disopyramide and telithromycin (Major Drug-Drug)

GENERALLY AVOID: Telithromycin has the potential to prolong the QT interval of the electrocardiogram in some patients. Theoretically, coadministration with other agents that can prolong the QT interval may result in elevated risk of ventricular arrhythmias, including ventricular tachycardia and torsade de pointes, because of additive arrhythmogenic potential related to their effects on cardiac conduction.

MANAGEMENT: Telithromycin should be avoided in patients treated with class IA (e.g., disopyramide, quinidine, procainamide) or class III (e.g., amiodarone, dofetilide, sotalol) antiarrhythmic agents.
