Antibiotics?

How and why does the use of antibiotics effect the sympathetic nervous systemAntibiotics?
Not that I know of, since antibiotics obligation to cross the blood-brain barrier back affecting anything in the brain. The beta-lactam ring of antibiotics and even the other functionalities of the remaining antibiotics are reactive plenty in temper in that once exposed inside our body, they will do what they are supposed to do, which is to inhibit bacterial growth. By the time it reach the blood-brain barrier, should it do so, it would enjoy been degraded already, and the "remains" of the antibiotics want to have the right size and polarity to cross this obstruction (something that they cannot do even when degraded).
Only select molecules can get contained by that area, specifically the ones involved surrounded by the "fight or flight" response.
Hope this help!
It doesn't.
