Used primarily in the treatment of schizophrenia and acute agitation associated with schizophrenia or bipolar disorder. It functions as an antipsychotic by modulating dopamine and serotonin activity in the brain. The succinate salt form allows for improved solubility, making it suitable for both oral and injectable formulations. The inhaled form is used for rapid control of agitation in adults, offering quick onset of action with reduced systemic exposure. It is also occasionally used off-label for managing severe nausea, vomiting, or anxiety when other treatments are ineffective.
