项目摘要

DESCRIPTION (provided by applicant): Acetylcholine (ACh) is involved in brain reward and learning functions, and perturbations to this neurotransmitter system may contribute to substance abuse disorders. Animal studies have shown the importance of muscarinic ACh receptors in cocaine reinforced- and non-reinforced-responding, and acetylcholinesterase (AChE) inhibitors reduced methamphetamine-seeking behavior in rodents. Consistent with these findings, a recently completed double-blind placebo-controlled study from our group demonstrated that treatment with the AChE inhibitor rivastigmine reduced craving produced by administration of methamphetamine in the laboratory. In this application, we propose a human laboratory research to evaluate the effects of rivastigmine (3 or 6 mg, daily) or huperzine A (0.4 or 0.8 mg, daily) on craving and reinforcing effects produced by administration of cocaine in cocaine-dependent, non-treatment seeking participants. Rivastigmine is a carbamate derivative that inhibits both AChE and BuChE with equal potency and has selectivity for central activity. Huperzine A is an innovative drug choice for this revised application and is derived from the Chinese herb Huperzia serrata. Huperzine A is a potent cholinesterase inhibitor, and has several other effects in brain (via DA, NMDA and GABA, as well as antioxidant effects and neuroprotection) that may ultimately contribute to its efficacy. In the proposed studies, we will include only participants exhibiting cocaine-induced craving prior to randomization; a strategy predicted to increase statistical power to detect effects of medication treatment on this specific symptom. The public health significance of the proposed project is clear. No medications are currently available for prevention of relapse in patients who are addicted to cocaine, and AChE inhibitors are predicted to be useful for this indication. PUBLIC HEALTH RELEVANCE: No medications are currently available for prevention of relapse in patients who are addicted to cocaine, and acetylcholinesterase inhibitors are predicted to be useful for this indication. To this end, we propose a human laboratory research study to evaluate the effects of rivastigmine or huperzine A on craving and reinforcing effects produced by administration of cocaine.

描述（由申请人提供）：乙酰胆碱（ACh）参与大脑奖励和学习功能，对该神经递质系统的干扰可能导致物质滥用障碍。动物研究表明，毒蕈碱乙酰胆碱受体在可卡因增强和非增强反应中的重要性，乙酰胆碱酯酶（AChE）抑制剂减少了啮齿动物的甲基苯丙胺寻求行为。与这些结果一致，我们组最近完成的一项双盲安慰剂对照研究表明，在实验室中使用AChE抑制剂rivastigmine治疗可减少甲基苯丙胺给药产生的渴求。在本申请中，我们提出了一项人体实验室研究，以评估卡巴拉汀（3或6 mg，每日）或石杉碱甲（0.4或0.8 mg，每日）对可卡因依赖性，非寻求治疗的参与者中可卡因给药产生的渴望和强化效应的影响。卡巴拉汀是一种氨基甲酸酯衍生物，对AChE和BuChE的抑制效力相同，对中枢活性具有选择性。石杉碱甲是本次修订申请的创新药物选择，来自中国草药蛇足石杉。石杉碱甲是一种有效的胆碱酯酶抑制剂，并在大脑中有几种其他作用（通过DA，NMDA和GABA，以及抗氧化作用和神经保护作用），最终可能有助于其疗效。在拟议的研究中，我们将仅纳入随机化前表现出可卡因诱导的渴望的参与者;预计这一策略将增加统计功效，以检测药物治疗对这种特定症状的影响。拟议项目的公共卫生意义是明确的。目前没有药物可用于预防可卡因成瘾患者的复发，预计乙酰胆碱酯酶抑制剂可用于该适应症。公共卫生关系：目前没有药物可用于预防可卡因成瘾患者的复发，预计乙酰胆碱酯酶抑制剂可用于该适应症。为此，我们提出了一项人体实验室研究，以评估卡巴拉汀或石杉碱甲对可卡因给药产生的渴求和强化效应的影响。
