左旋多巴及多巴胺受体激动剂是目前治疗帕金森病(Parkinson’s Disease,PD)的有效药物。长期应用这些药物可引起诸多并发症,异动症就是一种常见运动并发症。但这两类药物诱发的异动症不完全相同,现就这两类药物诱发的异动症进行综合分析。以便对临床医师有所帮助。一、异动症的产生机制异动症是在PD治疗过程中比较普遍存在的并发症,它并不是左旋多巴治疗所特有的并发症,多巴胺受体激动剂,特别是半衰期短的药物,如：阿 Levodopa and dopamine receptor agonists are currently effective drugs for the treatment of Parkinson’s Disease (PD). Long-term use of these drugs can cause many complications, dyskinesias is a common motor complications. However, these two types of drug-induced dyskinesia are not exactly the same, are these two types of drug-induced dyskinesia were analyzed. In order to help clinicians. First, the mechanism of the production of dyskinesia is a common complication in the treatment of PD, it is not unique to the treatment of levodopa complications, dopamine receptor agonists, especially those with short half-life, such as: Ah
