Ventricular premature contractions associated with iloperidone

Abstract: Typical and atypical antipsychotic drugs are known to block potassium repolarization channels, prolong the QTc interval, and thereby predispose to ventricular tachyarrhythmias. We report a young male schizophrenic patient who experienced clinically significant and symptomatically distressing ventricular premature contractions (VPCs) in close temporal relation with iloperidone (8-16 mg/day) treatment; there had been no VPCs with prior exposure to risperidone, trihexyphenidyl, and olanzapine, nor with subsequent… Show more

“…Freeman reported two cases of retrograde ejaculation in two young males (aged 21 and 24 years) with schizophrenia after taking iloperidone (8 mg twice daily) for 2 or 3 weeks 17. Finally, a 29-year-old male taking iloperidone (16 mg/day) developed palpitations and was diagnosed with premature ventricular contractions 19. Symptoms in all these cases resolved after stopping iloperidone and switching to alternate therapies.…”

“…Although no cases of iloperidone-associated sudden death due to arrhythmias have been reported, avoidance of this drug may be prudent for patients who are medically susceptible to heart diseases or for patients taking concomitant medications that lengthen the QT interval. These precautions are similar to those for ziprasidone 39,40,59. So far, only one case of ventricular premature contractions has been published and is possibly related to iloperidone inducing alpha 2c receptor blockage 59…”

“…Concomitant medications must be closely monitored; the dose of iloperidone needs to be reduced in the presence of other drugs, especially drugs that are strong CYP450 inhibitors 53,59,61. So far, no evidence on iloperidone causing acute kidney injury (AKI) is available.…”
