摘要
Both amisulpride and valbenazine can prolong the QT interval, so combined use may increase the risk of ventricular arrhythmias including torsades de pointes. Risk is higher with electrolyte disturbances, bradycardia, or other QT-prolonging drugs. Valbenazine is also associated with somnolence, which may be additive.
