AZD5363 induced apoptosis in PTEN-deficient DLBCLs irrespective of their molecular subtype...

Pharmacogenetic studies have identified the non-synonymous single nucleotide polymorphism (A118G) in the human mu opioid receptor (MOR) gene (OPRM1) as a critical genetic variant capable of altering the efficacy of opioid therapeutics. To date few studies have explored the potential impact of the OPRM1 A118G polymorphism on the pharmacological effects of buprenorphine (BPN), a potent MOR partial agonist and kappa opioid receptor antagonist, which is approved by the FDA for the treatment of opioid addiction and chronic pain...

Opioid addiction during pregnancy presents a treatment challenge to clinicians and women alike. Untreated addiction can lead to poor maternal and fetal health outcomes. Medication-assisted treatment is the standard of care, and methadone is the current drug of choice for treatment. Emerging evidence also supports the use of buprenorphine during pregnancy. Both methadone and buprenorphine have risks and benefits that should be explored before initiating treatment. Clinicians who work in obstetrics and in addiction treatment can collaborate and coordinate treatment to ensure optimal maternal and fetal outcomes...

Alcoholism is a complex brain disease characterized by three distinct stages of the addiction cycle that manifest as neuroadaptive changes in the brain. One such stage of the addiction cycle is alcohol withdrawal and the negative affective states that promote drinking and maintain addiction. Repeated alcohol use, genetic predisposition to alcoholism and anxiety, and alcohol exposure during crucial developmental periods all contribute to the development of alcohol-induced withdrawal and negative affective symptoms...

The United States is facing a major crisis with the current opioid epidemic. Tens of thousands of individuals are dying each year due to abuse and misuse of heroin and prescription opiate drugs. Nurses play an integral role in these aspects of health care and offer solutions by providing education; preventive measures; treatments, including medication-assisted treatments (MATs); and ongoing recovery options for individuals with opioid use disorders. Nurses provide education, issue prescriptions and dispense medications, and provide overall physical and mental health care to patients struggling with this "disease of the brain," and with the signing of the Comprehensive Addiction and Recovery Act, advanced practice RNs will soon be able to include MATs related to buprenorphine as part of their treatment plan...

Methamphetamine (METH) is a widely abused psychostimulant displaying potent addictive and neurotoxic properties. METH induces neurotoxicity of dopaminergic terminals and striatal neurons in the striatum. Despite much information on neurotransmitters, the role of neuropeptides is poorly understood. In this study, we investigated the role of the neuropeptide neurotensin on the METH-induced apoptosis of some striatal neurons in mice. We observed that a single injection of METH (30 mg/kg, ip) induced the loss of approximately 15% of striatal neurons...

: A novel G-protein coupled receptor, trace amine-associated receptor 1 (TAAR1), has been shown to be a promising target to prevent stimulant relapse. Our recent studies showed that systemic administration of TAAR1 agonists decreased abuse-related behaviors of cocaine. However, the role of TAAR1 in specific subregions of the reward system in drug addiction is unknown. Here, using a local pharmacological activation method, we assessed the role of TAAR1 within the subregions of the mesocorticolimbic system: that is, the VTA, the prelimbic cortex (PrL), and infralimbic cortex of medial prefrontal cortex, the core and shell of NAc, BLA, and CeA, on cue- and drug-induced cocaine-seeking in the rat cocaine reinstatement model...

Psychostimulant addiction is an important, relapsing condition for which there is no effective pharmacological treatment. Countering this problem requires an understanding of the specific risk factors that predispose individuals to initial misuse of these drugs. Healthy individuals display marked individual differences in emotional, behavioral and brain responses to low and moderate doses of stimulant drugs. These between-person differences have been most often studied using personality measures of sensation seeking...

Tetrahydroprotoberberines (THPB) have a high affinity for dopamine (DA) D1 and D2 receptors and may provide a novel treatment for drug addiction. We assessed the effects of the THPB d-govadine on the acquisition, expression, extinction and reinstatement of d-amphetamine-(1.5mg/kg, i.p.) induced conditioned place preference (CPP). Furthermore, the effects of d-govadine on conditioned association between contextual stimuli and a natural reward were examined using food-induced CPP. In separate experiments, rats received d-govadine (0, 0...

Although extensive research has focused on understanding the neurobiological mechanisms underlying alcohol addiction, pharmacological treatments for alcohol use disorders are very limited and not always effective. This constraint has encouraged the search for novel pharmacological targets for alcoholism therapy. Sigma receptors were shown to mediate some of the properties of cocaine and amphetamine, which was attributed to the direct binding of psychostimulants to these receptors. More recently, the role of sigma receptors in the rewarding and reinforcing effects of alcohol was also proposed, and it was suggested that their hyperactivity may result in excessive alcohol drinking...

Diazepam is a benzodiazepine receptor agonist with anxiolytic and addictive properties. Although most drugs of abuse increase the level of release of dopamine in the nucleus accumbens, here we show that diazepam not only causes the opposite effect but also prevents amphetamine from enhancing dopamine release. We used 20 min sampling in vivo microdialysis and subsecond fast-scan cyclic voltammetry recordings at carbon-fiber microelectrodes to show that diazepam caused a dose-dependent decrease in the level of tonic and electrically evoked dopamine release in the nucleus accumbens of urethane-anesthetized adult male Swiss mice...

Understanding individual differences in response to social stress and environmental enrichment on brain function and drug abuse may help explain the variability in response to behavioral and pharmacological treatments for drug addiction. In monkeys, social status influences the reinforcing effects of cocaine and the effects of some drugs on cocaine self-administration. In this study, we used male cynomolgus macaques (n=15) living in established social groups to examine the effects of social confrontation on the reinforcing effects of cocaine using a food-drug choice procedure...

BACKGROUND AND OBJECTIVES: There is significant variability in severity of neonatal abstinence syndrome (NAS) due to in utero opioid exposure. Our previous study identified single nucleotide polymorphisms (SNPs) in the prepronociceptin (PNOC) and catechol-O-methyltransferase (COMT) genes that were associated with differences in NAS outcomes. This study looks at the same SNPs in PNOC and COMT in an independent cohort in an attempt to replicate previous findings. METHODS: For the replication cohort, full-term opioid-exposed newborns and their mothers (n = 113 pairs) were studied...
