(+)-4-propyl-9-hydroxynaphthoxazine (PHNO) is a novel selective D2 agonist. The efficacy and safety of PHNO was studied in 10 Parkinsonian patients (Hoehn and Yahr Stage II or III) who continued to receive levodopa/carbidopa. At the lowest dose administered (0.25 mg tid), nine of the 10 patients improved with respect to rigidity, bradykinesia and tremor. At this dose there was one dropout because of severe orthostasis. Although there was a trend towards improvement in motor scores with the higher doses (0.5-1.0 mg tid), this was not statistically significant. At higher doses there were a total of four dropouts because of adverse effects such as nausea, vomiting and orthostatic hypotension. It appears that PHNO may prove to be efficacious in the treatment of Parkinson's disease.
(+)-4-丙基-9-羟基萘并恶嗪(PHNO)是一种新型的选择性D2激动剂。在10名继续接受左旋多巴/卡比多巴治疗的帕金森病患者(Hoehn和Yahr分期为II期或III期)中研究了PHNO的疗效和安全性。在给予的最低剂量(0.25毫克,每日三次)时,10名患者中有9名在强直、运动迟缓及震颤方面有所改善。在此剂量下,有1名患者因严重直立性低血压退出研究。尽管较高剂量(0.5 - 1.0毫克,每日三次)时有运动评分改善的趋势,但这在统计学上并不显著。在较高剂量时,共有4名患者因恶心、呕吐及直立性低血压等不良反应而退出研究。看来PHNO可能被证明对帕金森病的治疗有效。
