         2012年6月22日,欧洲药品管理局(EMA)发布信息,推荐限制托哌酮的使用,仅限用于卒中后痉挛的口服治疗。

   19世纪60年代以来,托哌酮作为一种肌肉松弛药在数个欧洲国家应用,包括神经系统疾病引起的痉挛、脊柱或大关节疾病导致的肌痉挛。
  
        欧洲人用药物委员会(CHMP)发起了一项关于托哌酮的回顾研究,其原因是该药物上市后发现数例超敏反应,以及该药对一些适应证的有效性不足。事实上,超敏反应比既往发现的更为显著,且与在不同适应证中的关系并不确定。

       CHMP称托哌酮仅在口服治疗卒中后痉挛时获益超过风险。因此,医师应该停止对除卒中后痉挛以外的所有其它适应证使用托哌酮,且不该再使用注射制剂。目前正在使用托哌酮注射液的非卒中后痉挛患者应该在复诊时与医师主动沟通并改用其它合适的替换治疗方案。

  患者在使用托哌酮时应该警惕发生超敏反应的可能性。如果出现以下症状:面部潮红、皮疹、严重瘙痒(伴皮肤局部隆起)、呼吸困难、吞咽困难、心率增快、低血压或血压迅速降低,应立即停止治疗并咨询医师。

  CHMP的意见将呈送至欧委会进一步由整个欧盟采纳。
