  • 用途一:医药中间体。
  • Hazard Note:Toxic/Irritant
  • 骨骼肌松弛剂:氯唑沙宗是一种口服有效的中枢性骨骼肌松弛剂，化学结构与所有其他的肌肉松弛药完全不同，主要通过作用于脊髓和大脑皮层下中枢，抑制致肌肉痉挛有关的多突触反射而产生肌松作用，缓解痉挛所致疼痛并增加受累肌肉的灵活性。对乙酰氨基酚为非甾体类解热镇痛药，可能主要通过抑制前列腺素的合成而产生镇痛、解热作用。小鼠攀网法肌松作用研究表明，复方氯唑沙宗呈明显剂量依赖性肌松作用，对士的宁诱发的小鼠惊厥有良好的保护作用，复方氯唑沙宗片中对乙酰氨基酚的存在可使氯唑沙宗的作用增强。热板法镇痛试验表明复方氯唑沙宗有明显的镇痛作用，并呈剂量依赖性，对酒石酸锑钾所致小鼠疼痛性扭体反应也有明显的拮抗作用，且显示良好的剂量效应关系，试验结果显示对乙酰氨基酚和氯唑沙宗有镇痛协同作用。 以上信息由Chemicalbook的晓楠编辑整理。
