Features of managing patients with amiodarone-induced thyrotoxicosis in real clinical practice

Amiodarone is an antiarrhythmic drug that is widely used in clinical practice to control various types of arrhythmias. One of the most significant side effects of amiodarone therapy is thyroid dysfunction, which is observed in about 15–20% of patients. This article presents a clinical case of a 55-year-old patient with a paroxysmal form of atrial fibrillation, for which amiodarone therapy was performed with the development of manifest amiodarone-induced thyrotoxicosis, refractory to drug therapy with glucocorticosteroids and thyrostatics. Due to the ineffectiveness of drug therapy, a total thyroidectomy was performed, which led to a rapid resolution of thyrotoxicosis and normalization of the heart rhythm.
