Seroquel Indication:

For the treatment of schizophrenia and acute manic episodes associated with bipolar I disorder, as either monotherapy or adjunct therapy to lithium or divalproex.

Seroquel Mechanism Of Action:

The mechanism of action of quetiapine, as with other drugs used to treat schizophrenia, is unknown. However, it is thought that the drug's therapeutic activity in schizophrenia is mediated through a combination of dopamine type 2 (D2) and serotonin type 2 (5HT2) receptor antagonism. Although quetiapine is known to bind other receptors with similar affinity, only the dopamine D2 and serotonin 5HT2 receptor binding is responsible for quetiapine's therapeutic activity in schizophrenia.
