Description
Olanzapine is an atypical antipsychotic, approved by the FDA in 1996. Olanzapine is manufactured and marketed by the pharmaceutical company Eli Lilly and Company, whose patent for olanzapine proper ends in 2011.
Indication
For the acute and maintenance treatment of schizophrenia and related psychotic disorders, as well as acute treatment of manic or mixed episodes of bipolar 1 disorder. Intramuscular olanzapine is indicated for the rapid control of agitated patients.
Mechanism of Action
Olanzapine's antipsychotic activity is likely due to a combination of antagonism at D2 receptors in the mesolimbic pathway and 5HT2A receptors in the frontal cortex. Antagonism at D2 receptors relieves positive symptoms while antagonism at 5HT2A receptors relieves negative symptoms of schizophrenia.
