Where is Olanzapine used and how does it work?
Olanzapine is used for the treatment of certain mental/mood disorders such as schizophrenia and bipolar disorder. This also helps to control your mood. Olanzapine is in the class of drugs known as atypical antipsychotics that helps restore the balance of certain natural substances in the brain.
This is an FDA-approved medication that works in the brain which affects the activity of various neurotransmitters. It is particularly dopamine and serotonin or also known as 5HT. Dopamine and serotonin are neurotransmitters known to be involved in regulating behavior, mood, perception, and thinking. Mental/mood disorders appear to be caused by disturbances in the activity of neurotransmitters in the brain. This medication blocks the receptors in the brain that dopamine acts on and prevents the excessive activity of dopamine. In this way, it helps to control symptoms of schizophrenia and bipolar disorder.
