    • This invention relates to a method of selectively enhancing the analgesic potency of morphine and other clinically used bimodally-acting opioid agonists and simultaneously attenuating development of physical dependence, tolerance and other undesirable side effects caused by the chronic administration of said bimodally-acting opioid agonists comprising the co-administration of a bimodally-acting opioid agonist which activates both inhibitory and excitatory opioid receptor-mediated functions of neurons in the nociceptive (pain) pathways of the nervous system and an opioid receptor antagonist which selectively inactivates excitatory opioid receptor-mediated side effects. This invention also relates to a method of using excitatory opioid receptor antagonists alone to block the undesirable excitatory side effects of endogenous bimodally-acting opioid agonists which may be markedly elevated during chronic pain. This invention further relates to a method of long-term treatment of previously detoxified opiate, cocaine and alcohol addicts utilizing said excitatory opioid receptor antagonists, either alone or in combination with low-dose methadone, to prevent protracted physical dependence, and to compositions comprising an excitatory opioid receptor antagonist of the invention and a bimodally-acting opioid agonist.
    • 本发明涉及选择性增强吗啡和其它临床使用的双峰作用阿片样物质激动剂的止痛效力的方法,同时减轻由慢性施用所述双模型作用的阿片样物质激动剂引起的物理依赖性,耐受性和其它不良副作用的发展,包括 共同施用双功能阿片样物质激动剂,其激活神经系统的伤害感受(疼痛)途径中的神经元的抑制性和兴奋性阿片受体介导的功能,以及选择性地使兴奋性阿片受体介导的副作用失活的阿片受体拮抗剂 。 本发明还涉及一种单独使用兴奋性阿片样物质受体拮抗剂来阻断内源性双重作用的阿片样物质激动剂的不期望的兴奋性副作用的方法,其在慢性疼痛中可能显着升高。 本发明还涉及一种利用所述兴奋性阿片受体拮抗剂单独或与低剂量美沙酮组合来长期治疗先前解毒的阿片剂,可卡因和酒精成瘾者的方法,以防止持久的物理依赖性,以及包含 本发明的兴奋性阿片受体拮抗剂和双峰作用的阿片样物质激动剂。

    • This invention relates to a method for treating a subject with irritable bowel syndrome (“IBS”) which comprises long-term administration of an opioid receptor antagonist at an appropriately low dose which will selectively antagonize excitatory opioid receptor functions, but not inhibitory opioid receptor functions, in myenteric neurons in the intestinal tract as well as in neurons of the central nervous system (“CNS”). The administration of the opioid receptor antagonist at a low dose enhances the potency of the inhibitory effects of endogenous opioid peptides present in the intestinal tract and the CNS, thereby reducing abdominal pain and stool frequency resulting from abnormally supersensitized excitatory opioid receptor functions. The invention also relates to a composition for treating a subject with IBS, which comprises an effective dose of an opioid receptor antagonist, and a pharmaceutically acceptable carrier.
    • 本发明涉及用于治疗肠易激综合征(“IBS”)的受试者的方法,其包括以适当低剂量长期施用阿片受体拮抗剂,其将选择性拮抗兴奋性阿片受体功能,但不抑制阿片受体功能 ,在肠道的肠系膜神经元以及中枢神经系统的神经元(“CNS”)中。 以低剂量施用阿片样物质受体拮抗剂增强了存在于肠道和CNS中的内源性阿片样物质肽的抑制作用的效力,从而降低了由异常超敏刺激性阿片受体功能引起的腹痛和大便频率。 本发明还涉及用IBS治疗受试者的组合物,其包含有效剂量的阿片受体拮抗剂和药学上可接受的载体。
