Regards to chemicals/drugs: How do delivery systems work?

[nukeman]

Hey all,

How do drug delivery systems work?

Lets say I have a drug that I want to test out, let's called it DrugX. Now drugX will not work by it self because there is something in the body that kills it right away, or it can't bypass the bloodbrain barrier.

Now, I have this chemical called MoleucleX, it can get DrugX into the body no problem, or it can get past the blood brain barrier.

So... How do you combine them? Is it as simple as just mixing them together and then giving it to the subject?

Formulation can be more important than the molecule itself in order to get a drug to actually work.
