The motor and cognitive effects of a selective D-1 dopamine receptor agonist, SKF 39393, were assessed in patients with Huntington's disease, Gilles de la Tourette's syndrome, tardive dyskinesia, and torsion dystonia, using a double-blind placebo-controlled design. Over daily doses ranging from 3.2 to 32 mg/kg and treatment intervals extending from one to seven weeks, no consistent changes could be discerned. The contribution of D-1 receptor mediated mechanisms to the pathophysiology of hyperkinetic extrapyramidal disorders remains uncertain.
采用双盲安慰剂对照设计,评估了选择性D-1多巴胺受体激动剂SKF 39393对亨廷顿舞蹈症、抽动秽语综合征、迟发性运动障碍和扭转性肌张力障碍患者的运动和认知影响。在每日剂量范围为3.2至32mg/kg且治疗间隔为1至7周的情况下,未发现一致的变化。D-1受体介导的机制对运动过度性锥体外系疾病病理生理学的作用仍不确定。
