【药理毒理】雌二醇氮芥是依据“受体学说”设计的药物，是以雌二醇磷酸酯为载体的氮芥类化合物，具有烷化剂和雌二醇的双重作用。根据“受体学说”、不同的专一性，甾体类激素对不同的靶器官具有不同的专一性。甾体类激素与烷化剂的结合物有可能选择性地进入激素依赖性的瘤组织中，从而减轻了烷化剂对全身的作用。这不仅发挥了甾体类激素的作用，而且也加强了烷化剂的抗癌效应，同时相应降低了烷化剂的毒副反应。

（1）轻度胃肠道反应，如恶心、呕吐等：

【用法用量】静注：每日300～500mg溶于溶剂中静注，连用3周，然后改为每周2次；或改为口服；每日600～900mg，分2次。静脉或口服一般3～4周为1疗程，无效停用。 　　
【注意事项】附带的粉针溶剂需小心缓慢地加入雌二醇氮芥的安瓶中，并避免震动，以防止起泡沫。等渗盐水不能作为溶剂使用。
