The present invention relates to novel noncardiotoxic compounds and pharmaceutical compositions useful in the treatment of a variety of disorders including the treatment of depression, allergies, psychoses, cancer and gastrointestinal disorders. In particular, the present invention describes pharmaceutical compositions that mitigate life-threatening arrhythmias such as torsade de pointes. Torsade de pointes is a particular cardiac problem associated with many therapeutic agents and has been implicated as a possible cause of sudden death, particularly in those individuals with a past history of disturbances of cardiac rhythm, myocardial infarction, congenital repolarization abnormalities and cardiac risk factors such as hyperlipidemia and age. This arrhythmia is a variant of paroxysmal ventricular tachycardia associated with a prolonged QTc interval or prominent U waves on the ECG. Torsade de pointes is potentially lethal because it can progress to ventricular fibrillation, life-threatening arrhythmias or precipitate sudden death.
本发明涉及新型无心脏毒性化合物和药物组合物,用于治疗包括抑郁症、过敏、精神病、癌症和胃肠道疾病在内的各种疾病。具体而言,本发明描述了可以缓解危及生命的心律失常,例如扭转型尖波。扭转型尖波是与许多治疗剂相关的一种特殊心脏问题,已被指认为可能导致猝死的原因,特别是在那些有心脏节律紊乱、心肌梗死、先天性复极异常和心脏危险因素(如高脂血症和年龄)的个体中。这种心律失常是一种与心电图上QTc间期延长或U波显著的室性心动过速变异有关的心律失常。扭转型尖波有潜在致命性,因为它可能发展为室颤、危及生命的心律失常或引发猝死。
