Abstract
本发明提供了杂环胺类化合物用于制备治疗纤维肌痛综合症和慢性疲劳综合症的药物的用途。
Description
本发明是2001年4月17日递交的申请号为01806849.9、发明名称为“用于治疗纤维肌痛和慢性疲劳综合症的化合物”的中国专利申请的分案申请。
技术领域
本发明涉及杂环胺类化合物用于制备治疗纤维肌痛综合症和慢性疲劳综合症的药物的用途。
背景技术
慢性疲劳综合症(CFS),也被称作慢性疲劳免疫障碍综合症,年轻都市专业人员(yuppie)流行病;疲劳-慢性,和慢性疲劳和免疫机能障碍综合症,在临床上被定义为具有深度疲惫或疲劳特征的病症。另外,患有CFS的病人通常具有多种非特异性症状,包括虚弱、肌肉疼痛、嗜睡、不适、发热、喉咙痛、淋巴结触痛、记忆力衰退和/或精神集中力下降、失眠和抑郁。目前还不清楚CFS的准确诱因,并且尽管通常进行多种试验来排除病症的其它可能性诱因,但还没有确诊CFS的特异性试验。
纤维肌痛综合症(FMS),也被称作纤维肌痛、纤维肌炎、纤维组炎或肌筋膜痛综合症,是一种特征在于纤维组织、肌肉、腱和其它结缔组织中出现的广布的疼痛的风湿性病症、疲劳、头痛、缺乏恢复性睡眠和麻木。因此FMS与CFS具有许多共同的临床特征。与CFS类似,也没有FMS的特异性诊断试验。
许多种药物通常被用来治疗CFS和FMS。比较普遍的药物包括安眠药、免疫抑制剂、其它多种处方药和一系列非处方药。其它处方药物包括阿片样拮抗剂、钠潴留剂/β阻断剂、钙通道阻断剂/组胺阻断剂、抗抑制剂、变态反应药物和急性焦虑药物。然而,还没有已知的永久性消除CFS或FMS症状的药物。另外,目前使用的许多药物产生从轻微的副作用如倦睡、头昏和噁心到严重的副作用如瘾癖和肝脏损伤。
因此,亟需一种比较有效的治疗慢性疲劳综合症和纤维肌痛的方法。下面,本发明公开了几种可被制成用于治疗这些病症的制剂的化合物。

Pharmacia & Upjohn公司提供了描述CABASER、其药学动力学、临床研究、适应征和用途、禁忌征和警告以及帕金森氏病患者的包装盒插件。该包装盒插件以及它的说明书被本文引用作为参考。
卡麦角林的口服有效用药剂量范围从约0.01至约10.0mg/剂量/人,优选地从约0.25至约10.0mg/剂量/人,更优选地从约1至约6mg/剂量/人,甚至更优选地从约1至约2mg/剂量/人。在上述剂量范围内,卡麦角林通常每日服用一次或两次;然而,对于某些病人来说,服用次数可以减少到一星期三次,一星期两次或一星期一次。对一名特定的患者来说,剂量大小和服用次数的调配可以由处置医生来容易地进行调整。
和卡麦角林用药剂量有关的疗效和副作用似乎主要与个体敏感性有关。某些情况下针对适当的患者,可以得到一个最佳剂量,例如,最初以0.5至1mg/患者/天的剂量给患者施用低剂量的卡麦角林,然后在一个星期内将剂量调高到2、4、8或10mg/患者/天。病症较轻的患者预计需要较少的药量。例如,某些情况下,0.05、0.1或甚至0.25mg/人的剂量可能是合适的。病症较重的患者和已接受了多巴胺能药物治疗的患者预计需要较大的药量。精确的剂量可以由处置医生容易地进行确定,同时需要考虑以下因素如病情的进展状况、患者的体重和年龄、其它药物如L-多巴或左旋多巴是否用药以及用药程度和医生在确定给患者施用CNS药物的剂量之前通常考虑的其它因素。
