A Case of Amiodarone-Induced Thyrotoxicosis A diagnostic and therapeutic dilemma
Journal Title: Sultan Qaboos University Medical Journal - Year 2009, Vol 9, Issue 3
Abstract
Amiodarone is an iodine rich agent widely used for the treatment of ventricular arrhythmias, paroxysmal supraventricular tachycardia, atrial fbrillation and flutter. However 14-18% of patients treated with amiodarone develop overt thyroid dysfunction in the form of either amiodarone-induced thyrotoxicosis (AIT) or amiodaroneinduced hypothyroidism (AIH). Two different types of AIT have been recognised and designated as Type 1 and Type 2. Distinguishing between the two is often difcult, but necessary for instituting appropriate treatment. We report a case of a 56 year-old male patient who was started on amiodarone for atrial fbrillation and then developed AIT. Te challenges in the diagnosis and management of these patients are discussed.
