A new study suggests that olanzapine (Zyprexa) may be helpful for the treatment of schizophrenia. In addition to helping patients with schizophrenia, olanzapine also may be helpful for patients with bipolar disorder.
“It’s an intriguing finding,” says Dr. John D. Ricks, director of the Department of Psychiatry at Mount Sinai School of Medicine and director of the Division of Neuropsychiatry and Psychiatry at Lenox Hill Hospital and the study’s lead author. “I think the new study’s finding is interesting.”
Zyprexa, a type of antipsychotic, is a combination of olanzapine (Zyprexa) and a quetiapine (Pali) that has been studied for several decades. Olanzapine is a newer generation of antipsychotic drugs, called atypical antipsychotics, that has been approved for the treatment of schizophrenia and bipolar disorder. Olanzapine and olanzapine-Pali are two new antipsychotic drugs that were approved by the U. S. Food and Drug Administration in 1996.
“Zyprexa and olanzapine are very similar medications,” Dr. Ricks says. “The antipsychotic drugs are similar in how they affect mood and behavior. So it’s interesting to see how they work to treat different types of bipolar disorder.”
While olanzapine has been approved to treat schizophrenia and bipolar disorder in the U. in 1998, the Food and Drug Administration has approved it for the treatment of bipolar disorder in the United Kingdom in 2003. Zyprexa is approved for the treatment of bipolar mania in adults as well as a mania associated with depression.
“It’s interesting to see that antipsychotic drugs are quite similar medications,” Dr.
A study published in the Journal of Neuropsychiatry and Psychiatry in February 2008 by Dr. John P. Cunha, lead author on the study, examined the effectiveness of olanzapine and olanzapine-Pali in treating schizophrenia. A total of 677 patients with schizophrenia who received at least one course of olanzapine and an olanzapine-Pali combination of at least one antipsychotic medication were treated with olanzapine or olanzapine-Pali alone or in combination with the other antipsychotic medication.
A total of 437 patients who completed the study were included, including the patients who were excluded from the study because of study exclusions. Of the total patients, 149 patients had a diagnosis of schizophrenia and 116 had a diagnosis of bipolar disorder.
The mean age of patients was 54.1 years (SD 10.1).
The patients were randomized to treatment with olanzapine alone or in combination with olanzapine-Pali, a new antipsychotic drug. The patients who received treatment with olanzapine-Pali and olanzapine-Pali were less likely to develop manic or mixed episodes, depressed mood, and had an increase in suicidal ideation and behavior than the patients who received treatment with olanzapine alone. The patients who received olanzapine-Pali alone were also less likely to develop manic or mixed episodes.
“The authors were very surprised at the results,” Dr. “The authors were interested in the finding that olanzapine and olanzapine-Pali helped patients with bipolar disorder to stabilize their bipolar disorder, which they were able to do, without the risk of mood episodes.”
The results of the study are published in the April 2008 issue ofBMJ.

Of the patients who completed the study, 146 (33.6%) were randomized to olanzapine or olanzapine-Pali alone, and 118 (34.2%) to olanzapine or olanzapine-Pali plus an olanzapine-Pali combination.
Olanzapine, commonly known by its trade name ZYOUN (), is a atypical antipsychotic prescribed to individuals who have been convicted of or appear in a prison riot. It belongs to a class of drugs known assecond-generation antipsychotics. It works by altering the levels of dopamine and serotonin in the brain, which in turn helps in regulatingthe appetite and mood.
The global olanzapine market was valued at USD 1.2 billion in 2023 and is projected to reach USD 1.8 billion by 2033, growing at a Compound Annual Growth Rate (CAGR) of 2.5% from 2024 to 2033[1][4].
