问题 单项选择题 B1型题

能够避免药物受胃肠液及酶的破坏而迅速起效的片剂是()

A.肠溶片

B.分散片

C.泡腾片

D.舌下片

E.缓释片

答案

参考答案:D

解析:舌下片药物可直接经舌下黏膜吸收发挥全身作用,不经胃肠道消化,可避免首过效应。分散片分散均匀性采用崩解时限法测定,即在15~25℃水中应在3分钟内完全崩解。肠溶片为防止药物在胃内分解失效、对胃的刺激或控制药物在肠道内定位释放,可对片剂包肠溶衣。

Mr. White works in an office. He liked reading in bed when he was at school. It was bad for his eyes and now he is near-sighted. But he wouldn’t want anybody else to know about it and he never wears a pair of glasses. It often brings him some trouble.

One winter morning he was sent to a village school on business. He got off a bus at a stop in a small town. Then he had to walk there. The road to the village wasn’t smooth. There were stones here and there. He fell over several times and it made his clothes very duty. At last he got to the village. Suddenly it began to blow strongly and it got much colder. His hat was blown off while he was looking for the school. He had to run after it but he couldn’t catch it. He was wondering why his hat ran into a house as if it had legs. And then he ran into the house, too.

A big woman appeared and stopped him by shouting angrily, " What are you running after my hen for?"
