Lurasidone is a second-generation antipsychotic newly approved by the U.S. Food and Drug Administration for the treatment of schizophrenia. Similar to most other second-generation antipsychotics, lurasidone is a full antagonist at dopamine D2 and serotonin 5HT2A receptors. Efficacy within the dose range of 40-120 mg/d was established in four 6-week, randomized, controlled trials. The recommended starting dose is 40 mg/d and the maximum recommended dose is 80 mg/d. Doses above 80 mg/d do not appear to confer added benefit and may be associated with a dose-related increase in certain adverse reactions such as somnolence and akathisia. Lurasidone is administered once daily with at least 350 calories of food in order to optimize bioavailability. Lurasidone is primarily metabolized in the liver through the CYP3A4 enzyme system, and coadministration with drugs that are strong inhibitors of CYP3A4 (such as ketoconazole) or strong inducers (such as rifampin) are contraindicated. Lurasidone is associated with minimal weight gain and no clinically meaningful alterations in glucose, lipids, or the ECG QT interval.
