其他信息

  • 瑞香提取物:瑞香素是由瑞香科瑞香属植物长白瑞香中提取出来的有效成分,现已人工合成,试验表明瑞香素具有扩张冠状血管、增加冠脉流量、减少心肌耗氧量,改善心肌代谢、促进心功能恢复及抗血栓形成等作用。临床可用于心绞痛、冠心病、血栓闭塞性脉管炎等。也可用于风湿性关节炎,因还具有一定抗炎、镇痛作用。口服:1次450mg,1日3次。用药后偶有胃肠道反应。有出血倾向的患者及孕妇慎用。
  • 抗疑作用:白瑞香甙给家兔口服30~50mg/kg,可降低血液凝固性,作用最强在第2~3天,并持续1~3天。
  • 现代应用:现代临床用之治疗坐骨神经痛。采新鲜雪冻花烘干研粉,装入胶囊,每粒0.4克;另用碘化钾,亦装入胶囊,每粒0.6克(临服时装入)。服法:雪冻花胶囊2粒,碘化钾胶囊3粒为1剂,分3次服完。即第1晚服雪冻花胶囊1粒,第2晚服碘化钾胶囊2粒,第3晚服雪冻花,碘化钾胶囊各1粒。连服2剂为1疗程。若服1疗程无效者即停药; 病程长者可服2疗程。 其它:含多量伞形花内酯。白瑞香甙给家兔口服30~50毫克/公斤时,可降低 血液粘稠度,作用最强在第2~3天,并持续1~3天。并使血液对肝素的耐受性降低,第Ⅱ,Ⅶ,Ⅹ因子活性下降。血块弹力图上显示反应时间及血块形成延长。此种作用可被维生素K拮抗。白瑞香甙还能促进体内尿酸排泄。
