问题 单项选择题

下列关于膜剂的叙述中错误的有

A.膜剂系将药物溶解或均匀分散在成膜材料中制成的薄膜状固体制剂

B.无论何种剂型都能改制成膜剂

C.膜剂制备方法简单,劳动保护问题较少

D.膜剂适于多种给药途径

E.可制成不同释药速度的膜剂

答案

参考答案:B

解析:膜剂系指药物溶解或均匀分散于成膜材料中加工成的薄膜制剂,适合与多种给药途径。膜剂的特点有:工艺简单;成膜材料较其他剂型用量小;含量准确;稳定性好:吸收快;膜剂体积小,质量轻,应用、携带及运输方便。采用不同的成膜材料可制成不同释药速度的膜剂,既可制备速释膜剂又可制备缓释或恒释膜剂。缺点是载药量小,只适合于小剂量的药物,膜剂的重量差异不易控制,收率不高。

阅读理解

Read a lot, I mean a lot! You have to increase your ability for reading. Many students are in the habit of reading only when their exams are approaching while some others read only what they are taught or things that must be read because it is in their curriculum. But listen to me now, I am telling you from my own experience that it is a very bad habit and it is not enough to improve your intelligence.

You have to learn and get ready to become versatile in your reading. The fact that you are studying medicine in school does not mean that you should not know one or two things on politics.

Many people have complained to me that they find it hard to read stuffs like novels but I just shake my head in pity for them because it is obvious they have failed to realize the truth in that wise saying by Margaret Fuller that “today a READER, tomorrow a LEADER!”

When you read, you get to “see” so many places and it will be as if you have visited those places in real life. This is because reading will improve your imagination and creativity and understanding. You also get experience from learning about how people dealt with their various problems thereby saving you from going through the pains and difficulties they must have gone through!

Reading will also help you in improving your vocabulary because you will certainly start coming across so many new words which you will try as much as possible to get accustomed to with the help of the dictionary! The good thing about increasing your vocabulary is that it will also improve your thinking ability. After all, we think in words and the more words you know, the easier it will become for you to express yourself or your thoughts.

And when you read, make sure you read so wide because the more you read, the more you know and the more you know the more intelligent you can become.
