The powder in the capsules should be mixed well when you receive them. But for potent drugs it is rather risky depending on the drug.
I do half caps on some supplements (tryptophan), for example.
But there it is less of a risk.
And yes you can buy empty capsules. Some health food stores, and online.

Some people do this when tapering off certain drugs, like SSRIs that don't come in smaller doses. You just have to be very careful.
