Amiodarone is an antiarrhythmic drug that is widely used for atrial fibrillation and other refractory arrhythmias. Although beneficial, its long-term administration is associated with adverse effects on various organs. One patient presented with amiodarone-induced liver injury, which led to liver failure. Computed tomography revealed a gradual increase in hepatic density over a long period following the initiation of amiodarone. Despite the discontinuation of the drug, the patient developed hepatic encephalopathy and subsequently died. This outcome highlights the drug's extended half-life, which caused persistent end-organ damage even after its withdrawal. Drug titration to the lowest effective dose and careful monitoring of annual liver function tests are important.
胺碘酮是一种抗心律失常药物,广泛用于治疗心房颤动和其他难治性心律失常。尽管有益,但长期服用会对多个器官产生不良反应。一名患者出现胺碘酮所致肝损伤,进而发展为肝衰竭。计算机断层扫描显示,开始服用胺碘酮后,肝脏密度在很长一段时间内逐渐增加。尽管停药,但患者仍发生肝性脑病,随后死亡。这一结果凸显了该药物的半衰期延长,即使停药后仍会导致持续的终末器官损害。将药物滴定至最低有效剂量并仔细监测年度肝功能检查非常重要。
