The term 'blood brain barrier' refers to the way in which certain molecules are prevented from passing from the blood stream into the central nervous system. The barrier consists of tight junctions around the tiny blood vessels (capillaries) which supply the brain with nutrients and oxygen. Large molecules, including some drugs, cannot penetrate the barrier.

All commonly used psychiatric drugs readily pass the BBB. This is not the reason for lack of response.
