Abstract

Introduction: Iloperidone is a novel antipsychotic medication approved for the treatment of schizophrenia in adults with efficacy similar to its class counterparts. The purpose of this article is to describe the safety profile of iloperidone and its clinical implications. Areas covered: A PubMed search was undertaken on May 10, 2013, using the keyword iloperidone. Of the 121 articles that resulted, those with primary sources of information, along with secondary sources with an emphasis on drug safety, were included in this article. Iloperidone was found to have lower extrapyramidal symptom (EPS) and akathisia rates compared to haloperidol and risperidone. Twelve percent of patients experienced clinically significant weight gain, largely during initiation phase of treatment. No other clinically significant metabolic abnormalities were observed. QTc interval was increased by 10 ms, comparable to the effect observed with ziprasidone. QTc prolongation was heightened under inhibition of CYP2D6 and CYP3A4. Orthostatic hypotension was a common effect seen in the first week of treatment. Expert opinion: The favorable EPS and akathisia profile of iloperidone makes it an attractive choice for patients whose compliance is limited by these effects. However, the slow titration schedule adapted to reduce orthostasis may limit the use of this agent in an acute setting.
