What p450 enzymes are inhibited/induced by seroquel, (quetiapine) and what does a dopamine/norepinephrine antagonist do? Reduce dopamine levels? Specifics please?

What p450 enzymes are inhibited/induced by seroquel, (quetiapine) and what does a dopamine/norepinephrine antagonist do? Reduce dopamine levels? Specifics please?

Neither: Seroquel (quetiapine) passes through the cyp450 3a4 pathway & is extensively metabolized, but it neither inhibits nor induces the pathway itself. On the other hand, it's metabolism may be significantly affected by other medications. For instance, Dilantin induces the pathway causing seroquel (quetiapine) to be rushed through the pathway, leading to less-effective, lower blood levels. Antagonists are blockers. ...Read more

What happens when serotonine, dopamine, and norepirephrina from reuptake in the brain?

What happens when serotonine, dopamine, and norepirephrina from reuptake in the brain?

Increased levels: I believe you are asking what happens when these neurotransmitters are chemically prevented from being metabolized 're-uptake'. This is often accomplished by drugs like anti-depressants. The levels of the neurotransmitters are increased and their physiologic effects are secondarily increased. An example would be subjective feeling of pleasure from increased dopamine. ...Read more
