OBJECTIVE: To conduct the first systematic literature review of clinical trials of N-acetylcysteine (NAC) for the treatment of substance abuse disorders and addictive behaviors. METHODS: A search of the MEDLINE, Embase and PsycINFO databases was conducted. The inclusion criteria for the review were clinical trials that used NAC in the treatment of a disorder related to substance use and/or addictive behaviors, limited to texts in English, Spanish, or French. The selected studies were evaluated with respect to type of trial, sample size, diagnostic input, intervention, length of follow-up, outcome variables, and results...

The aversive effect of nicotine withdrawal is greater in female versus male rats, and we postulate that this sex difference is mediated in the nucleus accumbens (NAc). Nicotine withdrawal induces decreases in NAc dopamine and increases in acetylcholine (ACh) levels in male rats. To our knowledge, these neurochemical markers of nicotine withdrawal have not been compared in female versus male rats. Given the role of amino acids in modulating NAc dopaminergic and cholinergic transmission, concomitant measures of gamma-aminobutyric acid (GABA) and glutamate levels were also compared across sex...

Internet gaming disorder represents a growing health issue. Core symptoms include unsuccessful attempts to control the addictive patterns of behavior and continued use despite negative consequences indicating a loss of regulatory control. Previous studies revealed brain structural deficits in prefrontal regions subserving regulatory control in individuals with excessive Internet use. However, because of the cross-sectional nature of these studies, it remains unknown whether the observed brain structural deficits preceded the onset of excessive Internet use...

UNLABELLED: Dependence is a hallmark feature of opiate addiction and is defined by the emergence of somatic and affective withdrawal signs. The nucleus accumbens (NAc) integrates dopaminergic and glutamatergic inputs to mediate rewarding and aversive properties of opiates. Evidence suggests that AMPA glutamate-receptor-dependent synaptic plasticity within the NAc underlies aspects of addiction. However, the degree to which NAc AMPA receptors (AMPARs) contribute to somatic and affective signs of opiate withdrawal is not fully understood...

Jennifer Kaufling, Gary Aston-Jones
UNLABELLED: Protracted opiate withdrawal is accompanied by altered responsiveness of midbrain dopaminergic (DA) neurons, including a loss of DA cell response to morphine, and by behavioral alterations, including affective disorders. GABAergic neurons in the tail of the ventral tegmental area (tVTA), also called the rostromedial tegmental nucleus, are important for behavioral responses to opiates. We investigated the tVTA-VTA circuit in rats after chronic morphine exposure to determine whether tVTA neurons participate in the loss of opiate-induced disinhibition of VTA DA neurons observed during protracted withdrawal...

Michael T Bowen, Inga D Neumann
The neuropeptide oxytocin is released both into the blood and within the brain in response to reproductive stimuli, such as birth, suckling and sex, but also in response to social interaction and stressors. Substance use disorders, or addictions, are chronic, relapsing brain disorders and are one of the major causes of global burden of disease. Unfortunately, current treatment options for substance use disorders are extremely limited and a treatment breakthrough is sorely needed. There is mounting preclinical evidence that targeting the brain oxytocin system may provide that breakthrough...

REVIEW
Kendall D Jeynes, E Leigh Gibson
BACKGROUND: Nutrition is a prerequisite for health; yet, there is no special nutritional assessment or guidance for drug and alcohol dependent individuals, despite the fact that their food consumption is often very limited, risking malnutrition. Further, the premise is examined that malnutrition may promote drug seeking and impede recovery from substance use disorders (SUD). METHOD: A narrative review addressed the relationship between substance use disorders and nutrition, including evidence for malnutrition, as well as their impact on metabolism and appetite regulation...

Li-Min Mao, Qiang Wang
Protein phosphorylation is an important posttranslational modification of group I metabotropic glutamate receptors (mGluR1 and mGluR5 subtypes) which are widely distributed throughout the mammalian brain. Several common protein kinases are involved in this type of modification, including protein kinase A, protein kinase C, and extracellular signal-regulated kinase. Through constitutive and activity-dependent phosphorylation of mGluR1/5 at specific residues, protein kinases regulate trafficking, subcellular/subsynaptic distribution, and function of modified receptors...

Drug addiction treatment medications available nowadays are limited in both efficacy and number. The increased understanding of drug addiction circuitries leads the scientific community to look for better molecules and targets for detoxification and relapse prevention. This review focus on known targets (e.g., metabotropic glutamate receptor 5 and GABAB receptor) and on novel potential treatment acting on oxytocin system, which interacts with diverse neurotransmitters, has proved successful in both preclinical and clinical studies on ethanol, cocaine and methamphetamine...

Opioid drugs, including prescription as well as heroin, have come to the national spotlight due to the unprecedented rate of overdose and addiction. The Centers for Disease Control and Prevention (CDC) has termed this problem as an "epidemic" that has reached record numbers of deaths in 2014. Approximately half of these deaths are the result from prescribed opioids. Also on the rise are the numbers of individuals who are diagnosed with chronic pain and are treated with opioids, methadone and buprenorphine. Individuals currently taking opioids for chronic pain confound the treatment of acute pain after traumatic injury...

R Bellmann, M Joannidis
Psychotropic drugs are medications that are indicated for treatment of psychiatric disorders. Attempted suicide is the major reason for intoxication but inadvertent overdosing may also occur. Other psychotropic agents are taken because of their stimulating and hallucinogenic effects and many have a high addictive potential. Poisoning is usually due to accidental overdosing. For treatment of benzodiazepine and opioid intoxication, flumazenil and naloxone, respectively, are used as specific antagonists. For intoxication by tricyclic antidepressants, sodium bicarbonate is the treatment of choice...

Genetic factors involved in the susceptibility to drug addiction still remain largely unknown. MiRNAs seem to play key roles in the drug-induced plasticity of the brain that likely drives the emergence of addiction. In this work we explored the role of miRNAs in drug addiction. With this aim, we selected 62 SNPs located in the 3'UTR of target genes that are predicted to alter the binding of miRNA molecules and performed a case-control association study in a Spanish sample of 735 cases (mainly cocaine-dependent subjects with multiple drug dependencies) and 739 controls...

We are faced with a worldwide opiate/opioid epidemic that is devastating. According to the Centers for Disease Control and Prevention (CDC), at least 127 people, young and old, are dying every day in America due to narcotic overdose. The Food and Drug Administration (FDA) has approved Medication-Assisted Treatments (MATs) for opiate/opioids as well as alcohol and nicotine. The mechanism of action of most MATS favors either blocking of dopaminergic function or a form of Opiate Substitution Therapy (OST). These treatment options are adequate for short-term treatment of the symptoms of addiction and harm reduction but fail long-term to deal with the cause or lead to recovery...

REVIEW
G Aleph Prieto
Dopamine D3 receptors (D3R) modulate neuronal activity in several brain regions including cortex, striatum, cerebellum, and hippocampus. A growing body of evidence suggests that aberrant D3R signaling contributes to multiple brain diseases, such as Parkinson's disease, essential tremor, schizophrenia, and addiction. In line with these findings, D3R has emerged as a potential target in the treatment of neurological disorders. However, the mechanisms underlying neuronal D3R signaling are poorly understood, either in healthy or diseased brain...

BACKGROUND AND AIM: Cryptomarkets-on-line, anonymous market-places for illicit goods and services that specialize mainly in drugs-account for a small but rapidly growing share of the illicit drug market in many countries. Policy responses so far are based generally on the assumption that their rise will only increase drug harms. In this contribution for debate, we question this assumption. METHODS: We provide a narrative review of the emerging literature connected to drug cryptomarkets...

REVIEW
Manoranjan S D'Souza, Athina Markou
Psychostimulant drugs have powerful reinforcing and hedonic properties and are frequently abused. Cessation of psychostimulant administration results in a withdrawal syndrome characterized by anhedonia (i.e., an inability to experience pleasure). In humans, psychostimulant withdrawal-induced anhedonia can be debilitating and has been hypothesized to play an important role in relapse to drug use. Hence, understanding the neural substrates involved in psychostimulant withdrawal-induced anhedonia is essential...

BACKGROUND: There is an expanding field of research investigating the benefits of medicines with multiple mechanisms of action across neurological disorders. N-acetylcysteine (NAC), widely known as an antidote to acetaminophen overdose, is now emerging as treatment of vascular and nonvascular neurological disorders. NAC as a precursor to the antioxidant glutathione modulates glutamatergic, neurotrophic, and inflammatory pathways. AIM AND DISCUSSION: Most NAC studies up to date have been carried out in animal models of various neurological disorders with only a few studies completed in humans...

The burgeoning area of the application of nutritional and alternative medicine technologies in integrated medicine and psychiatry has taken root in the treatment of addictive disorders. Nutritional supplements spanning a wide range may be therapeutic in treating both deficiencies or insufficiencies as well as an adjunct to pharmacological interventions. Nutritional supplements that are commonly utilized in the treatment of addiction disorders and corresponding co-morbid psychiatric disorders or symptoms include l-methylfolate, vitamin D, inositol, l-tryptophan, omega 3 fatty acids, s-adenosyl methionine (SAM-E), N-acetylcysteine (NAC), melatonin, rhodiola rosea, valerian, chromium, creatine, and hypericum...

Benzydamine (BZY) is a non-steroidal anti-inflammatory drug used for the topical treatment of inflammations of the oral and vaginal mucosae. Virtually nothing is known about the central pharmacological actions of BZY. Yet there are reports of voluntary systemic overdosage of BZY in drug addicts, resulting in a euphoric, hallucinatory state. In the present study, we investigated the reinforcing properties of BZY in a rat self-administration paradigm. We found that BZY has a powerful reinforcing effect and that this effect is greatly facilitated in animals that already had substance experience, having previously self-administered heroin and cocaine, indicating cross sensitization between BZY and other common drugs of abuse...
