Q

Ways drugs pass the BBB?

A

1) Mimic neurotransmitters and interact with neurotransmitter receptors
2) Interferes with the synthesis, production of the neurotransmitter in the nerve cell
3) Affect the release of the neurotransmitter or block the receptor on the postsynaptic neuron.
4) Many drugs act by disrupting the reuptake or breakdown process.
5) Other can inhibit the enzymes that are responsible for eliminating excess neurotransmitters.
- In both cases, the end result is an over-activation of the neurotransmitter system
