神经松弛剂具有抗精神病作用,可产生锥外系副作用,包括治疗早期出现的急性肌张力障碍、静坐不能、帕金森氏综合征,这些症状经减药和使用抗胆碱药而缓解;迟发性运动障碍(TD)出现于治疗后期,特征性表现是口—面—咀嚼运动障碍,抗胆碱药不能使这种障碍消失反而会加重。减药时也往往加重,可能是一种不可逆的障碍。撤药性运动障碍是在服神经松弛剂治疗一段时间后突然停药时出现,临床表现常与TD相同,但几天或数周内可自行缓解,应用抗胆碱药效果不大。撤药性的运动障碍可以是TD发展的早期阶段,但仍是可逆的。异成塞平(Amoxapine)属三环二苯氧氮(艹卓)类,是神经松弛剂克塞平的去甲基代谢物,有明 Nerve relaxants have antipsychotic effects and can cause extrapyramidal side effects, including the treatment of acute dystonia that occurs early, impotence, Parkinsonism, which are relieved by the use of anticholinergics and anticholinergics; tardive dyskinesia (TD) appears in the later stage of treatment, the characteristic appearance is mouth-side-chewing movement disorder, anticholinergics can not make this disorder disappear but will aggravate. Medication often also increase, may be an irreversible obstacle. Withdrawal of drug dyskinesia in the treatment of nerve relaxants after a period of sudden withdrawal when the clinical manifestations and TD often the same, but a few days or weeks can be self-remission, the application of anticholinergic effect is not. Disabling dyskinesia can be an early stage of TD development, but it is still reversible. Amoxapine belongs to the class of tricyclic diphenoxazepines, which are demethylated metabolites of the neuroleptic agent,
