How Does It Work?Quetiapine belongs to a group of medications called atypical (or second-generation) antipsychotic medications. It is not entirely known how quetiapine works in the treatment of schizophrenia or bipolar disorder. However, it is known that the medication blocks or lessens the effects of several chemicals in the brain. These chemicals (such as dopamine and serotonin) may be elevated in people with schizophrenia or bipolar disorder (also known as manic depression).
Quetiapine is not a cure for bipolar disorder or schizophrenia. It only helps to control symptoms (see Symptoms of Schizophrenia or Bipolar Disorder Symptoms).
