Aripiprazole-induced tardive dyskinesia treated with quetiapine: a case report

Abstract

Tomruk NB, Saatcioglu O, Yildizhan E, Alpay N. Aripiprazole-induced tardive dyskinesia treated with quetiapine: a case report.Background: Tardive dyskinesia (TD) is a serious, potentially irreversible side effect of antipsychotics. Although the risk is smaller, atypical antipsychotics still pose a risk. Aripiprazole is an atypical antipsychotic with a unique mechanism of action. It has a partial agonistic effect on the presynaptic D2 dopamine autoreceptor and antagonistic effect at postsynaptic D2 receptors.Method: There have been a few case reports of aripiprazole-induced TD. A case of aripiprazole-induced TD successfully treated with another atypical antipsychotic, quetiapine, is described and discussed in line with the recent literature.Results: TD showed rapid improvement with discontinuation of aripiprazole and initiation of quetiapine.Conclusion: Further studies are needed to ascertain the differential effects and side effects of second-generation antipsychotics in terms of TD.
