The potential relationship between QTc interval prolongation and ziprasidone treatment: three cases

摘要

QTc interval prolongation may appear as a consequence of both typical and atypical antipsychotic treatments. Ziprasidone, which is effective in treating schizophrenia, is associated with QTc prolongation. Although the prolongation of QTc with ziprasidone treatment is often pronounced, there is a scarce number of cases reported about the relationship between ziprasidone and QTc prolongation. Of the three cases presented in thiscase series, two cases showed values exceeding 0.50 s with ziprasidone treatment.
