ADMET

代谢
吡喹酮口服给药。帕莫酸盐的溶解性差提供了减少从胃肠道吸收的优势,并允许药物到达并作用于大肠内的寄生虫。吡喹酮的代谢迅速。吸收的药物部分在肝脏代谢。
Pyrantel is administered orally. The poor solubility of the pamoate salt offers the advantage of reduced absorption from the gastrointestinal tract and allows the drug to reach and act against parasites in the large intestine. Metabolism of pyrantel is rapid. The absorbed drug is partly metabolized in the liver.

制备方法与用途

驱肠虫药:噻嘧啶

**噻嘧啶**又叫抗虫灵,是一种广谱驱肠虫药。本品为淡黄色结晶粉末,无臭、无味,易溶于碱而难溶于。它通过阻滞肠道寄生虫神经肌的作用机制,麻痹虫体并使其随粪便排出体外。临床用于驱蛔虫、蛲虫和钩虫,治疗效果优于驱蛔灵、扑蛲灵、苄宁等药物,也可用于家畜驱肠虫。

用法与用量:驱蛔虫5~10mg/kg/次;驱钩虫同样剂量,连续3日;驱蛲虫则为5mg/kg/日,连服1周。服用本品计量应按基质计算,半空腹状态下效果更佳,无需额外服用泻药。本药可能会有轻微反应,一般不需特别处理。

孕妇、冠心病、溃疡病患者慎用;其他急性疾病患者则应缓用。

理化性质

嘧啶常用其双羟酸盐和酒石酸盐形式。双氢酸噻嘧啶为淡黄色粉末,在二甲基甲酰胺中略溶,乙醇中极微溶解,中几乎不溶;而酒石酸嘧啶则易溶于

研发历史

在20世纪50年代中期,辉瑞公司的研究者们为了寻找新的抗肠虫药建立了筛选项目。通过不同微生物接种小鼠,许多化合物被筛选出,其中仅化合物Ⅰ显示出活性证据。然而,它对羊的口服作用很小,可能是因为解。

随后,为抵抗这种解,在两个环之间用亚甲基取代原子桥,并合成了一系列同类物。噻嘧啶(pyrantel)通过增大四氢嘧啶环而得到最佳活性,是一种广谱、高效且低毒的胃肠线虫驱除药。嘧啶(oxantel)是其一种类似物,在小鼠实验中效力仅为噻嘧啶的1/10,但它对绦虫具有独特的疗效。

药理作用

本品作为去极化神经肌肉阻滞剂,能抑制虫体胆碱酯酶,使乙酰胆碱胆碱能神经末梢大量堆积,从而引发虫体肌肉剧烈收缩和痉挛性麻痹。这使得虫体无法附着于肠壁,并随粪便排出体外,不会引起胆道或肠道梗阻。

酒石酸嘧啶易被单胃动物充分吸收,而双羟酸噻嘧啶因难溶于,在消化道后段具有较好的驱蛲虫效果。

不良反应

嘧啶毒性很低,在高于治疗量5~7倍时仍未见宿主中毒反应。对孕备、幼龄动物也无不良临床反应;但马匹对酒石酸盐较敏感,大剂量下可见运动失调。

药物相互作用 注意事项
  1. 妊娠及虚弱动物禁用本品,尤其是酒石酸嘧啶
  2. 酒石酸嘧啶在大动物(特别是马)中需精确计量使用。
  3. 因噻嘧啶遇光易失效,双羟酸盐应配制混悬液后及时使用;而酒石酸盐多用预混剂混入饲料给药。
