【通用名称】盐酸安非他酮片
【成份】盐酸安非他酮
【药理毒理】安非他酮是去甲肾上腺素、5-羟色胺、多巴胺再摄取的弱抑制剂，对单胺氧化酶没有抑制作用。本品抗抑郁作用机制尚不清楚，可能与其抑制去甲肾上腺素和/或多巴胺的作用有关。
【适应症】用于治疗抑郁症。
【用法和用量】口服。用药时从小剂量开始，起始剂量为一次75mg（1片），一日2次；服用3天后，逐渐增大剂量到一次75mg（1片），一日3次；以后逐渐增加至每日300mg的维持剂量。3日内剂量增加不超过一日100mg。最大剂量不超过一次150mg（2片），一日3次，用药间隔不得少于6小时。
【不良反应】常见口干、失眠、头晕、头痛/偏头痛、易怒、恶心/呕吐、便秘、水肿、皮疹、尿频等不良反应。偶见肝功能异常、胃炎、幻觉、食欲减退和体重改变等。贫血、共济失调等罕见。
【禁忌】1．癫痫发作患者。2．使用其他含有安非他酮成分药物的患者。3．贪食症或厌食症的患者。4．对安非他酮或本品所含任一成份过敏者。
【注意事项】1．盐酸安非他酮有诱发癫痫的可能性。以下措施可以使癫痫发作的风险减至最低：每日最大给药量不超过450mg；每日三次给药，单次给药量不超过150mg；逐渐增加给药量。2．有癫痫病史、颅脑肿瘤或其它有癫痫倾向、正在服用其它降低癫痫发作阈的药物（如抗精神病药、抗抑郁药、甾体化合物）的患者慎用。3．与单胺氧化酶（MAO）抑制剂不能合并使用。MAO抑制剂与安非他酮的服用间隔至少应为14天。4．严重肝硬化患者慎用。这部分患者服用本品时，最大剂量不超过75mg，每日服用一次。

【药物相互作用】 1．细胞色素P450IID6代谢的药物：体外试验表明安非他酮和羟安非他酮是CYPIID6酶的抑制剂，因此正在使用CYPIID6酶代谢药物治疗的患者服用安非他酮时，应当考虑减少原来药物的剂量，特别是那些治疗指数窄的药物。这些药物包括某些抗抑郁药物（如：去甲替林，米帕明，地昔帕明，帕罗西汀，氟西汀，舍曲林），抗精神病药（如：氟哌啶醇，利培酮，甲硫达嗪），b-阻断剂（如：美托洛尔），抗心律失常药物（如：普罗帕酮，哌氟酰胺），同时在合并治疗开始时应当使用最小剂量。2.MAO抑制剂：动物研究显单胺氧化酶抑制剂（MAOI）苯乙胼可以增加安非他酮的急性毒性。3.左旋多巴：临床资料表明同时使用安非他酮和左旋多巴后，副作用发生率可能升高。服用左旋多巴的患者同时服用本品时应谨慎，从最小剂量开始使用，然后逐渐加量。4.降低癫痫发作阈值的药物：本品与降低癫痫发作阈值的药物（如：抗精神病药物，抗抑郁药物，茶碱，类固醇化合物等）合用或突然中断苯二氮卓类药物治疗后使用本品时应减少剂量，剂量的增加应缓慢。
