some of them have to do with what Caitlin mentioned.

其中的一些与凯特琳提出的有关
If you want a drug that works in the eye, for example,

例如如果你想要一个用于眼睛的药物
a drug to treat glaucoma,

来治疗青光眼
why take a drug orally and expose your whole body to the drug

那何须口服药物使你的全身都接触到呢
when you could just put drops in your eye directly?

这时只需要把药物直接滴入眼睛即可
And that's how many glaucoma drugs are delivered?

并且有多少青光眼药物被输送进来了呢
You might have eye drops that you just put into the space underneath your eye,

例如你也许把眼药水滴在眼睑的下面
for example, and that's a more targeted delivery.

那就是靶向性更强的输送
Targeted because you are putting the drug at the site where it's needed.

靶向性强是因为将药物施用在所需的位置
I'm sure you have examples of that;

我相信你们也有这样的例子
