C.洛伐他汀

D.多巴酚丁胺

E.米诺地尔

答案

参考答案:E

解析:

1.本题考查的是抗心律失常药。胺碘酮不良反应:(1)一般不良反应:恶心、呕吐、嗜睡、头痛等;甲状腺功能紊乱、震颤、角膜碘微粒沉淀。(2)严重不良反应:为致死性肺毒性和肝毒性,如间质性肺炎、肺纤维化、肝炎等。静注时可见血栓性静脉炎、血压下降。(3)心脏毒性:窦性心动过缓极为常见,也可出现严重心动过缓、房室传导阻滞等。

2.本题考查的是抗心律失常药。维拉帕米(异搏定)药理作用及临床应用:选择性阻滞钙通道,抑制Ca2+内流,抑制4相缓慢去极化,使自律性降低,心率减慢;同时降低房室结0相去极化速度和幅度,使房室传导速度减慢,ERP延长,有利于消除折返。对室上性和房室结折返引起的心律失常效果好,是治疗阵发性室上性心动过速首选药,对心房扑动、心房颤动、急性心肌梗死、心肌缺血及强心苷中毒引起的室性早搏也有效。还可用于伴有冠心病或高血压患者。

3.本题考查的是抗心律失常药。奎尼丁不良反应:不良反应多,毒性较大,安全范围小。(1)消化道反应:恶心、呕吐及腹泻等多见于用药早期。(2)心血管反应:低血压、血管栓塞、心律失常(3)金鸡纳反应:久用可引起耳鸣、听力减退、视力模糊、神志不清等。(4)奎尼丁晕厥:发作时意识丧失、四肢抽搐、呼吸停止、心室纤颤而死亡,称为“奎尼丁晕厥”。(5)变态反应:偶可出现皮疹、药热、血小板减少等过敏症状。
