分子式:
CAS号:

性质:指胎盘将母体血循环与胎儿血循环隔开的屏障,存在于母体循环与胎儿循环之间控制母体与胎儿物质流通的屏障,可防止外源性化合物对胎儿产生毒性,但作用很有限,因其对药物转运的特性与一般细胞膜屏障相似,故经胎盘屏障进入胎儿血循环的药物大多数属被动转运,即受药物脂溶性、分子大小、药物的解离度和极性的影响。如脂溶性高的药物硫喷妥易进入胎儿血循环,极性高的药物筒箭毒碱则不易进入胎儿血循环。在妊娠头三个月中,胎儿生长发育极其活跃,有些药物如雌激素、孕激素、糖皮质激素、抗癫痫药、抗肿瘤药易使胎儿发生畸形,孕妇应避免使用。即使在三个月后至出生前,也可影响胎儿组织器官的发育及功能。加之胎儿肝功能代谢率低,血浆蛋白结合率小,排泄少,易发生蓄积中毒。如四环素可影响骨生长及牙釉质发育,链霉素可致听神经功能减退,抗甲状腺药影响胎儿发育及功能,均应避免使用。
