  • Title: Tardive Dyskinesia: New Treatments Available.
    Author: Limandri BJ.
    Journal: J Psychosoc Nurs Ment Health Serv; 2019 May 01; 57(5):11-14. PubMed ID: 31042295.
    Abstract:
    Tardive dyskinesia (TD), the choreoathetoid movements of fingers, arms, legs, and trunk and irregular stereotypical movements of the mouth, face, and tongue, has been the scourge of antipsychotic medications since the approval of chlorpromazine. TD tends to occur late in treatment and sometimes remains after discontinuation of the antipsychotic medication. With the recent approval of two medications, valbenazine (Ingrezza®) and deutetrabenazine (Austedo®), there are now treatments for this disfiguring consequence of dopamine-blocking medications. The current article distinguishes the movement disorder adverse effects of dopamine antagonists, explains the putative mechanism of action, and describes how best to treat TD with the new vesicular monamine transporter 2 (VMAT2) medications now approved by the U.S. Food and Drug Administration.
