How Does Seroquel XR Work?
Seroquel XR belongs to a group of medications called second-generation (or atypical) antipsychotic medications. It is not entirely known how Seroquel XR works for treating schizophrenia. However, it is known that Seroquel XR blocks or lessens the effects of several chemicals in the brain. These brain chemicals (such as dopamine and serotonin) may be elevated in people with schizophrenia.
In one clinical study of Seroquel XR for the treatment of schizophrenia, people taking Seroquel XR experienced greater improvements in their schizophrenia symptoms, compared to people not taking Seroquel XR.
