Iloperidone: A Clinical Overview

Iloperidone is a new second-generation (atypical) antipsychotic medication approved for the treatment of schizophrenia in adults. The target dose of 6 mg bid can be achieved in 4 days, with titration recommended to minimize postural hypotension. The maximum recommended dose is 12 mg bid. The tolerability profile of iloperidone is noteworthy in terms of modest weight gain, no medically important changes in lipid and glucose levels, little in the way of prolactin elevation, and absence of extrapyramidal side effects, including akathisia. However, iloperidone can prolong the QTc interval on electrocardiogram. Iloperidone may be best suited for patients who are sensitive to akathisia or who are unable to tolerate the sedation and weight gain that can occur more frequently with other antipsychotics.
