In brief: Blood Brain Barrier
There is a layer of protection around the brain that makes it harder for certain medications to get to the brain.
If you need them to get there you have to use a higher dose.

In brief: BBB
Bbb= blood-brain-barrier. This physical structure (microscopic in scale) is what regulates and limits entry & exit of chemicals (including drugs) in the nervous system (cns).
Hence the need for higher blood level of drugs to expect penetration of antibiotics (or other drugs) into CNS in adequate quantity.
