BACKGROUND: We previously reported that a methanol extract of Glycyrrhizae radix (MEGR) blocked methamphetamine-induced locomotor sensitization and conditioned place preference in rats. In the present study, the effects of MEGR on repeated nicotine-induced locomotor sensitization and enhanced extracellular dopamine (DA) release in the nucleus accumbens (Nacc) were evaluated. METHODS: Male Sprague-Dawley rats received repeated administrations of nicotine (0.4 mg/kg, subcutaneous) or saline twice a day for 7 d and were challenged with nicotine 4 d after the last daily dosing...

We assessed the efficacy of pexacerfont, a CRF1 antagonist, for the treatment of withdrawal symptoms. In this randomized, double-blind, placebo-controlled clinical trial, male patients with amphetamine or opioid dependence, on the basis of the Diagnostic and Statistical Manual of Mental Disorders, 4th ed., Text Revision (DSM-IV-TR), in the age range 18-55 years, received either pexacerfont or placebo (300, 200, and 100 mg/day in the first, second, and third week, respectively). No antidepressants, behavioral interventions, or substitution therapy were administered...

PURPOSE: As the use of recreational drugs increases, the likelihood of an anesthesiologist perioperatively encountering patients using or addicted to these drugs will also increase. PRINCIPAL FINDINGS: Addicted patients may present for anesthetic care in a variety of circumstances in everyday elective surgeries or in acute or life-saving situations, such as emergency Cesarean delivery or trauma surgery. Therefore, it is important for anesthesiologists to know about the most common illicit drugs being used, their clinical presentation and side effects, and the anesthetic options that are beneficial or detrimental to these patients...

Methamphetamine addiction is mimicked in rats that self-administer the drug. However, these self-administration (SA) models do not include adverse consequences that are necessary to reach a diagnosis of addiction in humans. Herein, we measured genome-wide transcriptional consequences of methamphetamine SA and footshocks in the rat brain. We trained rats to self-administer methamphetamine for 20 days. Thereafter, lever-presses for methamphetamine were punished by mild footshocks for 5 days. Response-contingent punishment significantly reduced methamphetamine taking in some rats (shock-sensitive, SS) but not in others (shock-resistant, SR)...

This chapter summarizes recent developments in preclinical and clinical research on Chinese herbal medicines and their neurochemical mechanism of action for the treatment of drug addiction. We searched Chinese and English scientific literature and selected several kinds of Chinese herbal medicines that have beneficial effects on drug addiction. Ginseng (Renshen) may be clinically useful for the prevention of opioid abuse and dependence. Rhizoma Corydalis (Yanhusuo) may be used to prevent relapse to chronic drug dependence...

Toxic leukoencephalopathy represents a process of structural alteration of the white matter. It is caused by substance abuse including drugs such as heroin, cocaine, toluene and ethanol. We reported the clinical, radiological and autopsy findings of a rare case of toxic leukoencephalopathy following chronic methamphetamine (MA) usage. A 34-year-old man with a 3-year history of MA abuse experienced progressive sluggish state, limb weakness, inability to stand and eating disorders, followed by rapid progression to coma and death...

BACKGROUND: Depression symptoms is highly comorbid with methamphetamine (METH) dependence. Except for the role in the pathophysiology of depression symptoms, brain-derived neurotrophic factor (BDNF) is also involved in the METH dependence. The present study aims to explore whether BDNF plays a role in the development of depression symptoms during METH withdrawal. METHODS: We recruited 179 patients with METH dependence who were followed up for two weeks. Ultimately, 131 (73...

Accumulating evidence has suggested that repeated treatment with methamphetamine (MA) resulted in cognitive impairments. Importantly, we show that selective upregulation of protein kinase Cδ (PKCδ) in the prefrontal cortex (PFC) of wild-type mice persisted for 28 days post withdrawal of MA. On day 28, the MA-induced increase in phospho-PKCδ expression and decrease in phospho-ERK1/2 expression were significantly attenuated by both the Src inhibitor PP2 and the dopamine D1 receptor antagonist SCH 23390. However, neither protein kinase A inhibitor H89 nor calmodulin-dependent protein kinase II inhibitor KN93 attenuated MA-induced alterations in phospho-PKCδ expression and phospho-ERK1/2 expression...

BACKGROUND: We sought to test the effectiveness of methadone and buprenorphine in the treatment of methamphetamine withdrawal craving over a 17-day treatment period. METHODS: Patients were randomized into one of two groups. The study sample comprised 40 male subjects dependent on methamphetamine who met criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, for methamphetamine dependence and withdrawal and were seeking treatment. Furthermore, they should have a history of daily methamphetamine use for at least 6 months and should have discontinued their use just before starting the protocol...

RATIONALE: Drug addiction can be described as aberrant allocation of effort toward acquiring drug, despite associated costs. It is unclear if this behavioral pattern results from an overvaluation of reward or to an altered sensitivity to costs. OBJECTIVE: Present experiments assessed reward sensitivity and effortful choice in rats following 1 week of withdrawal from methamphetamine (mAMPH). METHODS: Rats were treated with either saline or an escalating dose mAMPH regimen, then tested after a week without the drug...

Over the past several years, the number of first-time users of methamphetamine considerably increased within the Free State of Saxony. This number also, and especially, includes women of child-bearing age and young mothers. A supportive intervention aimed at reducing the effects of drug abuse should begin in a timely way - during pregnancy at latest, but better before it. To develop an optimal care protocol for both the mother and her child, more knowledge regarding the personal conditions of the women as well as the specific features of later child development after prenatal methamphetamine exposure (PME) is vital...

Objective: This study was designed to examine the effect of environmental enrichment during methamphetamine (METH) dependency and withdrawal on methamphetamine-induced spatial learning and memory deficits and obsessive-compulsive behavior. Method: Adult male Wistar rats (200 ± 10 g) chronically received bi-daily doses of METH (2 mg/kg, sc, with 12 hours intervals) for 14 days. Rats reared in standard (SE) or enriched environment (EE) during the development of dependence on METH and withdrawal. Then, they were tested for spatial learning and memory (the water maze), and obsessive-compulsive behavior as grooming behavior in METH-withdrawn rats...

The increasing abuse of the street drug crystal meth (methamphetamine) in many countries worldwide has resulted in a growing demand to treat patients who have acquired a methamphetamine-related disorder. The results of a systematic literature search which led to the consensus-based recommendations by the Working Group of the German Agency for Quality in Medicine (Ärztliches Zentrum für Qualität in der Medizin - ÄZQ) are presented. Pharmacological treatments were reviewed in 58 out of the 103 publications included...

Anxiety is often a core element of withdrawal symptoms; however, risk factors associated with anxiety symptoms during the early stage of withdrawal in methamphetamine (METH) users are not well understood. Two hundred ten METH-dependent subjects who had been abstinent for 1 to 7 days were recruited. We used a set of self-administrative questionnaires eliciting information on sociodemographics, detailed drug use history and anxiety. Beck Anxiety Inventory (BAI) was used to measure anxiety symptoms. METH users had a mean BAI score of 6...

RATIONALE: Both l- and d-methamphetamine (l- and d-MA) are more potent to release norpepinephrine (NE) than dopamine, and the selectivity is greater for l-MA than d-MA. Little is known of the in vivo pharmacology of l-MA. OBJECTIVE: This study compared the effects of l-MA and d-MA in assays of nociception, behavioral disruption, and impulsivity. METHODS: Antinociceptive effects of d- and l-MA were examined in two pain assays: the warm water tail withdrawal test for acute nociception and the von Frey test in complete Freund's adjuvant (CFA)-treated rats for chronic inflammatory pain...

Methamphetamine (METH) addicts lose control over drug consumption despite suffering multiple adverse medicolegal consequences. To mimic the negative events associated with drug addiction in humans, we recently introduced a rat model of self-administration (SA) with response-contingent punishment on METH intake. These procedures allowed us to distinguish between two addiction-like phenotypes in rats, those that sustained METH taking despite negative consequences (shock-resistant, SR) and rats that significantly reduced their METH intake (shock-sensitive, SS)...

Different methamphetamine use patterns in human subjects may contribute to inconsistent findings regarding the effects of methamphetamine abuse on brain and behavior. The present study investigated whether human-derived chronic and binge methamphetamine use patterns have differential effects on reward and neurochemistry in mice. Brain reward function in mice was evaluated during acute/prolonged withdrawal, and in response to methamphetamine challenge using the intracranial self-stimulation procedure. Brain dopaminergic, serotonergic and glutamatergic neurochemistry was determined with high-performance liquid chromatography...
