问题 单项选择题 B型题

药物代谢的主要器官是()

A.肝脏

B.肾脏

C.肺

D.胆

E.心脏

答案

参考答案:A

解析:

本组题考查药物的吸收、分布、代谢、排泄。 排泄是指体内原型药物或其代谢物排出体外的过程。肾是药物排泄的主要器官,其次是胆汁排泄。还可经乳汁、唾液、呼气、汗腺等排泄,但排泄量很少。肠肝循环是指在胆汁中排出的药物或代谢物,在小肠中转运期间重新吸收而返回门静脉的现象。有肠肝循环的药物在体内能停留较长的时间。这类药物若与某些药物合用,或改变制剂工艺,或因病理原因使肠肝循环情况发生变化,立即会影响到药效和毒性。药物代谢主要在肝内进行。吸入气雾剂主要在肺部吸收。
