Metoclopramide is an antiemetic drug which occasionally produced acute dystonic reactions. Although known to interfere with central dopamine mechanisms, it is frequently used in Parkinson's disease to prevent levodopa-induced nausea and vomiting. In this study metoclopramide did not increase Parkinsonism or reduce levodopa-induced involuntary movements in patients with Parkinson's disease. Pimozide, by contrast, increased Parkinsonism and reduced involuntary movements. The capacity of metoclopramide to produce acute dyskinesias while being apparently free of Parkinsonism effects is pharmacologically unique and differentiates this drug from the phenothiazines and butyrophenones.
甲氧氯普胺是一种止吐药,偶尔会引起急性肌张力障碍反应。尽管已知它会干扰中枢多巴胺机制,但它仍常用于帕金森病,以预防左旋多巴引起的恶心和呕吐。在本研究中,甲氧氯普胺并未加重帕金森病患者的帕金森症状,也未减少左旋多巴引起的不自主运动。相比之下,匹莫齐特加重了帕金森症状并减少了不自主运动。甲氧氯普胺在产生急性运动障碍的同时,显然没有帕金森病效应,这在药理学上是独特的,使该药物与吩噻嗪类和丁酰苯类药物有所区别。
