I'm currently studying neurological diseases of the brain and was told that medication usually have a hard time entering the brain because of the protective blod-brain barrier, which also makes it hard designing medication for these types of diseases.
This made me think of roaccutane. Wouldn't it be possible designing another form of the medication which doesn't affect the brain, but only the skin issues. Another type of vitamin A derivate?? All you people who study chemistry and know stuff about it, would this even be possible?? That would make heaps of people more acceptable to this drug including myself. I'm scared to death about possibly taking this drug..
