项目摘要

Getting a drug to where it is needed is essential if it is to be efficient. Some drugs are effective when injected into the bloodstream or taken as tablets. For the cornea at the front of the eye, drugs can also be applied as eye drops. The problem with this, however, is that eye drops flow away from the cornea and end up under the eyelid or in the nasal passage. Thus, the drug in the eye drop is not active where it is needed. To overcome this problem we will bind drugs to thin films, which will be a bit like contact lenses. But the binding of the drug will not be tight. This means that when the film is worn like a contact lens the drug is steadily released into the cornea, exactly where it is needed. A special type of drug called a ROCK inhibitor can help damaged cells in the cornea recover. And because of this we will use a ROCK inhibitor as the drug in our new contact lens-type films, to establish how it is released into the cornea in a more targeted manner than with eye drops.

如果要使药物有效，将药物送到需要的地方是必不可少的。有些药物在注射到血液中或作为片剂服用时是有效的。对于眼睛前部的角膜，药物也可以作为眼药水使用。然而，这样做的问题是，眼药水会从角膜流走，最终流到眼睑下或鼻道中。因此，滴眼液中的药物在需要的地方没有活性。为了克服这个问题，我们将把药物绑定到薄膜上，这有点像隐形眼镜。但药物的结合力不会很紧。这意味着当薄膜像隐形透镜一样被佩戴时，药物会稳定地释放到角膜中，正是需要的地方。一种称为ROCK抑制剂的特殊类型的药物可以帮助角膜中受损的细胞恢复。正因为如此，我们将使用ROCK抑制剂作为我们新的隐形眼镜型薄膜中的药物，以确定它如何以比滴眼液更有针对性的方式释放到角膜中。
