FAQ

Is quetiapine a tricyclic antidepressant?

Quetiapine is a novel antipsychotic medication having structural similarities to tricyclic antidepressants (TCA). We present a case of a quetiapine overdose that originally resembled a TCA overdose and resulted in a false-positive TCA immunoassay.

Does quetiapine increase dopamine?

Quetiapine increases prefrontal dopamine release by antagonism of 5-HT2A receptors, a partial agonist of 5-HT1A receptors, and antagonism of a2 adrenoceptors.

What is the mechanism of action of quetiapine?

Quetiapine alleviates both positive and negative symptoms of schizophrenia and severe depression by acting on neurotransmitter receptors including serotonin and dopamine. It relieves both depressed and manic symptoms of bipolar illness.
