It is not entirely known how Zyprexa works for schizophrenia or bipolar disorder. However, it is known that it 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 or bipolar disorder.
In previous clinical studies of this drug for the treatment of schizophrenia, people taking it experienced improvements in their schizophrenia symptoms (including hallucinations and suspiciousness), compared to those not taking it. Longer studies also showed that Zyprexa can help people from needing to be hospitalized and can help symptoms from returning.
Previous clinical studies have also shown the drug to be effective for
bipolar disorder treatment. In these studies, the medication was effective when used alone or with other bipolar disorder medications.
