美国FDA批准止痉药盐酸环苯扎林缓释胶囊上市
美国FDA批准ECR制药公司的骨骼肌松弛药盐酸环苯扎林(cyclobenzaprineHC1)缓释胶囊(商品名：Amrix)上市，用于解除急性骨骼肌疼痛引起的痉挛。剂量规格：盐酸环苯扎林15mg／粒，30mg／粒。环苯扎林解除局部骨骼肌痉挛而不干扰肌肉功能，对中枢神经系统引起的肌肉痉挛无效。在对健康男性志愿者(n=15)单剂研究中，AUC0-168与AUC0-∞的剂量平均算术计算值显示Amrix30mg约分别较Amrix15mg高16％和10％。Amrix30mg的Cmax约较Amrix15mg高20％。环苯扎林的T1／2和血药达峰时间两种剂量相近。
采用单剂Amrix30mg对健康成人志愿者(n=15)进行食物影响的研究显示。药物与食物同时服用的生物利用度较空腹服药在统计上显著提高。胃内有食物时，环苯扎林的Cmax增加35％，AUC0-168与AUC0-∞增加20％。以多剂Amrix30mg对健康成人志愿者(n=35)进行一日1次服用7日的研究，结果表明血药浓度达到稳态时环苯扎林的累积浓度为单剂的2．5倍。
